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.

Vadim Kobzev, Igor Sergunin and Alexei Liptser were already in custody and were given sentences from 3 1/2 to five years by a court in the town of Petushki, about 100 kilometers (60 miles) east of Moscow. They were arrested in October 2023 on charges of involvement with extremist groups, as Navalny's networks were deemed by authorities.
