Yashwant Sinha to lead debate on chopper scam

HAZARIBAG: BJP MP Yashwant Sinha will be the main speaker in Parliament on the AgustaWestland VVIP Chopper scam, which is top on the agenda of BJP and NDA.

Talking to the media here on Wednesday, Sinha said, "The decision was taken at L K Advani's residence on Tuesday. Although parliamentary affairs minister Kamal Nath said the government was ready for a debate on the issue and also for taking it up in the joint parliament committee (JPC), the BJP will prefer the entire investigation to be done by the CBI under the supervision of the Supreme Court."

He added that what has created suspicion in the minds of the Opposition parties is the fact that someone accused in the scam paid kickback to a particular family. "Neither the UPA nor the prime minister mentioned the name of the family, which accepted the bribe for finalizing the deal," he said.

Sinha was critical of the UPA government for holding the NDA responsible for starting the deal with the Agusta Chopper company. He questioned, "If there was any truth in that, why didn't the UPA government strike off the deal. The UPA must stop putting the blame on NDA for every deal that was struck."

He regretted the decision of the defence ministry to buy aircraft, which eventually turned into a scam. He added that it was a matter of grave concern and demanded the careful handling of another aircrafts deal worth over Rs 90,000 crore. Sinha also criticized the government for its failure to contain inflation. which has already reached the level of 5.4%.

He was surprised at the government's decision to table the food bill, which will further escalate inflation.

"Although the government was having 70 million tones of foodgrain in its stock, it did not release it in the market to check food inflation, which has gone up to 12%, the highest ever," he said. He blamed Prime Minister Manmohan Singh and the Union finance minister P Chidambaram for their failure to contain the inflation because of faulty economic policies.

Flu shot did poor job against worst bug in seniors

ATLANTA (AP) — For those 65 and older, this season's flu shot is only 9 percent effective against the most common and dangerous flu bug, according to a startling new government report.

Flu vaccine tends to protect younger people better than older ones and never works as well as other kinds of vaccines. But experts say the preliminary results for seniors are disappointing and highlight the need for a better vaccine.

For all age groups, the vaccine's effectiveness is moderate at 56 percent, which is nearly as well as other flu seasons, the Centers for Disease Control and Prevention said Thursday.

For those 65 and older, it is 27 percent effective against the three strains in the vaccine, the lowest in about a decade but not far below from what's expected. But the vaccine did a particularly poor job of protecting older people against the harshest flu strain, which is causing most of the illnesses this year. CDC officials say it's not clear why.

Vaccinations are now recommended for anyone over 6 months, and health officials stress that some vaccine protection is better than none at all. While it's likely that older people who were vaccinated are still getting sick, many of them may be getting less severe symptoms.

"Year in and year out, the vaccine is the best protection we have," said CDC flu expert Dr. Joseph Bresee.

To be sure, the preliminary data for seniors is less than definitive. It is based on fewer than 300 people scattered among five states.

But it will no doubt surprise many people that the effectiveness is that low, said Michael Osterholm, a University of Minnesota infectious disease expert who has tried to draw attention to the need for a more effective flu vaccine.

Among infectious diseases, flu is considered one of the nation's leading killers. On average, about 24,000 Americans die each flu season, according to the CDC.

This flu season started in early December, a month earlier than usual, and peaked by the end of year. Older people are most vulnerable to flu and its complications, and the nation has seen some of the highest hospitalization rates for people 65 and older in a decade.

Flu viruses tend to mutate more quickly than others, and it's not unusual for multiple strains to be spreading at the same time. A new vaccine is formulated each year targeting the three strains expected to be the major threats. But that involves guesswork.

Because of these challenges, scientists tend to set a lower bar for flu vaccine. While childhood vaccines against diseases like measles are expected to be 90 or 95 percent effective, a flu vaccine that's 60 to 70 percent effective in the U.S. is considered pretty good.

By that standard, this year's vaccine is OK. The 56 percent effectiveness figure means people have a 56 percent lower chance of winding up at the doctor for treatment of flu symptoms.

For seniors, a flu vaccine is considered pretty good if it's in the 30 to 40 percent range, said Dr. Arnold Monto, a University of Michigan flu expert.

Older people have weaker immune systems that don't respond as well to flu shots. That's why a high-dose version was recently made available for those 65 and older. The new study was too small to show whether that made a difference this year.

The CDC estimates are based on about 2,700 people who got sick in December and January. The researchers traced back to see who had gotten flu shots and who hadn't. An earlier study put the vaccine's overall effectiveness slightly higher, at 62 percent.

The CDC's Bresee said there's a danger in providing preliminary results because it may result in people doubting — or skipping — flu shots. But the data was released to warn older people who got shots that they may still get sick and shouldn't ignore any serious flu-like symptoms, he said.

The new data highlights an evolution in how experts are evaluating flu vaccine effectiveness. For years, it was believed that if the viruses in the vaccine matched the ones spreading around the country, then the vaccine would be effective. This year's shot was a good match to the bugs going around this winter, including the harsher H3N2 that tends to make people sicker.

But the season proved to be a moderately severe one, with many illnesses occurring in people who'd been vaccinated.

Las Vegas Strip Shooting Leads to 3 Dead

A drive-by shooting on the Las Vegas strip early this morning by the occupants of a Range Rover SUV, who shot at the occupants of a Maserati, caused a multi-car accident and car explosion that left three dead.

Police said that they believe a group of men riding in a black Range Rover Sport SUV pulled up alongside a Maserati around 4:20 a.m. today and fired shots into the car, striking the driver and passenger, according to Officer Jose Hernandez of the Las Vegas Metropolitan police department.

The Maserati then swerved through an intersection, hitting at least four other cars. One car that was struck, a taxi with a driver and passenger in it, caught on fire and burst into flames, trapping both occupants, Hernandez said.

The SUV then fled the scene, according to cops.

The driver of the Maserati died from his gunshot wounds at University Medical Center shortly after the shooting, according to Sgt. John Sheahan.

The driver and passenger of the taxi both died in the car fire.

At least three individuals, including the passenger of the Maserati, were injured during the shooting and car crashes and are being treated at UMC hospital.

Police are scouring surveillance video from the area, including from the strip's major casinos, to try and identify the Range Rover and its occupants, according to police.

They do not yet know why the Range Rovers' occupants fired shots at the Maserati or whether the cars had local plates or were from out of state.

No bystanders were hit by gunfire, Hernandez said.

"We're currently looking for a black Range Rover Sport, with large black rims and some sort of dealership advertising or advertisement plates," Hernandez said. "This is an armed and dangerous vehicle."

The Las Vegas Convention and Visitors Authority had no immediate comment about the safety of tourists in the wake of the shooting today.

French hostages probably separated, Hollande says

PARIS/MAIDUGURI, Nigeria (Reuters) - Seven French hostages abducted by suspected Nigerian Islamist militants have probably been separated into two groups and efforts are continuing to locate them, French President Francois Hollande said on Thursday.

French, Nigerian and Cameroonian officials earlier denied French media reports that the seven family members, who were seized in Cameroon on Tuesday and taken over the border, had been freed.

"It's best to work discreetly for now to identify the exact place where our citizens are being held - most likely in two groups - and work out how we can free them under the best conditions," Hollande told reporters.

Paris was "fully cooperating" with Nigeria and Cameroon, he added, noting that French troops were nearby as their base was in the Chadian capital N'Djamena, 150 km (93 miles) away.

The Nigerian military located the hostages and kidnappers between Dikwa and Ngala in the far northeast, a Nigerian military source in Borno said earlier on Thursday, asking not to be identified.

Dikwa is less than 80 km (50 miles) from the border with Cameroon where the three adults and four children were taken hostage on Tuesday.

A senior Cameroonian military official declined to comment, saying the matter was too sensitive.

French gendarmes backed by special forces arrived in northern Cameroon on Wednesday to help locate the family, a local governor and French defense ministry official said.

Citing a Cameroon army officer, French media reported earlier on Thursday that the hostages had been found alive in a house in northern Nigeria. That was denied by the France, Nigeria and Cameroon.

DIFFICULT SITUATION

The abduction was the first case of foreigners being seized in the mostly Muslim north of Cameroon, a former French colony, and highlighted the threat to French interests in West Africa since Paris deployed thousands of troops to Mali to oust al Qaeda-linked Islamists who controlled the country's north.

But the region - like others in West and North Africa with porous borders - is considered within the operational sphere of Boko Haram and fellow Nigerian Islamist militants Ansaru.

On Sunday, seven foreigners were snatched from the compound of Lebanese construction company Setraco in northern Nigeria's Bauchi state, and Ansaru took responsibility.

Northern Nigeria increasingly is afflicted by attacks and kidnappings by Islamist militants. Ansaru, which rose to prominence only in recent months, has claimed the abduction in December of a French national who is still missing.

Three foreigners were killed in two failed rescue attempts last year after being kidnapped in northern Nigeria and Ansaru, blamed for those kidnaps, warned this could happen again.

"Staging a successful rescue is always difficult, but even more so if the kidnappers are waiting for it," said Peter Sharwood-Smith, Nigeria country manager of security firm Drum Cussac.

"After the death of three European hostages in rescue-intervention attempts last year, Nigeria and France will be hoping for a peaceful resolution. The problem could be the kidnappers lack of enthusiasm for negotiation or deals. The fact that four of the hostages are children adds further difficulty to the decision for France and Nigeria."

The kidnapping in Cameroon brought to 15 the number of French citizens being held in West Africa.

Olympics: US, Iran unite in bid to keep wrestling in Olympics

TEHRAN: The United States and Iran may be arch foes on the diplomatic front, but bosses from two of wrestling's power-houses have allied to fight a decision to drop the sport from the 2020 Olympic Games.

Rich Bender, executive director of USA Wrestling, is in Tehran, which is hosting the World Cup men's freestyle tournament on Thursday and Friday.

"We need the backing of Iran and Russia... to preserve the wrestling, and this goes beyond politics... Iran is one of the powers in wrestling and can defend the game's credibility," he was quoted by the ISNA news agency as saying.

Speaking at a ceremony hosted by the Iranian Wrestling Federation, he said he hoped that, with the "comprehensive unity" among the wrestling power-houses, the IOC will change its decision.

The head of the Iranian Wrestling Federation, Hojatollah Khatib, said he hopes that "this unprecedented unity" can change the International Olympic Committee's decision.

Hegedus Csaba, a member of the International Federation of Associated Wrestling Styles (FILA), said "we are showing the IOC that we are united and will force them to bring back the wrestling to the Olympics.

"I am very happy that Khatib and Bender had very friendly meeting. This shows that we have a common language and that is wrestling."

Last week, the IOC's executive board voted to drop wrestling as one of the core sports of the games. That means it now joins seven others -- baseball/softball, karate, squash, roller sports, sport climbing, wakeboarding and wushu -- vying to be selected as an "additional sport."

The board will meet in May to consider presentations by their supporters and choose one to recommend to the full committee for a decision in September.

But the full committee is seen as unlikely to vote against the executive board, raising the prospect that one of the few sports that survived from the original Olympics in ancient Greece into the modern era will disappear.

The sport first appeared in 708 BC and has only ever been left out of the Olympic programme once before in 1900.

FILA has vowed to fight the decision, and International Olympic Academy president Isidoros Kouvelos also called on the IOC to respect the historical roots of the Olympics and not remove wrestling.

Wrestling-mad Iran was one of the first nations to criticise the move to scrap the sport, dubbing it a "big blow" to the country's sport which has been medal winner for the country.

Wrestling has an ancient history in Iran, dating a time when Persian kings would battle their opponents in epic matches. The sport attracts millions of followers across the country, and unofficial figures say tens of thousands actually go to the mats.

However, wrestling is forbidden for women in Islamic Iran.

Washington broke off relations with Iran in 1980 in the aftermath of the storming of the US embassy in Tehran that led to 52 American diplomats being taken hostage by Islamist students.

Since then, the US has been vilified by the Islamic republic as the "Great Satan."

It is particularly significant that public figures from the United States and Iran have come together with a common goal, given that the two countries' governments are locked in a tense showdown over an array of issues.

The United States, along with much of the West and Israel, suspects that Iran's civil nuclear programme is a cover for developing a bomb.

Tehran strongly denies that, but has been slapped with a host of sanctions aimed at pushing it to stop enriching uranium which, in highly pure form, can be used as the core of a bomb.

Washington is also at loggerheads over its support for the embattled regime of Syrian President Bashar al-Assad and for Hezbollah, the powerful Lebanese Shiite movement that is an arch-foe of close US ally Syria.

BJP will solve Indo-Naga problem if NDA comes to power: Rajnath Singh

DIMAPUR: The BJP reiterated that it would work towards solving the Indo-Naga problem if the BJP-led NDA government comes to power at the Centre. Talking to mediapersons at Dimapur Airport on Tuesday, national BJP president Rajnath Singh said that for decades Nagaland witnessed violence and turmoil and it was only after the AtalBihariVajpayee-led NDA government came to power at the Centre that positive steps were taken to restore peace and normalcy in the state.

Singh, who addressed election rallies for BJP candidates at Tizit and Aboi constituencies under Mon District, expressed confidence that the BJP-led NDA would form the next government at the Centre. "We will resolve the Naga political problem through mutual dialogue and in a unique way," he said.

Stating that the BJP was concerned about the people of the northeast, Singh said the NDA government had constituted the ministry for Development of North East Region (DoNer) keeping these long-term objectives in mind. "BJP has an emotional relation with the northeast and we assure the people of the region that when BJP comes to power, we will provide a special package for the development of the region as was done during the regime of Atalji," he said.

Claiming that the people of Nagaland have understood the need to have a non-Congress government, the BJP president said they are willing to let the NPF-led DAN government form the next government as well.

He said he was very happy to see the people's response at Aboi and Tizit constituencies. "I have full confidence that DAN will come to power again in Nagaland," he said.

Singh said that the party has implemented 50 per cent reservation for women in all BJP ruled states and once the DAN government comes to power in the state, he would ensure that women get empowerment with 33 per cent reservation.

When asked to comment about the Monday seizure of cash, arms and ammunition from the home minister of Nagaland, Imkong L Imchen, who is also a candidate of the BJP's ally, Singh said "whoever is charged and prima facie case established will not be given any charge in the next DAN government. BJP has never compromised on the issue of corruption and will never do so," Singh quipped.

Charging the UPA government of various scams, the BJP president said that it is now involved in the helicopter scam. "The entire nation is ashamed of the helicopter scandal, and the UPA government has been rocked by one scandal after another," Singh said. On the Prime Minister's proposal for a debate on the issue, he said "debate is not a solution to corruption."

He said during the NDA regime, prices of essential commodities were controlled and the GDP stood at 9.5 per cent. Singh slammed the UPA government saying inflation was on the rise while fiscal management was also affected. He claimed that the national GDP stands at 5.2 per cent at present. Singh said under the UPA government, the value of rupee as compared to dollar has been decreasing.

Costlier robotic surgery soars for hysterectomies

CHICAGO (AP) — Robotic surgery is increasingly being used for women's hysterectomies, adding at least $2,000 to the cost without offering much benefit over less high-tech methods, a study found.

The technique was used in just 0.5 percent of operations studied in 2007, but that soared to almost 10 percent by early 2010. Columbia University researchers analyzed data on more than 260,000 women who had their wombs removed at 441 U.S. hospitals for reasons other than cancer. The database covered surgeries performed through the first few months of 2010.

Women who had the robotic operations were slightly less likely to spend more than two days in the hospital, but hospital stays were shorter than that for most women. Also, complications were equally rare among robotic surgery patients and those who had more conventional surgeries. Average costs for robotic hysterectomies totaled nearly $9,000, versus about $3,000 for the least expensive method, a different type of minimally invasive technique using more conventional surgery methods.

Traditionally hysterectomies were done by removing the womb through a large abdominal incision. Newer methods include removing the uterus through the vagina and minimally invasive "keyhole" abdominal operations using more conventional surgery methods, or surgeon-controlled robotic devices.

Robotic operations involve computer-controlled long, thin robot-like "arms" equipped with tiny surgery instruments. Surgeons operate the computer and can see inside the body on the computer screen, through a tiny camera attached to the robotic arms. The initial idea was for surgeons to do these operations miles away from the operating room, but robotic operations now are mostly done with the surgeon in the same room as the patient.

Theoretically, robotic surgeries make it easier to maneuver inside the patient, and are increasingly used for many types of operations, not just hysterectomies.

The main explanation for the big increase "is that robotic surgery has been marketed extensively to not only hospitals and physicians, but also directly to patients. There is minimal data in gynecology that it is advantageous," said Dr. Jason Wright, an assistant professor of women's health and the study's lead author.

The study was published Tuesday in the Journal of the American Medical Association.

"Our findings highlight the importance of developing rational strategies to implement new surgical technologies," the researchers wrote.

They note that 1 in 9 U.S. women will undergo a hysterectomy, usually after the age of 40. Reasons include fibroids and other non-cancerous growths, abnormal bleeding, and cancer.

Traditional abdominal operations remain common and more than 40 percent of women studied had them, costing on average about $6,600.

A JAMA editorial says the study doesn't answer whether the robotic method might be better for certain women, and says more research comparing methods is needed. Still, it says doctors and hospitals have a duty to inform patients about costs of different surgery options.

Dr. Myriam Curet of manufacturer Intuitive Surgical of Sunnyvale, Calif., said surgical robots can help surgeons overcome the limitations of other minimally invasive methods for very overweight patients, those with scarring from other surgeries and other complexities.

Fiery Debate Over Pistorius' Story at Bail Hearing

As prosecutors today outlined their case against South African Olympian Oscar Pistorius, providing details that they say indicates a premeditated act of murder against his girlfriend, his lawyers swatted at each bit of evidence on the dramatic second day of a bail hearing that will likely foreshadow the upcoming trial.

The Johannesburg courtroom sat riveted as police investigators said that Pistorius, a double-amputee who gained global acclaim for racing at the 2012 London Olympics, shot his girlfriend through a closed bathroom door at a high angle from which he had to be wearing his prosthetic legs.

Prosecutors insisted that Pistorius took a moment to put the legs on, indicating that he thought out and planned to kill Reeva Steenkamp, his model girlfriend, when he shot her three times through a closed bathroom door early on the morning of Valentine's Day.

There was a "deliberate aiming of shots at the toilet from about 1.5 meters [about 5 feet]," prosecutor Gerrie Nel said.

Read Oscar Pistorius' Full Statement to the Court

Nel said Pistorius fired four shots into the bathroom, hitting Steenkamp three times in the head, elbow, and hip.

Nel also said a witness would testify to hearing "non-stop talking, like shouting" in the early hours before the dawn shooting.

Pistorius' lawyer, who argued Tuesday that the runner accidently fired on Steenkamp believing she was an intruder, assailed each bit of the prosecution's evidence, even getting a lead investigator to concede that police had not found anything to conclusively disprove the Olympian's story.

"[The angle] seems to me down. Fired down," Police officer Hilton Botha told the court, suggesting Pistorius was standing high up on his fake legs.

But when pushed by defense lawyer Barry Roux, Botha admitted he did not know whether Pistorius was wearing the prosthetics.

When asked about the witness who allegedly heard yelling between Pistorius and Steenkamp, Botha admitted under cross-examination that the woman was about 600 yards -- six football fields -- away at the time.

When the prosecutor questioned Botha a second time, he backtracked to say the witness was actually much closer.

The prosecution showed a floor-plan of the couple's apartment and said there was no way for Pistorius to cross from one side of the bedroom toward the bathroom, or retrieve his hidden pistol, without realizing Steenkamp was not in bed.

"There's no other way of getting there," prosecutor Nel said.

The defense further suggested that Steenkamp had gone to the bathroom on her own, and not to flee from Pistorius, because her bladder was empty. Had she simply run there to hide at 3 am, it would have more likely been full, Roux said.

Asked by defense attorney Roux whether Steenkamp's body showed "any pattern of defensive wounds," suggesting she had put up a fight, Botha admitted it did not.

Prosecutors also said that they found two boxes of testosterone and needles in the bedroom, although the defense disputed the finding, calling the substance a "herbal remedy," not banned drugs or steroids.

Botha told the court today that he arrived at Pistorius' home at 4:15 a.m., Feb. 14, to find Steenkamp already dead, dressed in a white shorts and a black vest, and covered in towels. The first thing Pistorius told police was that "he thought it was a burglar," officials said.

Bulgarian government resigns amid growing protests

SOFIA (Reuters) - Bulgaria's government resigned on Wednesday after mass protests against high power prices and falling living standards, joining a long list of European administrations felled by austerity during four years of debt crisis.

Prime Minister Boiko Borisov, an ex-bodyguard who took power in 2009 on pledges to root out graft and raise incomes in the European Union's poorest member, faces a tough task of propping up eroding support ahead of an expected early election.

Wage and pension freezes and tax hikes have bitten deep in a country where earnings are less than half the EU average and tens of thousands of Bulgarians have rallied in protests that have turned violent, chanting "Mafia" and "Resign".

Moves by Borisov on Tuesday to blame foreign utility companies for the rise in the cost of heating homes was to no avail and an eleventh day of marches saw 15 people hospitalized and 25 arrested in clashes with police.

"My decision to resign will not be changed under any circumstances. I do not build roads so that blood is shed on them," said Borisov, who began his career guarding the Black Sea state's communist dictator Todor Zhivkov.

A karate black belt, Borisov has cultivated a Putin-like "can-do" image since he entered politics as Sofia mayor in 2005 and would connect with voters by showing up on the capital's rutted streets to oversee the repair of pot-holes.

But critics say he has often skirted due process, sometimes to the benefit of those close to him, and his swift policy U-turns have wounded the public's trust.

The spark for the protests was high electricity bills, after the government raised prices by 13 percent last July. But it quickly spilled over into wider frustration with Borisov and political elites with perceived links to shadowy businesses.

"He made my day," said student Borislav Hadzhiev in central Sofia, commenting on Borisov's resignation. "The truth is that we're living in an extremely poor country."

POLLS, PRICES

The prime minister's final desperate moves on Tuesday included cutting power prices and risking a diplomatic row with the Czech Republic by punishing companies including CEZ, moves which conflicted with EU norms on protection of investors and due process.

CEZ officials were hopeful on Wednesday that it would be able to avoid losing its distribution license after all and officials from the Bulgarian regulator said the company would not be punished if it dealt with breaches of procedure.

But shares in what is central Europe's largest publicly-listed company fell another 1 percent on Wednesday.

If pushed through, the fines for CEZ and two other foreign-owned firms will not encourage other investors in Bulgaria, who already have to navigate complicated bureaucracy and widespread corruption and organized crime to take advantage of Bulgaria's 10-percent flat tax rate.

Financial markets reacted negatively to the turbulence on Wednesday. The cost of insuring Bulgaria's debt rose to a three-month high and debt yields rose some 15 basis points, though the country's low deficit of 0.5 percent of gross domestic product means there is little risk to the lev currency's peg against the euro.

Borisov's interior minister indicated that elections originally planned for July would probably be pulled forward by saying that his rightist GERB party would not take part in talks to form a new government.

MILLIONS GONE

GERB's woes have echoes in another ex-communist EU member, Slovenia, where demonstrators have taken to the streets and added pressure to a crumbling conservative government.

A small crowd gathered in support of Borisov outside Sofia's parliament, which is expected to approve his resignation on Thursday, while bigger demonstrations against the premier were expected in the evening.

Unemployment in the country of 7.3 million is far from the highs hit in the decade after the end of communism but remains at 11.9 percent. Average salaries are stuck at around 800 levs ($550) a month and millions have emigrated, leaving swathes of the country depopulated and little hope for those who remain.

GERB's popularity has held up well and it still led in the latest polls before protests grew in size last weekend, but analysts say the opposition Socialists should draw strength from the demonstrations.

The leftists, successors to Bulgaria's communist party, have proposed tax cuts and wage hikes and are likely to raise questions about public finances if elected.

Tennis: Kvitova eyes revenge match with Radwanska

DUBAI: Petra Kvitova, the former Wimbledon champion from the Czech Republic, continued her exciting return to form here on Wednesday with a performance which edged her nearer the tenth title of her career.

Kvitova's brilliantly masked hitting eased her into the quarter-finals of the $2,000,000 Dubai Open with a 7-5, 7-6 (7/1) win over Ana Ivanovic, the former French Open champion from Serbia.

It sets her up with a last eight match against Agnieszka Radwanska, the defending champion, and who she has painful memories of as the Pole beat her in the end of year Istanbul tournament last year.

Kvitova's match was full of fine ground strokes between two players who are gradually regaining some of their former excellence after fitness problems.

It lurched unpredictably, first one way and then the other.

Kvitova led 5-1 in the first set and 5-3 in the second and both times Ivanovic increased her ratio of early attacks and worked her way back to parity.

However Kvitova's outstanding facility for disguise tipped the balance.

"From the forehand I can think about going for every point a hundred percent and make winners from that side," she said.

Radwanska had to work hard to get past Yulia Putintseva, an 18-year-old wild card player from Kazakhstan, by 7-5 6-3.

Radwanska acknowledged the promise of her opponent.

"I really want to see her, you know, in a couple of months, how she's gonna play and what her ranking is going to be," the world number four from Poland said.

Kvitova was not displeased with this quarter-final draw.

"I played her last time Istanbul and I lost to her," she said with a blunt look, which recalled that in the process she also lost her WTA Championship season-end title.

"I'm looking for revenge, for sure."

Both players title hopes were boosted after the withdrawal of world number one Serena Williams earlier on Wednesday with a back injury. This followed Monday's withdrawal of top-seeded Victoria Azarenka with a heel injury.

Another reason for Kvitova's fine form, which saw her lead Williams 4-1 in the final set in Doha last week, is the improvement in her physical fitness compared with last year.

"I changed my fitness coach," she says.

"So it's different exercises, and working on different muscles. I have to get used to that and continue with it and to show it on the court then."

Another who might capitalise on the absence of the top two is Caroline Wozniacki, the former world number one from Denmark who won the title here two years ago.

She also looked in good form as she overwhelmed Zheng Jie, the former Wimbledon semi-finalist from China, by 6-0, 6-1.

Wozniacki looks fitter too and is trying to reproduce the movement and consistency which got her to the top in 2010 and 2011.

She was asked to explain the curiosity of her father-coach Piotr coming on to court to offer advice despite her rampant first set performance.

"It's just because we practise a lot of things," said Wozniacki. "He gives me some pointers, about what I need to remember, what we have practiced, and what can still be improved.

"It doesn't matter if you win 6-0 or 6-3, at the end of the day you want to win but you also want to try a few of the things that you have been practising."

Wozniacki next plays Marion Bartoli, the former Wimbledon finalist from France, who enjoyed her second piece of rare luck in this tournament by receiving a walk-over from Williams.

Bartoli was earlier given a wild card into the tournament after submitting her entry late.
