A militant attack on a district police headquarters in Kohat, in Pakistan's Khyber Pakhtunkhwa province, has left at least 31 people dead and more than 100 injured, a senior police official said, with fighting still ongoing.

Attackers stormed the Old Police Lines complex in Kohat, a town of about 220,000 people in Pakistan's Khyber Pakhtunkhwa province, on Friday afternoon, according to a senior police official.
The compound serves as a district-level police headquarters and houses key offices of the Counter Terrorism Department, the Special Branch and several other police units.
The attack involved an explosion and gunfire. At least 31 people were killed, including 16 police personnel, and more than 100 were injured, the official said on Saturday, describing the toll as what had been counted so far.
Fighting was reported to be ongoing, with several militants still holed up in the Special Branch section of the Kohat police compound, the official said.
No claim of responsibility was reported in the accounts available, and further details on the attackers or the sequence of events were not immediately provided.
