Russian authorities on Wednesday detained a former state TV journalist who quit after making an on-air protest against Moscow’s war in Ukraine, and charged her with spreading false information about Russia’s armed forces, her lawyer said on social media.

Marina Ovsyannikova was charged over a protest she staged last month, invoking Russian President Vladimir Putin’s name in a banner that said: “Putin is a killer, his soldiers are fascists. 352 children have been killed [in Ukraine]. How many more children should die for you to stop?”

If tried and convicted, Ovsyannikova faces up to 10 years in prison under a new law
