The crews of two helicopters shot down in south east Ukraine have been evacuated, the country's defence ministry has said.
It also called for the release of a "heavily-wounded pilot" who was pictured being taken by pro-Russian separatists broadcast on Russian state media.
In a statement, the ministry said: "One heavy-wounded pilot was captured by extremists who waited for the emergency landing of the helicopter. His location is known. [The government has] taken measures for his urgent liberation."
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.
