Police said the bomber dressed as a woman had tried to enter a Shia Hazara township in Quetta but the guard on duty tried to stop him which led to the attacker blowing himself up and killing the guard instantly while several people were injured.
This is not the first time that a suicide attack has been aimed inside the Hazara township which has houses of the minority Shia Hazara community.
Security sources claimed that the attacker had explosives strapped on his body which he detonated prematurely on being intercepted by the guard.
