Hundreds of Russians lined up outside an Istanbul club on Tuesday to get a glimpse of Oxxxymiron, a rapper who has rattled the Russian celebrity world with bold statements against his country's invasion of Ukraine.

The 37-year-old, whose real name is Miron Fyodorov, postponed concerts in Moscow and St. Petersburg because of the Russian invasion, which he has called a "catastrophe and a crime."

Russia calls its actions in Ukraine a "special operation” that it says is not designed to occupy territory.
