Intelligence officials say a suspected U.S. drone missile strike has killed six militants in Pakistan's lawless tribal area near the Afghan border.

It was the third such attack in the past 24 hours in an area of North Waziristan controlled by a militant commander who has targeted coalition troops in Afghanistan.

The officials say the suspected U.S. drone fired three missiles at a house in the Pai Khel area of North Waziristan on Friday, killing the three militants and wounding two others.

The officials spoke on condition of anonymity because they were not authorized to talk to the media.
