Pakistan in turmoil

KARACHI, Pakistan, Oct. 21 (UPI) -- Supporters of former Pakistani Prime Minister Benazir Bhutto reportedly rampaged through Karachi, forcing shops to close.

Saturday's protests were sparked by last week's bombing of Bhutto's homecoming motorcade that killed more than 139 people celebrating her return from eight years of exile, CNN-IBC reported Sunday.

Police say as many as five people may have been responsible for the bombing, Dawn reported Saturday. The suicide bomber may have been part of a suspicious-looking group of men seen holding sticks, a senior police official told Dawn.

Bhutto blamed the bombing on supporters of Pakistan's late military ruler Mohammed Zia ul-Haq. Zia overthrew Bhutto's father, Prime Minister Zulfikar Ali Bhutto, in 1977 and had him hanged two years later. Zia died in a plane crash in 1988.
