The Kremlin are "extremely worried" that it has not heard from its envoy sent to eastern Ukraine to help free foreign hostages, the spokesman for Russia's President Vladimir Putin said.
In a statement, the Kremlin said: "Special Presidential Envoy Vladimir Lukin was sent to Ukraine to take part in talks on freeing the foreign military observers taken hostage earlier.
"Russian officials have not been able to make contact with Mr Lukin since the Ukrainian military operation began".
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.
