Ukraine crisis: Crimean MPs ask to join Russia
6 March 2014 Last updated at 23:14 GMT
MPs in Crimea have asked Moscow to allow the southern Ukrainian region to become part of the Russian Federation.
The parliament said if its request was granted, Crimean citizens could give their view in a referendum on 16 March.
Ukraine's interim Prime Minister Arseniy Yatsenyuk said the move had no legal grounds.
Crimea, a region whose population is mostly ethnic Russian, has been at the centre of tensions following the fall of Ukraine's pro-Moscow president.
