AIRPORTS ACROSS the country were put on high alert on Thursday after a letter warning of Al-Qaeda attacks was found at the Tiruchirapalli airport in Tamil Nadu. The anonymous letter said militants would blow up airports in Tamil Nadu and Kerala.
Civil Aviation Secretary Ajay Prasad said security was strengthened at all airports. Emergency anti-sabotage and anti-hijacking measures have been put in place.
Apart from X-Ray scans, security personnel will examine the hand baggage of all passengers. There could be a second baggage check at the boarding gate.
There will be restrictions on carrying liquids and gels on board.
Visitors to the airport will be checked and vehicles will not be allowed to park on the premises for more than "the required time". Air travellers have been asked to report early. Prasad said the threat letter was written in Tamil and addressed to the airport director. It said militants would strike at the Chennai airport with "sophisticated technology".
