India's aviation regulatory body, Directorate General of Civil Aviation (DGCA) imposed a fine of Rs 20 lakh on Kolkata's Netaji Subhas Chandra Bose International Airport (NSCBIA) for violating safety norms by neglecting runway maintenance.

"After the regulator started safety auditing for airports a few months back, the audit report found that NSCBIA has committed serious safety norms violations, especially on the runway maintenance work. It has been decided to impose a fine of Rs 20 lakh," a senior official from DGCA confirmed to ANI.
