NEW DELHI, Dec. 5 (Xinhua) -- The New Delhi international airport returned to normal after being shut down for about 20 minutes early Friday following reports of gunfire near the arrival terminal, reported Indo Asian News Service.
The flight operations have resumed now as scheduled, while cars and passengers approaching the airport are still under tight security check.
The Central Industrial Security Force (CISF) of India denied any terror incident in the early morning, but the Delhi Police said investigations were still on.
Alarms were heard after a white car breached a security barrier and tried to approach the arrival terminal from a restricted road around 1.10 a.m.
A witness told reporters that he heard at least two gunshots from the direction of the unidentified car bearing a local registration number.
The gates of the airport were immediately shut down and an intensive search was launched. Three international flights were delayed because of the incident.
