Provincial police spokesman Khali Aseir said today that a large number of Taliban fighters assaulted the outpost overnight.
He says the members of the local police were ambushed and killed while on their way to the outpost to assist the Afghan soldiers in the remote district of Khwaja Ghar.
The soldiers suffered no casualties.
Taliban spokesman Zabihullah Mujahid claimed responsibility for the assault late yesterday and the police slayings.
He claimed the Taliban had inflicted a far higher number of casualties but the insurgents often exaggerate their claims.
