Ukraine crisis: Independence Square lights up to honour Kiev dead

Protesters in Kiev's Independence Square have paid tribute to those who have died in the city's violent clashes, on the day leaders from both sides signed an agreement aimed at ending the crisis.

Thousands of anti-government protesters still gathered in the square - the heart of the protests - heard prayers and sang hymns, while shining lights from their mobile phones to honour those killed.

But as Tim Willcox reports, one protester stormed the stage to demand President Yanukovych resign his post by Saturday morning.
