Russia's communication watchdog has blocked the website of the OVD-Info protest-monitoring group, which has for years documented anti-Kremlin protests, following a court ruling, Interfax news agency reported on Saturday.
The news agency said the ruling on restricting access to the ovdinfo.org site was issued by a court in the Moscow region on December 20. The website currently shows a message saying access to it is restricted on the basis of a federal law on information, information technologies and data protection.
Russia declared the OVD-Info group a "foreign agent" in September, in a move that critics say is designed to stifle dissent.
Moscow has recently labeled several outlets "foreign agents," a legal designation used for what authorities say are foreign-funded organizations engaged in political activity.
OVD-Info did not immediately respond to a request for comment.
