US spy drones fired missiles early Thursday into a school set up by a top Taliban commander in a tribal area bordering Afghanistan, killing 11 people.
"At 2:25 am, two spy drones fired three missiles at the madrassa of Mullah Mansoor. Eleven people have been killed in the missile strike" security officials said.
The air strike apparently targeting veteran militant Jalaluddin Haqqani, a major target for US forces, was the latest in a string of attacks on Pakistani soil that have raised tensions between Islamabad and Washington.
Haqqani was one of the most prominent Afghan commanders who fought the Red Army between 1978 and 1989. He subsequently became close to Mullah Omar, the leader of the 1996-2001 Taliban regime in Afghanistan.
Since the fall of the Taliban, Haqqani has become one of the most active Taliban commanders launching attacks on international forces in Afghanistan from safe havens in Pakistan, security officials said.
