PESHAWAR, Pakistan — At least six foreign militants were believed to have been killed in an American drone strike in the North Waziristan tribal region on Sunday morning, a Pakistani security official said.

The Pakistani official said a drone fired two missiles into a compound in the Datta Khel subdistrict at 6:40 a.m. The area is close to the border with Afghanistan and to Miram Shah, the main town in North Waziristan and the site of the region’s administrative headquarters.

“The drone targeted a base of an Uzbek commander known as Usman, killing six Uzbek militants. Two militants are wounded,” the official said, speaking on the condition of anonymity because he was not authorized to talk to the news media.
