The incident at the domestic departure terminal of New Delhi‘s Indira Gandhi International Airport happened at around 5am local time on Friday as heavy pre-monsoon rains lashed the capital.
All flight departures from Terminal 1 were temporarily suspended as rescuers cleared the debris to save anyone trapped, the airport authority said.
Some support beams also collapsed, damaging cars in the pickup and drop-off area of the terminal, local media reported.
Of the six injured, one was rescued from a car on which an iron beam had fallen.
Civil aviation minister K Rammohan Naidu said first responders were working at the site and advised airlines to assist all affected passengers.
“Rescue operations are still ongoing,” he said in a post on X.
