Nepal's King Gyanendra Friday restored democracy in his country.
However, India Friday reviewed the developments in Nepal arising out of mass protests against the monarchy and asked the security forces to be alert to prevent anti-India elements from infiltrating into the country.
"The situation along the Indo-Nepal border was reviewed at a meeting of top officials. The Seema Suraksha Bal was asked to facilitate movement of trucks stranded at the border points to ensure that essential commodities and medicines reach the Nepalese people," Union Home Secretary V K Duggal said.
"The people of Nepal should not suffer," he said after chairing a high-level meeting, which was attended among others by senior officials from Home Minsitry, SSB, Army and intelligence agencies.
Duggal said the security forces have been asked to take all necessary measures in case the situation turns bad.
Those present at the meeting were Special Secretary (Internal Security) in the Home Ministry G S Rajagopal, Joint Secretary (Internal Security) L C Goyal and Director General of SSB Tilak Kak.
Official sources said the SSB was asked to keep a tight vigil as "certain Maoists" and anti-India elements could try and sneak into the country.
As many as 18,000 SSB personnel are posted along the Indo-Nepal border and more would also be deployed soon.
"We are concerned over the situation and we are keeping a close watch," a senior official present at the meeting said.
About the influx of people from the Himalayan kingdom, the sources said that a few hundred people have arrived but the situation was under control.
"The situation is under control at the border and not volatile and no large-scale influx has taken place so far. The SSB personnel are prepared to meet any eventualities," the official said.
