The decision by the Russian prosecutor general’s office is the latest move in a crackdown on Kremlin critics, journalists and activists, which has intensified since Moscow’s invasion of Ukraine in February 2022.
In a separate statement on Friday, the office said it was opening a case against Russian feminist punk band Pussy Riot that would designate the group as an “extremist” organisation.
Separately, Russia’s Supreme Court designated on Thursday the Anti-Corruption Foundation set up by the late opposition activist Alexey Navalny as a “terrorist” group.
