At least six people were injured after a portion of the roof of the Delhi airport's Terminal-1 collapsed on cars amid heavy rain today morning.

Many vehicles, including cabs, were damaged in the incident that was reported to the Delhi Fire Services (DFS) around 5.30 am, officials said.

The officials said the roof sheet and the support beams collapsed, damaging the cars parked in the pick-up and drop area of the terminal at the Indira Gandhi International Airport, one of the busiest airports in India.

Among the six injured, a man was rescued from a car on which an iron beam had fallen.

The injured have been shifted to hospital and a search operation is underway to make sure no one else is trapped in the damaged vehicles, officials said.

Union Minister of Civil Aviation Ram Mohan Naidu Kinjarapu said he was "personally monitoring" the roof collapse incident at the Delhi Airport.

"First responders are working at site. Also advised the airlines to assist all affected passengers at T1. The injured have been evacuated to hospital. Rescue operations are still ongoing," the newly-elected minister posted on X.

Parts of Delhi today received heavy rain for the second consecutive day. Rain, which brought respite from the scorching heat, also caused waterlogging in several parts of the national capital.

Visuals shared by the news agency ANI on X showed roads inundated and long traffic in parts of Delhi.

A car was also seen submerged at Minto Road.

On Thursday, rain in Delhi brought the temperature down to 35.4 degrees Celsius. The city recorded 5.2 mm of rainfall from 8:30 am till 5:30 pm.
