Ukraine crisis: Debaltseve 'in total shock'

The Ukrainian capital, Kiev, has been marking the first anniversary of the clashes between protesters and police which toppled ex-President Viktor Yanukovych.

More than 100 people died in the violence in Maidan Square in the centre of the capital one year ago.

The killings triggered the collapse of Ukraine's pro-Russian government, prompting Moscow to annex Crimea and sparking a separatist war in the east.

One of the towns engulfed by the ensuing violence is the strategically important town of Debaltseve, from where Paul Adams reports.
