Jailed Russian opposition leader Alexei Navalny was hit with new charges by Russia Friday, according to reports.

Navalny, 47, is already serving more than 30 years in prison after he was found guilty of charges that he and his supporters say were politically motivated.

This time, he said in social media posts shared by his spokesperson that he has been charged under article 214 of Russia’s penal code, which covers crimes of vandalism.

Navalny, a longtime critic of Russian President Vladimir Putin, said that the Kremlin wants to “initiate a new criminal case against me every three months.”

“I don’t even know whether to describe my latest news as sad, funny or absurd,” he said in comments posted on social media Friday via his team. “Never before has a convict in solitary confinement for more than a year had such a rich social and political life.”

A former lawyer, Navalny was arrested in 2021, after arriving in Moscow from Germany where he had recuperated from nerve agent poisoning that he blamed on the Kremlin.

He was since handed three prison terms and faced months in solitary confinement after being accused of various minor infractions, according to reports.
