Officials say US drone strike kills 4 suspected militants in tribal region near Afghan border

Intelligence officials in Pakistan say a U.S. drone strike has killed four suspected militants in a northwestern tribal region along the Afghan border.

The two officials and three local Taliban fighters say the strike Sunday killed two Arab militants and two of their local allies in a compound in the town of Wana in South Waziristan.

All the officials spoke on condition of anonymity because they were not authorized to talk to journalists. Authorities don't allow journalists into Pakistan's tribal areas, which have long been a safe haven for militants.

Pakistan's army largely cleared militants from South Waziristan in a 2009 operation. Soldiers now are fighting militants in North Waziristan in an operation that began in June.

U.S. drone strikes are widely unpopular among many in Pakistan.
