A police compound in Tehsil Bara of Khyber district was attacked by terrorists on Thursday.

The attack left four policeman martyred and eight others injured.

KP IGP Akhtar Hayat told journalists that two suicide bombers attacked the computer, one from the front gate and the other from the rear. They were gunned down by the police guards, he said.
