Several European airlines have said that they will not fly over Belarus, days after a dissident journalist was arrested on a flight diverted to Minsk.
Air France is the latest major carrier to ban overflights. Neighbouring Ukraine and Poland are stopping all flights to and from Belarus.
Western countries accuse Belarus of hijacking the Ryanair plane carrying journalist Roman Protasevich on Sunday.
The Greece-Lithuania flight was rerouted over a supposed bomb threat.
Belarus authorities on Monday released video of Mr Protasevich that appears to have been recorded under duress.
He faces charges related to his reporting of last August’s disputed election and subsequent crackdown on mass opposition protests, and has said he fears the death penalty after being placed on a terrorism list.
Belarus is the only European country that still executes prisoners.
