Belarusian President Alexander Lukashenko ordered a Ryanair flight carrying a key opposition blogger and headed for Lithuania to land in the Belarusian capital Minsk on Sunday and detained him on arrival, officials and rights activists said.
Law enforcers detained activist Roman Protasevich, put on a wanted list after last year's mass street protests following an election in which Lukashenko had claimed a landslide victory.
The aircraft, flying over Belarus from Athens to Vilnius, had almost reached Lithuania when it changed direction and was escorted to Minsk amid reports that it had explosives on board, according to an online flight tracker and BelTA.
No explosives were found, BelTA said.
The Belarus department for organised crime control also reported that Protasevich had been detained but then deleted the statement from its Telegram channel.
Ryanair and the Lithuanian ministry of foreign affairs had no immediate comment.
Lukashenko personally ordered the warplane to escort the Ryanair Boeing to Minsk, state news agency BelTA reported.
In power since 1994, Lukashenko launched a violent crackdown on the 2020 street protests. Around 35,000 people have been detained since August, human rights groups say. Dozens have received jail terms. Authorities say that more than 1,000 criminal cases have been opened.
A Lithuanian airport authority spokeswoman told Reuters the plane, scheduled to land in Vilnius at 1100 GMT, was diverted to Minsk due to a conflict between the crew and a passenger.
The plane was expected to land in Vilnius from Minsk at 1500 GMT, she said.
Protasevich is one of the founders of the opposition news service NEXTA, a Telegram channel that has become one of the main sources of news about demonstrations in Belarus. It is hostile to Lukashenko and helps to coordinate protests.
Belarusian opposition politician Svetlana Tikhanouskaya, Lukashenko's main rival at the last election, said Belarus authorities "placed at risk safety of passengers on board and all of the civil aviation for the sake of punishment of the man who was an editor of Belarus's largest independent Telegram channel".
