The death toll from an attack on the police lines headquarters in Kohat, Khyber Pakhtunkhwa, rose to at least 31, with more than 100 people injured, according to the report. Military and police forces concluded a 22-hour standoff at the compound around noon on Saturday. The incident began on Friday with a suicide blast at the compound's perimeter gate. At least seven operatives from the Ittehad-ul-Mujahideen Pakistan (IMP) group then breached counter terrorism department (CTD) and intelligence facilities, the report said. Once inside, the operatives reached the facility's weapons depot, released many detained terror suspects, and armed some of them to fight Pakistani personnel, sources said. Heavy gunfire was exchanged through Friday night and Saturday despite a large deployment of security forces.
