Planes from Belarus have been blocked from flying in EU airspace in response to the arrest of a journalist who is critical of the country's regime.
A Ryanair flight was diverted to Minsk on Sunday to bring Roman Protasevich into custody.
US president Joe Biden's called it "outrageous".
The journalist has since appeared in a video confessing to crimes - but his father Dzmitry is certain he was forced to do it.
"My son cannot admit to creating the mass disorders because he didn't do any such thing.
"It's unlikely he went for a deal with the prosecutors, it's just that I think he was forced to record the message.
"We especially can't understand when the message was recorded, and how truthful it is."
