Three lawyers who once represented the late Russian opposition leader Alexei Navalny were convicted by a court Friday as part of the Kremlin’s crackdown on dissent that has reached levels unseen since Soviet times.

Arrested in 2023, the lawyers were charged with extremism for relaying messages from Alexei Navalny while he was in prison before his death.

The trio were arrested as authorities intensified pressure on the jailed Kremlin critic, who died last February.
