Gunmen in Pakistan took hundreds of students and teachers hostage on Tuesday in a school in the northwestern city of Peshawar, military officials at the scene said.
Reuters reported that the Taliban claimed responsibility for the attack.
A Reuters journalist at the scene could hear heavy gunfire from inside the school as soldiers surrounded it.
Military officials said at least six armed men had entered the military-run Army Public School. About 500 students and teachers were believed to be inside.
