Pakistan President Pervez Musharraf now says opposition leader Benazir Bhutto may have been shot, changing the government's earlier story that she died after hitting her head on her car's sunroof during a suicide bomb attack.

In an interview for the CBS television program 60 Minutes that is to air Sunday evening, Musharraf said investigators may have jumped to conclusions.

Asked if Bhutto might have been shot, he answered, "Yes, absolutely, yes. Possibility."

Bhutto was killed after leaving a campaign rally in the northern city of Rawalpindi on Dec. 27.

Her Pakistan Peoples Party (PPP) has disputed the official version of Bhutto's death — that she hit her head on the lever of her car's sunroof, because she was trying to duck into the vehicle while she was jolted by the force of the explosion set off by a lone assassin.

The PPP said video footage appears to show Bhutto being shot by a man at close range seconds before he set off a bomb.

Bhutto's husband has accused members of Pakistan's ruling regime of involvement in his wife's killing, and has called for a United Nations investigation.

On Saturday, five police officers from Britain's Scotland Yard visited the crime scene, where another 20 people died in the suicide explosion. After three hours at the site, the team went to the local police station to talk to officers.

In the CBS interview, Musharraf said Bhutto herself is really to blame for what happened because she refused to take adequate safety precautions.

"For standing up outside the car, I think it was she to blame alone. Nobody else. Responsibility is hers," he said.
