Musharraf was also quoted as telling the CBS 60 Minutes programme to be broadcast on Sunday that his Government did everything it could to provide security for Bhutto, who was killed last week in a gun and suicide-bomb attack after a political rally.

"For standing up outside the car, I think it was she to blame alone. Nobody else. Responsibility is hers," Musharraf said in the interview taped on Saturday morning.

Pakistan's government has said Bhutto died when she struck her head on a handle on her vehicle's sunroof -- a contention widely derided in Pakistan where many people suspect Musharraf's Government of complicity. The Government has also blamed al Qaeda for the attack.

Musharraf was asked by CBS, which provided excerpts of the interview, whether a gunshot could have caused Bhutto's head injury. He replied, "Yes, yes."

The questioner asked, "So she may have been shot?" and Musharraf said, "Yes, absolutely, yes. Possibility."

Bhutto's widower called on Saturday for a UN investigation of the killing.
