A case was registered against troopers of the Rashtriya Rifles for a shootout in Jammu and Kashmir's Sopore town Saturday that killed two civilians. The town remained tense Sunday as authorities imposed strict restrictions to prevent protests, officials said.

"An FIR has been lodged in the Sopore police station against troopers of 22 Rashtriya Rifles allegedly involved in the unprovoked firing on a group of youth in which two were killed and another critically wounded," a police officer said here.

Heavy deployment of police and paramilitary central reserve police force (CRPF) was made in Sopore, 50 km from here, in the wake of the indiscriminate firing by unidentified assailants in army uniforms.
