A Russian journalist who interrupted a live TV news broadcast has made an appearance in court. She was fined for violating protest laws.

On Monday, Marina Ovsyannikova ran behind a news anchor shouting "Stop the war!" She held up a sign that read, "Don't believe propaganda. They are lying to you here."

She was detained for about 14 hours. On Tuesday, she appeared in court, was found guilty, and received a fine of about 280 dollars.

Ovsyannikova said she acted alone. She said she opposes the invasion and described it as "really terrible."

Ovsyannikova's father is Ukrainian and her mother is Russian. She works as an editor for state-run TV and said she regrets spreading Kremlin propaganda.

More Russians are speaking out. A human rights group says about 15,000 protesters have been detained since the start of the invasion.
