Four people were killed and five were wounded during violence Friday in Indian-administered Kashmir, a paramilitary official said. Security forces shot and killed two militants during an encounter Friday in the Sopore area, about 55 kilometers, or more than 33 miles, from Srinagar, the region's capital. The forces returning from the incident were stoned by a mob, which also torched a security vehicle, according to a report of the Associated Press. Troopers then fired to disperse the mob, killing two people and wounding five others. "They attacked and torched our vehicle. Our personnel opened fire in self-defense," said Prabhakar Tripathi, a spokesman for India's paramilitary unit, the Central Reserve Police Force. Authorities imposed a curfew, and troops and police were deployed to the area to defuse tensions.
