 Many were arrested during protests in 2020, when Alexander Lukashenko was declared president for the sixth time after an election that was widely disputed. Now five political prisoners have been released. We don't yet know their identities, except for Riho Castasio, who was found guilty of supposedly trying to overthrow the government. He now has cancer, and Mr Lukashenko had said he'd only release what he called extremists if they were seriously ill.
