Three federal police are dead and another was injured following a shooting at a barracks in insurgency-hit Kashmir, an official said on Sunday.The fatal incident happened late on Saturday evening inside the Central Reserve Police Force (CRPF) camp in the Himalayan town of Kulgam, about 90-minutes drive from Srinagar. “We have three CRPF personnel dead and one injured,” a police officer said, speaking on condition of anonymity because he was not authorised to speak with the media.Other personnel inside the barracks at the time of the shooting were detained for questioning, he added. It was not immediately clear if there was one or more shooters responsible for the deaths.Around 100 Indian security force personnel commit suicide every year in Kashmir and the insurgency-racked northeastern states, according to official figures.There have also been a raft of incidents involving soldiers shooting their comrades and officers, known as fragging, which have been blamed on stress.
