Ukraine crisis: 'Protesters should stay in square'

Opposition leader Vitaly Klitschko has said it is right that protesters keep up their presence in the streets, saying Saturday's events were "just a step".

Speaking to the BBC's Steve Rosenberg, he said he thought they should not clear until "we start to reform," saying the country still had to "make many steps."

He said his goal was to make Ukraine a "modern European country, with European standards of life... if I can do that through the president position I'll give my best."
