A militant who acted as a senior operations organizer for al Qaeda was targeted and killed in one of two U.S. drone strikes launched against targets inside Pakistan, a U.S. official said, according to Reuters.

U.S. and Pakistani sources said that the target of the attack was Aslam Awan, a Pakistani national from Abbottabad, the same town where Osama bin Laden was killed last May by a U.S. commando team. They said he was targeted in a strike by a U.S.-operated drone directed at what news reports said was a compound near the town of Miranshah in the border province of North Waziristan.

That strike broke an undeclared eight-week hiatus in attacks by the armed, unmanned drones that patrol Pakistan's tribal areas and are a key weapon in U.S. President Barack Obama's counter-terrorism strategy.

The sources described Awan, who also was known by the nom-de-guerre Abdullah Khorasani, as a significant figure in the remaining core leadership of al Qaeda, which U.S. officials say has been sharply reduced by the drone campaign. Most of the drone attacks are conducted as part of a clandestine CIA operation.

Pakistani officials could not confirm that Awan was killed in the drone attack, but the U.S. official said he was.
