Ukraine's acting President Oleksandr Turchynov has demanded that Russia pull back troops from the border with Ukraine, stop interfering with the country's internal affairs and end its "black mail.'
Mr Turchinov broadcast a brief address to the nation after Russia said it had begun military exercises near the border in response to escalation by Ukraine.
European Union foreign ministers added 13 people to their visa ban and asset freeze list over Ukraine's crisis.
Well that’s the voting over, and no surprises so far. A ‘Yes’ vote claimed to be 89% in Donetsk, and suddenly Ukraine is no more.
Nearly 90 percent of voters in eastern Ukrainian region voted for self-rule, the head of the separatist election commission said.
