Ukrainian border forces repelled Russian "armed saboteurs" at the frontier between Russian and Ukraine overnight, acting president Oleksander Turchinov has said.
Turchinov also said in a statement the operation to retake the eastern town of Slaviansk had not progressed as quickly as he had hoped, complicated by pro-Russian rebels hiding "behind the citizens" and "firing from apartment blocks".
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.
