India received a terror e-mail targeting airports Thursday morning, reported local news channel Times Now.
Airports across the country are now on the high alert. The coast of west state Gujarat is also under tight security.
The Indian Bureau of Civil Aviation has issued a hijack warning Thursday morning for Delhi, Bangalore and Chennai airports.
Previously the Bureau of Civil Aviation received an e-mail, which said that on Dec. 6, terror groups might strike at these airports to hijack a plane.
Due to this warning all hand baggage 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.
