Ukraine orders full military mobilisation over Russia moves

Ukraine has ordered a full military mobilisation in response to Russia's build-up of its forces in Crimea.
Prime Minister Arseniy Yatsenyuk said Ukraine was "on the brink of disaster".
In Crimea, Ukrainian soldiers faced off with Russian soldiers surrounding their bases while the Russian army is said to be digging trenches on the border with mainland Ukraine.
US Secretary of State John Kerry has warned Russia could be ejected from the Group of Eight developed nations.

Russian President Vladimir Putin, he said, was "not going to have a Sochi G8, he may not even remain in the G8 if this continues," referring to a planned summit in Russia in June.

"He may find himself with asset freezes, on Russian business. American business may pull back, there may be a further tumble of the rouble.

"You just don't in the 21st Century behave in 19th Century fashion by invading another country on completely trumped-up pretext," Mr Kerry told the CBS program Face the Nation.
