A suicide bomber on Tuesday rammed his explosive-laden car into a checkpoint outside a police station in northwestern Pakistan, wounding six people, police said.
The attack took place at a police station outside the restive town of Bannu bordering the lawless tribal regions where Taliban and Al Qaeda linked militants are known to operate.
The blast damaged the outer wall of the police station and two houses near the checkpoint, he said.
Taliban militants immediately claimed responsibility for the attack.
Suicide and bomb attacks blamed on Islamist insurgents have killed more than 5,200 people across nuclear-armed Pakistan since July 2007.
