Gunmen attacked a police checkpoint in northwest Pakistan at dawn on Friday, killing four policemen before speeding away in a getaway vehicle, police said.
The attackers sprayed bullets at policemen sheltering from rain inside a checkpost building in Ghazi Kot town inthe mountainous Mansehra district.
"Four policemen were killed on the spot. They were taking shelter inside the checkpost when rain started. One injured is still unconscious," Zulfiqar Jadoon, a police official told AFP by telephone from the scene. "This is a clear act of terrorism," Jadoon added. The gunmen arrived in a vehicle and fled after the attack.
An intelligence official confirmed the incident and blamed "miscreants", a term widely used by Pakistani officials in reference to Taliban and other Islamist militant networks.
A wave of suicide and bomb attacks across Pakistan has killed more than 3,300 people since 2007. Blame has fallen on Taliban and Al-Qaeda-linked militants bitterly opposed to the country's alliance with the United States. Mansehra is a relatively peaceful district in the highly volatile northwest, but militants armed with guns and grenades stormed offices of a US-based Christian charity in the district killing six aid workers in March.
