Two Femen protesters were arrested in Crimea's capital Simferopol on Thursday after staging a topless demonstration against Russia's intervention in Ukraine in front of Crimean Parliament, AFP reports.

One protestor was stopped by police within seconds while another ran around, repeatedly shouting "Stop Putin's War", which she had also written across her chest.

She was eventually detained and taken away in a van by security forces, while some people who had been watching the protest shouted: "Prostitutes!"

To recall, with pro-Russian forces in control of Crimea, the peninsula's parliament on Thursday set a referendum for March 16 on whether it should become part of Russia.
