At least 41 people were killed and 45 injured in a suicide car bombing in the north-western Shangla district of Pakistan Monday. Six security personnel were among the dead. The attack, which targeted an army vehicle, is the latest in a string of attacks in advance of Pakistan's expected offensive of the Taliban and al Qaeda stronghold of South Waizirstan. Meanwhile, the Taliban claimed credit for the audacious weekend siege of the Pakistani army's headquarters. A Taliban spokesman called the Associated Press to say that the weekend attack, which killed 20, is the first of a planned series aimed at avenging former leader Baitullah Mehsud, who was killed by a U.S. drone.
