Islamabad, Aug 7 - Pakistan Taliban chief Baitullah Mehsud, who is said to be responsible for the assassination of former prime minister Benazir Bhutto, was killed in a drone attack in Waziristan Wednesday, Foreign Minister Shah Mahmood Qureshi confirmed Friday.

'He (Mehsud) has been taken out,' Qureshi told reporters here.

He however said that the government was doing ground verification so as 'to confirm 100 percent', Dawn reported Friday.

Qureshi said intelligence sources have confirmed Mehsud's death.

Intelligence officials said Mehsud was killed in a missile strike Wednesday on the home of his father-in-law and that his body was buried in the village of Nardusai in South Waziristan, not far from the site of the strike, the report said.

One official said he had seen a classified intelligence report stating Mehsud was dead and buried, but that agents had not seen the body as the area was under Taliban control.

Interior Minister Rehman Malik earlier said he could confirm the death of Mehsud's wife but not of the Taliban leader himself, although information pointed in that direction.

'I can confirm to the extent that his wife is dead, and probably one of his brothers, but we do not have any...evidence that he's dead,' Malik was quoted as saying.

He added: 'Yes, lot of information is pouring in from that area that he's dead, but I'm unable to confirm unless I have solid evidence.'

Dawn quoted a local tribesman as saying that Mehsud had been at his father-in-law's house being treated for kidney pain, and had been put on a drip by a doctor, when the missile struck. The tribesman claimed he attended the Taliban chief's funeral.
