A bomb blast targeting a pro-government tribal elder has killed six people in northwest Pakistan.

Police officer Fazal Naeem Khan said it was unclear whether the elder, Malik Habibullah Khan, was among those killed in the attack on Monday, but his vehicle was damaged. The explosion in Hangu district of Khyber Pakhtunkhwa province also injured 10 people.

No one has claimed responsibility for the attack, but suspicion likely will fall on the Pakistani Taliban.

The Pakistan Government has encouraged tribesmen in the northwest to form militias to fight against the Taliban. The militants have carried out many retaliatory attacks against these groups.
