Police and security forces are on the job," police said.Earlier in the day, an encounter broke out in Jammu district.Four terrorists belonging to Pakistan-based Jaish-e-Mohammed terror group were killed in the gunfight in Jammu's Nagrota area. They were travelling in a truck on the Jammu-Srinagar National Highway, which was intercepted by the police at a toll plaza near Nagrota.The slain terrorists were carrying a huge quantity of arms and ammunition, including 11 AK-47 rifles and pistols and in all probability were planning something big, perhaps "disruption of district-level elections", a top police officer said.
