The Russian news site Mediazona is shut down, writes AFP.
The site was considered one of the last independent media left in Russia.
"This is because we report honestly on what is happening in Ukraine and call the invasion an invasion, and the war a war," they wrote in a statement.
Mediazona was started by two members of the artist collective Pussy Riot, Nadya Tolokonnikova and Maria Alyokhina, after they were released from prison in 2013 - two years after they were convicted of hooliganism.
The site has, among other things, reported on the Russian judiciary and the conditions in the country's prisons.
15 years in prison for violating censorship
Several Russian media have been blocked by the country's censorship authority Roskamnadzor in the past week.
The TV channel Dozhd shut down last week after an emotional last broadcast.
And the newspaper Novaya Gazeta, whose founder Dmitry Muratov received the Nobel Peace Prize last year for his publicist work, stops reporting on the war.
This comes after the Russian lower house on Friday passed a law that could give 15 years in prison for journalists who report "fake" news about the Russian military and the war in Ukraine.
