With recent terror attack on a Brussels' airport leading to fresh concerns over airport security in the country, a security agencies report says India has not given specialised CISF security cover to 27 such sensitive facilities for the last five years due to lack of funds.
Such functional airports are being taken care off by other security forces like CRPF, India Reserve Battalions (IRBs) or state police units, keeping CISF out of picture.
A report early this year had also expressed its apprehension, and said it found it "quite scary to know that the security of eight of our hyper-sensitive and 19 of our sensitive airports are not covered by the CISF which has now become the only specialised force for aviation security."
CISF has a trained unit for the task called the Aviation Security Group (ASG) and has almost 22,000 men and women commandos.
Force was first given task of airport security in the year 2000, beginning with the Jaipur airport after the hijack of Indian Airlines flight IC-814 and its last ASG was inducted in 2011 at Diu airport.
A recently published by the CISF and intelligence agencies has borrowed from the opinions of the Parliamentary committee to emphasise the need for stepping up security at the airports.
"In the recent report...the Committee has opined civil aviation security is an integral and important element of national security. Airports are critical infrastructure and very vital from the perspective of national security.
"Any large-scale damage or terrorist attack on the airport would be catastrophic with far reaching grave implications for the citizens and the economy. Explanations given to the committee for non-deployment of CISF at remaining airports was lack of funds," the report, said.
