India was put on high alert today following a series of terror attacks in France in which at least 120 people were killed and police and state governments have been asked to beef up security including at all foreign embassies and consulates.
Official sources said police had been asked to increase vigil and post additional police personnel outside all embassies and high commissions here and consulates in different cities across the country.
Security forces were also asked to keep a tight vigil at airports, railway stations, bus terminus, markets and religious places.
They said the step has been taken as a precautionary measure as terrorists of banned Lashker-e-Taiba (LeT) and Indian Mujahideen have been conspiring to target foreign missions in India.
Security has been beefed up along all Jewish worship places including synagogues, 'Chabad Houses' which is being frequented by Israeli tourists, they said.
LeT has details of various Chabad houses as the Pakistani-American citizen David Headley, at present undergoing 35 year prison term in Chicago, had carried out reconnaissance at these places.
