At least five school children including three girls were killed when a toy bomb they were playing exploded in Pakistan-controlled Kashmir, local TV channels reported.
The blast occurred when the children found the device in a farm near their school in Neelum Valley, near the Line of Control (LoC) which divides Pakistan and India in the disputed Kashmir region, TV channels reported.
Reports said Pakistani soldiers were searching the farm to find any such devices.
Soldiers on both sides of the LoC had been involved for years in heavy exchange of fire but the Pakistan announced a unilateral ceasefire on the volatile Line of Control in Kashmir in late 2003. India had positively reciprocated and guns had been silent since then.
