QUETTA, Pakistan - Gunmen disguised as members of the Pakistani security forces killed at least 20 passengers late on Friday after forcing them off buses travelling from the western city of Quetta to Karachi on the southern coast, officials said.
The assault in the restive province of Baluchistan occurred in the town of Mastung, around 40 km south of Quetta.
"Fifteen to 20 armed men in three pickup trucks and wearing security uniforms kidnapped around 35 passengers," Sarfaraz Bugti, Baluchistan's home minister, told Reuters.
He said the bodies of 20 passengers were later found around two km away from the main Quetta-Karachi highway in nearby foothills.
The circumstances of their deaths could not immediately be established, and the motives of the assailants were unclear.
