An advisory is being sent by the Home Ministry to all states asking them to beef up security in markets, religious sites, railway stations, bus terminus, bridges and all crowded places as Lashkar-e-Taiba or Indian Mujahideen terrorists may try to carry out attacks.
Official sources said the Centre has asked the states to deploy additional forces in sensitive locations and prevent any attempt by terrorists to carry out subversive activities.
Separate advisories have also been sent to Jammu and Kashmir, Assam and other northeastern states to be extra vigilant against Pakistan-based terrorist groups and insurgency groups respectively.
