A protester interrupted an evening broadcast on Russian state TV network Channel One on Monday holding a sign condemning Russia’s war against Ukraine.

As an anchor for the channel presented the 9 p.m. news, Marina Ovsyannikova, an employee at the network, burst on to the set shouting “Stop the war!” No to war!” while holding a sign saying: “Don't believe the propaganda. They're lying to you here.” It was signed in English: “Russians against the war.”

Security forces reportedly detained Ovsyannikova.

Speaking in a video posted on social media, Ovsyannikova said her father is Ukrainian and her mother is Russian.

The Russia-Ukraine war, which began on Feb. 24, has drawn international condemnation, led to financial sanctions on Moscow, and spurred an exodus of global firms from Russia.

At least 636 civilians have been killed and 1,125 injured in Ukraine since the beginning of the war, according to the UN. It has warned, however, that the true toll is likely much higher as it has not been able to gain access to areas of increased hostilities.

Some 2.8 million people have also fled to neighboring countries, said the UN refugee agency.
