A remote-controlled bomb exploded on Monday in the Pakistani city of Karachi, killing a paramilitary soldier and injuring eight other people, police said. The device, planted next to a security services vehicle, also injured six other people who happened to be in the area, according to Karachi police officials. Last June, the BLA took responsibility for an attack on the Pakistan Stock Exchange, also in the city of Karachi, where four militants armed with guns and grenades killed two guards and a policemen before security forces killed them.
