Ukrainian pop star Ruslana has been one of the leading voices of protest in opposition to Russia's influence in her country over the past few months.
She has been a fixture in Kiev's Maidan Square - singing the national anthem night after night and using her influence to speak out for Ukraine's future.
Ruslana became a national sensation after winning the Eurovision Song Contest in 2004.
She sat down with the BBC's Katty Kay in Washington, DC, where she was accepting a humanitarian award.
