Three labourers were killed after militants attacked a General Reserve Engineer Force camp in Jammu and Kashmir’s Akhnoor region late on Sunday. The incident took place after a group of three unidentified men attacked the camp, reported The Indian Express.

The militants are believed to have infiltrated the country from across the Line of Control with Pakistan. “At 1.15 am, there was attack on GREF platoon in Batla. Three labourers were killed. The area has been cordoned off as search operations are on,” Defence Public Relation Officer Manish Mehta told ANI.

The labourers killed in the attack worked with the authority that develops and maintains roads in border areas.

Authorities cordoned off the area after gunshots were heard. Akhnoor has been put on high since the strike. Schools and colleges in the subdivision have been asked to remain closed. Senior police officers are combing the spot.

The incident comes only weeks after the militant attack on an Army camp in Nagrota. Seven soldiers were killed in the incident on November 29.
