18 March 2014 Last updated at 12:38 GMT

Russian President Putin and two Crimean leaders have signed a treaty formalising the absorption of the Ukrainian Black Sea peninsula into Russia.

Earlier, Mr Putin told a special session of Russia's parliament that "in people's heart of hearts, Crimea has always been part of Russia".

Crimean officials say 97% of voters backed splitting from Ukraine in a controversial referendum on Sunday.

The EU and US have declared the vote illegal and imposed sanctions.
