A Pakistani government official says a roadside bomb blast has killed three soldiers in a northwestern tribal region near the Afghan border.
Javed Khan, a local administrator in the Kurram tribal area, says another soldier was wounded by the explosion near an army vehicle in Dogar village on Monday.
No one has claimed responsibility. The Pakistani Taliban often attack soldiers deployed in the tribal region to fight local militants and their foreign allies.
The Pakistani Taliban have waged a bloody insurgency in the country in recent years that has killed thousands of soldiers.
