Ukraine crisis: Russia demands guarantees from Nato

Vladimir Putin's chief spokesperson has said the West's response over the Ukraine crisis makes them "feel fear" and so they have taken "methods of precaution".

Dmitry Peskov said that Russia would like to receive a guarantee that Ukraine will not join Nato, as they are fearful of the Nato-affiliated countries on their borders.

President Putin accused the US of trying to subdue Russia, but gave assurances this would never happen.
