The death of the 54-year-old charismatic former prime minister threw the campaign for Pakistan’s Jan. 8 parliamentary elections into chaos and created fears of mass protests and violence across the nuclear-armed nation, an important U.S. ally in the war on terrorism.

The attacker struck just minutes after Bhutto addressed thousands of supporters in the garrison city of Rawalpindi, 8 miles south of Islamabad. She was shot in the neck and chest by the attacker, who then blew himself up, said Rehman Malik, Bhutto’s security adviser.

Bhutto was rushed to the hospital and taken into emergency surgery.

“At 6:16 p.m., she expired,” said Wasif Ali Khan, a member of Bhutto’s party who was at Rawalpindi General Hospital.

“The surgeons confirmed that she has been martyred,” Bhutto’s lawyer Babar Awan said.
