As many as 20 flights from Delhi’s Indira Gandhi International Airport (IGIA) were delayed on Saturday due to inclement weather and other operational issues, said an official at the Delhi airport.

Cold wave conditions and dense fog is being witnessed all over North India, including the national capital, which disrupted flight operations at the airport with around 13 inbound flights delayed from different destinations.

"There was no flight diversion reported till 6 AM," said an official at the airport.
