Jammu, Feb 15 (IANS) Authorities on Friday imposed curfew in Jammu city after mobs protesting against the terrorist strike in the Kashmir Valley turned violent, torching some vehicles and damaging several others.

District Magistrate Ramesh Kumar said the curfew had been clamped to maintain law and order.

Police said the violence began in the city's Gujjar Nagar area.

Police used tear smoke and batons to bring the situation under control after which curfew was imposed, initially in Gujjar Nagar, Talab Khatikan, Janipur, Bakshi Nagar, Chenni Heemat, Bus Stand and some other places in old city area and later extended to entire Jammu.
