Major airports across India have been put on alert following a threat that warns of an attack.
Reports says that an anonymous threat letter was received which warned that two flights one each originating from Mumbai and Ahmedabad airports could be targeted.
However, authorities believe the letter is a hoax and are not taking any chances and security has been stepped up.
Based on the reports and warning a bomb disposal squad and an anti-hacking unit were this morning deployed at Cochin International airport. Similar emergency mechanisms have also been activated at other airports too.
The threat letter was received by the director of the Airports Authority of India. It warned that the Friday night flight from Ahmedabad to Mumbai and early Saturday morning flight from Mumbai to Cochin will be targeted, said reports.
According to the reports based on intelligence inputs, suicide bombers could board two Air India flights from Mumbai and Ahmedabad airports on Saturday morning.
Also, a letter to airports in connection with the threat was issued by the Bureau of Civil Aviation Security (BCAS).
The letter reads: "An input received says: Air India flight on the midnight of October 24 (early morning of October 25) from Ahmedabad to Mumbai and early morning flight from Mumbai to Cochin on 25th morning at 0500 hrs. Suicide bomber in each flight separately. Please check thoroughly. Secondary security checks may be carried out at Ahmedabad and Mumbai airports for all flights around the concerned dates."
