Ovsyannikova drew international attention in after appearing behind the anchor of an evening Russian news broadcast with a sign that said, "Stop the war, don't believe the propaganda, they are lying to you here."

French prosecutors are investigating a suspected poisoning Thursday of a Russian journalist who fled after denouncing the war in Ukraine on live TV.

Marina Ovsyannikova called emergency services and was hospitalized after suddenly falling ill as she left her Paris apartment and said she suspected she was poisoned, the Paris prosecutor’s office said.
