AK-47 rifles, hand grenades, magazines and other explosive material have been recovered, the police said, adding that the equipment indicated that they had come for a long siege.

Sindh's Governor Imran Ismail condemned the incident. "Strongly condemn the attack on PSX aimed at tarnishing our relentless war on terror.
