Pro-Russian rebels have shot down two of Ukraine’s army helicopters during an “anti-terror” operation in the eastern city of Sloviansk, Kiev says.
Ukraine’s military said a pilot and serviceman were killed and nine rebel checkpoints seized.
However, separatists at three Sloviansk checkpoints told the BBC they were still in control there.
Russia says Kiev’s actions “killed the last hope” for a deal agreed last month in Geneva aimed at defusing the crisis.
