Ukraine's acting government has resumed its military operation against pro-Russian activists in the eastern part of the country after a short pause.
The interim government in Kiev re-launched on Wednesday its "anti-terrorist operation" in the eastern regions of Slavyansk, Kramatorsk, Donetsk and Lugansk.
The operation against pro-Russian protesters in the east was suspended during the Easter holidays and a Geneva agreement signed last week by Russia, Ukraine, the United States and the European Union.
The Geneva deal was reached on April 17 and meant to ease tensions between the Kiev government and protesters in the east.
However, tensions have remained high, with the Kiev government blaming Russia for escalating the situation.
Russia has rejected the accusations that it was behind the outbreak of violence in eastern Ukraine and that it has failed to meet its commitments based on the Geneva deal.
Pro-Russian demonstrators have so far refused to recognize the Geneva accord, with their leaders renewing calls for local referendums on independence.
