An explosive device has killed five Pakistani soldiers in the country’s southwest, the army said. The troops died during an operation on Saturday in Kech District, Baluchistan province, when suspected militants detonated the improvised device on the security forces’ vehicle. The ensuing gunfight killed three “terrorists,” the army said. A clean-up operation was carried out to eliminate any other militants found in the area, it added. The soldiers were aged between 23 and 25. Nobody immediately claimed responsibility for the attack.
