Ukraine crisis: 'Still thousands in Kiev square'

As Ukrainian President Viktor Yanukovych is reported to have left the capital, Kiev, there are concerns about a possible power vacuum in the country.

A deal brokered on Friday promising a coalition government within days has already seen opposition figures appointed as parliamentary speaker and interior minister.

But many opposition protesters say they want elections before the end of May, not the end of December as agreed.

The BBC's Tim Willcox reports from Independence Square, where he met some of those protesting.
