An army spokesman says a soldier in Indian-run Kashmir has opened fire on his own unit, killing four fellow soldiers and wounding one other.
Indian army spokesman Lt. Col. J.S. Brar says the man sprayed his unit with automatic weapon gunfire Thursday morning. He was later arrested.
The soldiers were part of an anti-insurgency unit in Punjpora, a village 28 miles (45 kilometers) south of the region's main city of Srinagar.
The state has been swarming with Indian soldiers since the start of a separatist rebellion in 1989 seeking the region's independence from India or merger with Pakistan.
There have been similar incidents in the past attributed to the stressful conditions the troops work under, including long hours under extreme weather conditions.
