"Indian security forces launched a cordon and search operation in Kashmir's Shopian district early Sunday," Deputy Police Superintendent Yasir Qadri said. "Hiding militants opened fire at the troops, leading to gunfights which continued until late Sunday afternoon."
The operation resulted in violence between security forces and anti-government protesters who took to the streets. The unrest left four civilians dead, Director General of Police Shesh Paul Vaid said on twitter.
