SRINAGAR, Indian-controlled Kashmir, March 21 (Xinhua) -- A paramilitary troop of the Central Reserve Police Force (CRPF) killed three of his comrades and later shot and injured himself in restive Indian-controlled Kashmir, officials said Thursday.

The fratricide took place at a camp in Battal Ballian in Udhumpur, 203 km south of Srinagar city, the summer capital of Indian-controlled Kashmir.

"In this incident three of our personnel have died and the one who shot them is critically wounded," a CRPF officer, Harinder Kumar, told media. "These are preliminary details, we will come up with detailed information about the incident soon after investigation."

The shooting took place on Wednesday at 10:00 p.m. local time inside the camp allegedly over a disagreement on issues among the personnel, reports said.

Many incidents of suicides and fratricides among stationed troops across the region have been reported in the past.

Health experts said continued separation from family, long duty hours, lack of recreational facilities, poor command and control structure were usually found to be reasons behind such incidents.
