Some passengers who were travelling in two buses from the western Pakistani city of Quetta to Karachi on the southern coast were forced off midway in their journey in the town of Mastung, around 40 km south of Quetta by a group of armed men who were wearing the uniforms of the security forces. At least 19 of them were killed. It is reported that around 25 passengers were taken off two buses but bodies of 19 passengers had been found so far in nearby hills. So, an operation began to find the rest. It is however not clear whether they too have been killed or not. The motives of the assailants still remain unclear.
