New Delhi [India], December 17 (ANI): Ten flights were cancelled at Indira Gandhi International (IGI) Airport, New Delhi, on Wednesday morning due to low visibility conditions, airport authorities said.

Meanwhile, flight operations at Chennai International Airport were also disrupted on Wednesday morning after dense fog and adverse weather conditions in Delhi and other northern states led to the cancellation of 11 flights, airport authorities said.

According to an official statement, four departing flights and seven arriving flights were cancelled during the day. The cancellations were attributed to persistent dense fog, poor weather, and air pollution affecting flight operations across Delhi and several northern regions over the past few days.

'Flight services in Delhi and other northern states have been severely impacted due to dense fog and adverse weather conditions. Several flights bound for Delhi were unable to land and were diverted to other airports,' the statement said.

As a result, flight services between Chennai and northern cities have remained disrupted. On Wednesday, four outbound flights from Chennai to Delhi, Jaipur, Kolkata, and Ghaziabad were cancelled.

Similarly, seven flights scheduled to arrive in Chennai today from Delhi, Jaipur, Patna, Pune, Kolkata, Indore, and other cities have also been announced as cancelled.

The cancellation of 11 flights in a single day caused significant inconvenience to passengers.
