Vladimir Kara-Murza, a prominent Russian human rights advocate and Kremlin critic, was sentenced to 25 years in prison by the Moscow City Court on Monday after publicly condemning Russia's war in Ukraine.

"Based on the results of the trial, for Vladimir Vladimirovich Kara-Murza, by partial addition of sentences, to be sentenced to a final sentence of imprisonment for a term of 25 years to be served in a strict regime correctional colony. The verdict of the Moscow City Court has not yet entered into force," a statement from the court read.

Kara-Murza will appeal the sentence, his lawyer, Vadim Prokhorov, told CNN on Monday.

Kara-Murza was initially detained one year ago, hours after an interview with CNN in which he criticized Russian President Vladimir Putin's "regime of murderers."
