Pop star Ruslana: Putin's plan is to destroy Ukraine

2 May 2014 Last updated at 00:18 BST

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.
