There is no evidence that Belarusian KGB or any other secret service agents were on the Athens-to-Vilnius Ryanair flight that was diverted to Minsk in order to arrest a dissident on board, Greece's prime minister said Thursday. "We have no indication there were KGB agents or any security service agents on board the plane. None. Zero. And we investigated it very carefully," Kyriakos Mitsotakis said in an interview with Germany's Bild tabloid. The incident on Sunday, which led to the detention of opposition journalist Roman Protasevich and his companion Sofia Sapega, has triggered international condemnation. The European Union has since banned Belarusian planes from the bloc's airspace and urged EU airlines to avoid flying over the ex-Soviet country. Mitsotakis said the plane diversion, which Belarus claimed was due to a supposed bomb threat, was "an act of state-sponsored piracy" with the sole purpose of arresting Protasevich. Belarus opposition figures and Ryanair CEO Michael O'Leary have suggested that members of the Belarusian security agency, still known as the KGB, were on the flight and also deboarded in Minsk. But Belarusian President Alexander Lukashenko has dismissed the claim. mfp/kih/dl
