Air India and IndiGo cancelled scheduled flights to and from Dhaka with immediate effect on Monday due to the emerging situation in the wake of Bangladesh Prime Minister Sheikh Hasina resigning amid unprecedented anti-government protests.

A Vistara official said the airline has cancelled its flights to Dhaka for Tuesday. The airline operated the flight from Mumbai on Monday.

While Air India operates two daily flights from Delhi to Dhaka, Vistara flies daily flights from Mumbai and three weekly services from Delhi to the Bangladesh capital.

IndiGo has flights to Dhaka from the national capital, Mumbai, Chennai and Kolkata. The number of flights that are operated by the airline could not be immediately ascertained.

"In view of the emerging situation in Bangladesh, we have cancelled the scheduled operation of our flights to and from Dhaka with immediate effect. We are continuously monitoring the situation and are extending support to our passengers with confirmed bookings for travel to and from Dhaka with a one-time waiver on rescheduling and cancellation charges," an Air India spokesperson said in a statement on Monday.

IndiGo said that in view of the ongoing situation in Dhaka, all flights scheduled for tomorrow have unfortunately been cancelled.

"We understand that this may cause significant inconvenience and disruption to your travel plans and we sincerely regret this development," it said in a post on X.

In Dhaka, Bangladesh Army Chief General Waqar-uz-Zaman said Hasina has resigned and an interim government is taking over the responsibilities.
