Two Russian journalists who also work for Western media outlets have been remanded in custody in Russia on extremism charges related to their alleged connection with a group founded by the late leading Russian opposition figure Alexei Navalny.
One of the journalists is a cameraman who also worked for the US-based Associated Press news agency. According to the AP, he was arrested in the northern Russian region of Murmansk.
The news agency said it was "very concerned" about the arrest.
Another journalist who had also worked for several foreign news organizations was also detained in Moscow, as reported by numerous Russian media outlets.
Both journalists are accused by Russian authorities of participating in an extremist organization.
They allegedly supplied material for a publication linked to Navalny, an outspoken critic of Russian President Vladimir Putin who died in February while being held in a Russian penal colony.
Russian sources said they allegedly supplied videos for the YouTube channel "Navalny Live," which is banned in Russia.
A Russian court ordered the two journalists held in pre-trial detention on Saturday, an order that will initially apply until June.
Since Navalny's death and the re-election of Putin in March, the Russian state has once again stepped up its repression of opposition groups and independent media.
At the same time, the pressure on foreign media reporting from Russia is growing.
Last Friday, an employee of the Russian edition of the business magazine Forbes was arrested for allegedly discrediting the army.
A journalist who shot the last videos about Navalny before his death is also in custody.
Navalny's anti-corruption foundation is currently causing a stir in Russia with a newly released documentary, which covers rampant corruption in the country in the 1990s under president Boris Yeltsin and Putin's path to power.
