Russia's tightly controlled TV news got a shock on Monday when an anti-war protester rushed onto the set of a live, primetime broadcast.

A woman ran behind the anchor shouting "Stop the war!" Her sign read "Don't believe propaganda. They are lying to you here."

The woman is now reportedly in police custody. Russian media have identified her as Marina Ovsyannikova.

Before the broadcast, she recorded an explanation which was uploaded to social media.

Her father is Ukrainian and her mother is Russian.

She works as an editor for state-run TV and says she regrets spreading Kremlin propaganda.

She says, "ow the whole world has turned away from us and the next 10 generations of our descendants will not wash away the shame of this fratricidal war. We the Russians are wise and proud, and it is up to us to stop this madness."

The Ukrainian President personally thanked Ovsyannikova for speaking out.

Volodymyr Zelenskyy said, "I am grateful to those Russians who do not stop trying to convey the truth, to those who fight disinformation and tell the truth, real facts, to their friends and loved ones."

He said Russians need to fight to ensure their country isn't cut off from the rest of the world.
