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.
The buses were headed to central Punjab province, and the separatists have a history of attacking Punjabis who they view as outsiders encroaching on their independence. The province is also home to many Islamic militants who have carried out attacks in the past, especially on minority Shiite Muslims.
Paramilitary troops provide protection for bus convoys moving through Baluchistan. But gunmen distracted the troops by shooting at a nearby oil tanker, said Kashif Nabi, a local government administrator.
