Suspected U.S. missiles kill 4 militants in Pakistan

ISLAMABAD (Reuters) - A suspected U.S. drone aircraft fired missiles at house in Pakistan's Waziristani tribal region on Thursday, killing four Islamist militants a day after U.S. commandoes killed 20 people in a cross-border assault.

The latest attack targeted the house of a tribesman, Rehman Wali, in the Mohammad Khel area in North Waziristan tribal region, near the border with Afghanistan, where the militants were hiding.

"Apparently three missiles were fired by the drone," a witness in the area told Reuters on condition of anonymity. Five militants were wounded in the attack.

Military officials were not immediately available for comment and it was not known whether any senior al Qaeda leader was among those killed or wounded.

On Wednesday, U.S. forces carried out a pre-dawn helicopter-borne ground assault on the village of Angor Adda in the nearby South Waziristan tribal region in the first known incursion into Pakistan by U.S.-led troops since the invasion of Afghanistan in 2001.

The United States, a major source of aid to nuclear-armed Pakistan, has not officially commented on the raid, though U.S. officials in Washington said the U.S. commandoes attacked an al Qaeda target in a move that could signal more intense U.S.-efforts to thwart cross-border militant violence.

North and South Waziristan are regarded as major sanctuaries for al Qaeda and Taliban militants.

Anger mounted in Pakistan, a staunch U.S. ally, after Wednesday's attack, with the foreign minister saying Pakistan was determined to defend its territorial integrity.
