Suicide attackers of the Pakistan-based JeM terror group stormed a BSF camp with guns and explosives near the Srinagar airport on Tuesday morning, leading to battles that left all three attackers and a trooper dead.
Four BSF troopers were injured and were taken to hospital.
The militants, dressed in military fatigues, broke into the 182 Battalion Border Security Force camp in Humhama area at around 4.30 a.m. The BSF camp shares a wall with an Air Force station and is located in a hilly region.
The attackers breached four layers of security in the highly-protected zone which houses many of Jammu and Kashmir's Who's Who.
This is the first militant attack in nearly 30 years so close to the airport.
Officials said the militants fired indiscriminately and threw grenades at security pickets before entering the BSF camp where most inmates were asleep. The airport closeby was yet to begin the day's operations.
Police said one of the attackers was shot dead first and the other two were killed later in an operation that lasted several hours. By then, the terrorists had killed BSF Assistant Sub-Inspector B.S. Yadav.
Flight operations at the airport were disrupted in the morning and the road leading it was sealed. Schools in the vicinity were ordered shut for the day.
