The security forces had surrounded a large forest area in Kupwara district on last Friday following reports that a group of heavily armed guerrillas was hiding inside the forest after infiltrating into Indian territory from across the line of control (LoC).
Two Rashtriya Rifles soldiers were injured on Friday in the security operation against the guerrillas. One soldier of the territorial army was also injured in the operation.
