Benazir Bhutto died from bullet wound, Interior Ministry says

RAWALPINDI, Pakistan (CNN) - Former Pakistan Prime Minister Benazir Bhutto was assassinated Thursday outside a large gathering of her supporters by a suicide bomber who also killed at least 22 of those supporters, doctors and a spokesman for her party said.

Bhutto died of a gunshot wound to the neck, the Pakistani Interior Ministry said. The attacker fired shots and then blew himself up, the ministry told the Associated Press of Pakistan.

An eyewitness, John Moore, said Bhutto was standing through the sunroof of her vehicle, waving to supporters, when two shots rang out. Bhutto fell back into the vehicle, and almost immediately a bomb blast rocked the scene, sending twisting metal and shrapnel into the crowd, said Moore, a photographer with Getty Images.

President Pervez Musharraf, after an emergency meeting of his government's top officials, told his nation that the attack was "the work of those very same people with whom we are waging a war. Pakistan's biggest threat comes from these terrorists."
