Four boys were killed while playing with an abandoned explosive device that went off in a town in north west Pakistan.
The children were playing near a pond in the garrison town of Kohat with what officials describe as a “shell”, apparently from a mortar. It appeared to be an accident.
Islamist and criminal gangs are active in the Kohat region, and all sorts of weapons, including land-mines and grenades, can be found in the area.
Kohat also lies near the tribal regions bordering Afghanistan, where al Qaida and Taliban fighters have bases.
