A Pakistani official says a bomb planted on a railway track killed three passengers in a passing train and wounded seven others in the southwest.
Railways spokesman Maqbool Ahmed says the bombing in Baluchistan province early Sunday targeted a train bound for Rawalpindi, where the military is headquartered.
No one claimed responsibility, but separatist groups in the region have claimed similar attacks in the past. For over a decade, Baluchistan has been the scene of a low-intensity insurgency by ethnic Baluch separatists who want autonomy or outright independence.
