The U.S. report claimed that Pakistani forces had first fired at NATO forces in Afghanistan, which promoted air strikes by the U.S. fighter jets and helicopters.

Pakistani Prime Minister Yusuf Raza Gilani presided over the meeting of Defense Committee of the Cabinet (DCC) late Saturday which formally rejected the U.S. report.

Gilani said that regret expressed by the U.S. and NATO officials over the killing of 24 Pakistani soldiers was insufficient.

The DCC demanded apology from the U.S. and NATO over the deaths of Pakistani soldiers.

The meeting also renewed demand that the U.S. military stop drone strikes in Pakistan's northwestern tribal regions.
