KARACHI, Pakistan

Suspected militants killed at least seven people in an armed attack on the office of a local "peace militia" in northwest Pakistan, police said on Friday.

The attack occurred late Thursday night in the outskirts of the Bannu district of northwestern Khyber Pakhtunkhwa province.

Another two people were also injured in the attack.

No group has claimed responsibility for the attack. However, security forces pointed fingers at the Tehreek-Taliban Pakistan (TTP), a consortium of several militant groups operating in the country, which has long been operative in Bannu and its adjoining areas, including the North Waziristan tribal district.

Prime Minister Shehbaz Sharif, in a statement, condemned the attack and directed the authorities to mobilize all available resources to bring the perpetrators to justice.
