Bangladesh on Monday evacuated hundreds of thousands of people to emergency shelters on the southwestern coast as a cyclone hit the country, as well as neighbouring India, officials said.
Government weather forecaster Sanaul Haq said Cyclone Aila made landfall between Bangladesh's Khulna district and Sagar Island in India's West Bengal state, unleashing a tidal surge as high as two metres (seven feet).
India has airlifted "elements'' of its para-brigade based in Agra to Kalaikunda in West Bengal to deal with any contingency which
arises due to the internal turmoil in Bangladesh.
Sources said over a battalion strength (over 1,000 soldiers) of the 50 Independent Parachute Brigade was moved on Sunday from Agra to Kalaikunda, which has a large IAF base.
"Depending on the situation, more could follow. With Bangladesh army progressively taking over from the paramilitary BDR in posts along the Indo-Bangladesh border, it's a precautionary move,'' said a source.
