'Nervous atmosphere' in Sloviansk
A tense standoff continues in eastern Ukraine, where pro-Russian separatists, many of them armed, are occupying official buildings in at least nine cities and towns.
Russia, Ukraine, the EU and US earlier agreed that illegal military groups in Ukraine must leave official buildings.
Olga Ivshina described the atmosphere in Sloviansk following the deal, struck in Geneva on Thursday, as "nervous".
