Pro-Russian separatists in Sloviansk are braced for further clashes with Ukrainian government troops, after a tough firefight on Monday.
The Ukrainian government claims that more than 30 pro-Russian fighters were killed as the two sides fought for control of the rebel stronghold.
Meanwhile, at a Council of Europe meeting, Russia's foreign minister Sergei Lavrov ruled out the idea of a new round of talks to diffuse the crisis.
