All flights at Tribhuvan International Airport have been cancelled today due to unprecedented and serious circumstances and security concerns. The airport authority apologised for the inconvenience.

International flights have been halted since 12:45 pm following a billow of smoke near Koteshwar, said Hansa Raj Pandey, general manager at TIA. “The airport is not closed. We won’t close it either,” he added.

Crew members have been unable to reach the airport due to problems in movements, preventing flights from taking off. Domestic airlines, including Buddha Air, have suspended all flights citing security reasons.
