Gunmen killed at least 19 passengers they had forced off buses travelling from the western Pakistani city of Quetta to Karachi on the southern coast, said the home minister for the restive province of Baluchistan, where the attack took place. The assault occurred late on Friday in the town of Mastung, around 40 km south of Quetta. “The armed men were wearing the uniforms of the security forces,” Sarfaraz Bugti told Reuters. The bodies of 19 passengers had been found so far, he said. Security officials said around 25 passengers were taken off two buses, and an operation began to find them. The bodies were discovered in nearby hills, the officials said.
