Ukraine crisis: 'Illegal' Crimean referendum condemned
6 March 2014 Last updated at 22:39 GMT
The EU and US have joined Ukraine's government in condemning as "illegal" a move by the Crimea region to set up a referendum to join Russia.
The EU, meeting in Brussels, threatened "serious consequences" if Russia did not act to de-escalate the crisis.
Crimean MPs earlier set a date of 16 March for a vote on the referendum.
Russian troops took de facto control of Crimea, whose population is mostly ethnic Russian, in the wake of the fall of Ukraine's pro-Moscow president.
