Ukraine crisis: UN declares Crimea vote illegal

The UN General Assembly has approved a resolution describing the Moscow-backed referendum that led to Russia's annexation of Crimea as illegal.

It comes after the International Monetary Fund (IMF) agreed to a loan deal with Ukraine worth $14-18bn. The US Congress also passed legislation on Thursday backing a $1bn loan guarantee for Ukraine.

Tensions are high between Russia and the West after pro-Russian troops annexed Ukraine's southern peninsula.
