Ukraine's prime minister has postponed Friday's scheduled visit to Russia, one day after Russia's top prosecutor said Moscow is still pursuing a bribery case against her.

Russia's Interfax news agency quoted a top Ukrainian official, Deputy Prime Minister Mykola Tomenko as saying Yulia Tymoshenko postponed her trip because of urgent social and economic problems in Ukraine. The agency quoted him as saying the change is not directly connected with the Russian comments.
