"Bhutto Not Killed By Assassin's Bullet"

An Interior Ministry spokesman said a post mortem found no bullets or shrapnel in her body.

He was speaking at a press conference at which video was shown of Ms. Bhutto's last moments.

It is now believed that she was killed when she tried to duck back into the vehicle, and the shock waves from the blast knocked her head into a lever attached to the sunroof, fracturing her skull.
