In the Ukraine the new western-backed interim administration blames violence in the east of the Ukraine on pro Russian antagonists.
Pro Russian protesters in the Ukraine, Crimea and Russia support the Crimean secession plan. Russia claims it will respect the outcome of the vote which the west calls illegal. Western leaders will not recognise the outcome of Sunday's vote.
Tensions continue to rise in the Ukraine and Russia. What will happen after the vote is not known. Once the result is announced to the world action must surely follow. Will that action be sanctions or miltary action?
Opinion: Difficult times for Ukrainian citizens living in their homeland. Difficult times for the world. There is foreign interference from many sources and Russia appears to have its sights set on recapturing the Crimea. The history behind ownership of the Crimea is complex. With the Russian Fleet having its naval base in the Crimea Russia was bound to act when Russian backed leaders in Kiev, the Ukrainian capital, were ousted.
