Gunmen disguised as cops kill 13 in southwest Pakistan after pulling them off convoy of buses

QUETTA, Pakistan - Dozens of gunmen disguised in police uniforms shot to death 13 people they pulled off of a convoy of buses in southwest Pakistan and dumped their bodies in a nearby ravine, officials said Tuesday. The motive for the attack Monday night was unclear since no one has claimed responsibility. But suspicion may fall on separatists who have been waging a low-level insurgency in southwest Baluchistan province for decades.
