The Jamaat-ul-Ahrar militant group claimed responsibility for the attack. Four suicide bombers attempted to enter the camp at 6:20am and attacked a mosque in a residential area where a large number of soldiers were attending morning prayers. "Wearing suicide jackets, the attackers opened fire and tried to rush inside the mosque," the ISPR said in a statement. "Security forces surrounded the attackers. Two of the attackers blew themselves up while two others were shot dead," it added.
The attackers were contained in the outer courtyard of the mosque. A curfew was imposed on Mohmand Agency following the incursion as gunship helicopters searched the area. Mohmand is one of Pakistan's seven tribal agencies near the Afghan border where the military has been battling Al-Qaeda and Taliban-linked militants for over a decade. The army launched operation Zarb-e-Azb in June 2014 in a bid to wipe out militant bases in the north-western tribal areas. Security has since improved though scattered attacks still take place. In September this year, a suicide bomber targeted a mosque in Mohmand Agency's Anbar Tehsil during Friday prayers, leaving at least 24 people dead.
