More than 100 people have been killed in Pakistan after Taliban gunmen attacked a military-run school in Peshawar. The death toll has reached 126 with at least 84 believed to be children. The Taliban has said it targeted the children of military families in retaliation for Pakistan’s anti-Taliban campaign in North Waziristan. Since June, at the urging of the United States, Pakistan has waged a massive offensive in the region, which coincided with the resumption of U.S. drone strikes.
