Ryanair Flight 4978

Ryanair Flight 4978 was a regularly scheduled international passenger flight from Athens International Airport, Greece, to Vilnius Airport, Lithuania, operated by Buzz, a Polish subsidiary of the Irish airline Ryanair. On 23 May 2021, while in Belarusian airspace, it was diverted by the Belarusian government to Minsk National Airport due to alleged claims of a Hamas bombing attempt, where two of its passengers, opposition activist and journalist Roman Protasevich and his then girlfriend Sofia Sapega, were arrested by authorities. The aircraft was allowed to depart after seven hours, reaching Vilnius eight and a half hours behind schedule.

The act was condemned by the European Union (EU), NATO, Canada, the United Kingdom, and the United States, among others, and by some civil aviation authorities, while Russian officials backed Belarus. The EU and the European Union Aviation Safety Agency issued directives halting European airlines from flying over Belarusian airspace. The incident led to the eventual closing of the Embassy of Belarus in Canada.
