Belarusian authorities Wednesday declared the country's oldest and most prominent human rights group an extremist organization. The move against Viasna, founded by imprisoned Nobel Peace Prize laureate Ales Bialiatski, comes amid a yearslong crackdown on dissent in Belarus and exposes anyone involved in its activities to criminal prosecution. Belarus was swept by massive protests, some of which drew more than 100,000 people, after the August 2020 presidential vote handed a sixth term to the country's authoritarian President Alexander Lukashenko.
