India airports across the country were on high alert after a terror e-mail and the coast of west state Gujarat was also on tight security Thursday morning, reported local news channel Times Now.

India Bureau of Civil Aviation Thursday morning issued a hijack warning for Delhi, Bangalore and Chennai airports.

Previously the Bureau of Civil Aviation have received an e-mail, which said that on December 6, terror groups might strike at these airports to hijack a plane.

All hand baggage, due to this warning, will be physically checked by security forces even after they have been put through the X-ray.

All cars approaching the airports will also be checked and the passengers need to report three hours in advance.

The police are trying to find out who is behind the e-mail, which was first sent to a news organization in Gujarat last week.

The coastal districts of Gujarat is also on high alert now, after the state home ministry received specific information of threats to certain places on the Gujarat coast, sources said.

Sources in the Jujarat state home ministry said that about a dozen sleeper cells are likely to be activated.

Many cities along Gujarat coast have been put on high alert.
