An explosion went off shortly after Pakistani opposition leader Benazir Bhutto addressed a political rally in the garrison city of Rawalpindi, killing at least 20 people, witnesses said.
An Associated Press reporter at the scene could see body parts and flesh scattered at the back gate of the Liaqat Bagh park where Bhutto had spoken. He counted about 20 bodies, including police, and could see many other wounded people. (AP)
