Reports on the Kohat attack said an attacker rammed an explosives-laden vehicle into the mosque, after which how many armed gunmen attempted to storm the police compound?

Explanation: Reports described around seven armed gunmen attempting to enter the Kohat police compound after the initial vehicle bomb detonated at the adjoining mosque, exchanging fire with officers before security forces killed six of them during the initial engagement, with one suicide bomber separately attacking the nearby office of an intelligence agency. The multi-pronged nature of the assault, combining a vehicle bomb, armed infiltration and a secondary suicide attack, reflects a level of coordination consistent with significant advance planning.
