An Islamic opposition coalition in Pakistan plans to hold a nationwide strike on Saturday hoping to force President Pervez Musharraf to resign. The six-party United Action Forum has accused General Musharraf of serving the interests of the United States instead of the Pakistani people. Police have arrested hundreds of alliance supporters ahead of the strike to prevent what authorities say would be the disruption of law and order. United Action Forum leaders have predicted a successful strike. But the Associated Press of Pakistan reports that a federation of Pakistani chambers of commerce will boycott the strike. The federation says the work stoppage is not in the national interest and would discourage foreign investors.
