Violence erupted in several cities after Bhutto, 54, was shot in the neck and chest at a campaign rally in Rawalpindi Thursday afternoon. A homicide bomber then blew himself up, killing at least 20 others.
Bhutto's supporters erupted in anger and grief after her murder, attacking police and burning tires and election campaign posters in several cities. At the hospital where she died, some smashed glass and wailed, chanting slogans against President Pervez Musharraf.
The death of the charismatic former prime minister threw the campaign for the 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.
