A U.S. airstrike near Afghanistan's border with Pakistan killed the mastermind of a 2014 attack on a Pakistani school that killed some 150 people, mainly children, American and Pakistani officials said Wednesday. Pentagon press secretary Peter Cook said the airstrike Saturday killed "known terrorist leader" Umar Khalifa, who was known by several other names including Khalifa Umar Mansoor. It said the group is linked to the Pakistani Taliban and is based in Dara Adam Khiel, Pakistan. In his statement, Cook said the successful attack underscored what he called common security interests shared with Pakistan and Afghanistan. Cook said he was killed along with four other "enemy combatants" in an airstrike targeting members of an Islamic State (ISIS) affiliate known as Khorasan Province.
