Police killed two suspected terror recruiters in a gunbattle at a boys school after hearing they were trying to sign up students for suicide bombings and holy war, officials said. One police officer was killed by a hand grenade during the brief clash. Three suspected militants turned up at the privately run Oxford Public School in Tank, a town in northwestern Pakistan about 100 kilometers from the Afghan border, on Monday morning, local police chief Mumtaz Khan said. "We heard that they were looking for children to prepare them for jihad and for suicide attacks," Khan told The Associated Press. No students were hurt in the clash. The school, which teaches English to boys between the ages of 5 and 17, was closed when a reporter visited later Monday and its administrators could not be reached for comment.
