A mob of 150-200 people set ablaze two vehicles near the Kangla Fort here and also tried to snatch weapons from the police, forcing the security forces to fire at the crowd, sources said on Saturday. However, there were no reports of any casualties. Two columns of security personnel -- one each of the Army and the Assam Rifles -- moved to the general area of the Songdo village on Friday night to enforce the cessation of violence.
