TALLINN, Estonia (AP) — Authorities in Belarus on Thursday announced raids and the seizure of property belonging to 104 opposition activists who have fled the country, the latest step in a crackdown on dissent that has continued unabated for nearly four years.

Belarus’ authoritarian president, Alexander Lukashenko, unleashed the crackdown in August 2020, when mass protests erupted against his rule following his disputed reelection that the opposition and the West have denounced as rigged.

More than 35,000 people have been arrested, thousands have been brutally beaten in custody, and dozens of independent news organizations and rights groups have been shut down, and journalists imprisoned.

About 500,000 people have since fled the country of 9.5 million, and the authorities this year began a campaign against Belarusians abroad who call for tougher sanctions against the country.
