More than 60 airports operational in tier-two and tier-three cities under the Centre’s regional connectivity scheme UDAN will soon be brought under a comprehensive anti-terror security cover of armed CISF personnel with the deployment of around 1,650 troops, officials said. The proposal is awaiting final policy sanction from the home ministry. The bureau of civil aviation security (BCAS), in consultation with the ministry of civil aviation and the CISF, finalised the proposal for the “very important security measure” required for the safety of passengers taking flights from small air terminals across India.
