Two leading opposition figures who challenged Belarus’s discredited presidential polls have been jailed for trying to threaten national security and seize power.
Protest organiser Maria Kolesnikova was jailed for 11 years while lawyer Maxim Znak received 10 years.
Prosecutors accused the council of trying to stage a coup.
On Monday, a court in Minsk, the capital, found Kolesnikova and Znak guilty of crimes including plotting to seize power, threatening national security and extremism.
They both denied the charges against them and denounced the trial as a sham. Their lawyers said they would appeal against the verdict.
Tens of thousands of protesters were detained and many were brutally beaten, as Mr Lukashenko, who has been in power since 1994, tried to silence dissent.
Independent journalists and activists have been arrested in a crackdown that continues a year later, with some 650 political prisoners in detention, activists say.
The head of Belarus’s opposition, Svetlana Tikhanovskaya, was forced into exile in Lithuania the day after she claimed victory in the presidential election.
In contrast, her opposition colleague, Kolesnikova, resisted attempts to have her thrown out of Belarus, tearing up her passport, after she was seen being bundled into a vehicle in Minsk.
Weeks later, she was charged with incitement to undermine national security.
Kolesnikova has already been behind bars for over 11 months. As she appeared in court for sentencing on Monday, she smiled at state TV cameras, and made heart shapes with her hands.
A flute player in the country’s philharmonic orchestra, she has become a symbol of the protest movement in Belarus.
