At least 12 militants have been killed and eight others injured in a suicide attack in Pakistan's northwestern district of Hangu, when the bomber rammed his explosive laden vehicle into the central building of Mullah Nabi Hanfi militant group.
It is unclear if the leader of militant group has been also killed in the attack.
According to reports, no official rescue services were offered as the exact location of the militants' center was unknown and sources said that the intensity of the blast indicated use of over 500 kilograms of explosives.
