Vigil by sky marshals on board flights have been intensified while security drills at the airport in Kolkata have been stepped up in view of the terrorist attacks in Mumbai.
The practice of deploying sky marshals as passengers on board flights has been continuing for a long time, but in view of the recent terrorist attack at Mumbai, vigil by them has been intensified, airport sources said on Sunday.
The National Security Guards also conducted rehearsals at the NSC Bose International Airport in this week in dealing with a terrorist strike.
CISF sources said a team of 126 NSG commandos flew in here on Thursday and joined 50 of their colleagues who are already posted here. Later, they practised drills at the airport and onboard an aircraft as well.
They taught security personnel in charge of the airport, methods to counter such situations.
CISF commandant Jayati Ghosh said, "The personnel have been reshuffled for better orientation and the security system at all 14 gates of the airport has been intensified."
