Local police said a suicide bomber rammed his explosives-laden vehicle into a police station in northwest Pakistan, killing six people in the blast.
Police official Habib Khan said police and civilians were among the dead Thursday in Kohat district, an area close to the terrorist-riddled tribal regions. Some 20 people were wounded.
Pakistan has suffered a string of suicide attacks in the past two weeks that have killed more than 100 people.
The Taliban have claimed responsibility for most of the assaults and warned of more if the army proceeds with an offensive in their main stronghold in South Waziristan tribal region.
