A Russian court has said that it detained a journalist, accusing him of helping create a YouTube channel operated by a team that supports the late opposition leader Alexey Navalny.
Navalny died in a penal colony in February.
The court in Moscow said in a post on a social media on Saturday that Konstantin Gabov helped prepare materials such as photographs and videos for the YouTube channel.
Navalny's team is designated an extremist group in Russia and banned from any activities. They mainly work outside of the country.
The Russian court does not reveal Gabov's nationality but it says that he works for Reuters news agency.
Russian and western media say that he has worked for Russian and German media as well as Reuters.
Also on Saturday, a court in Russia's far eastern city of Khabarovsk, ordered a reporter of a Russian edition of the US business magazine Forbes to be placed under house detention.
The reporter is accused of spreading false information.
President Vladimir Putin is intent on suppressing any criticism. He will begin serving his fifth term on May 7.
