New Delhi: Dense fog enveloped several parts of the national capital, leading to disruption in flight operations at the Indira Gandhi International Airport in New Delhi. Arrivals and departures have largely been put on hold at the IGI airport. Two flights were also diverted between 5.30 am and 8.30 am.

"Flight operations have largely been put on hold. Very few aircraft are departing and that too on the basis of their size, visibility and ATC (air traffic control) clearance for taking off," an airport official said.
