UNIAN memo. After the annexation of Crimea by Russia in March 2014, Ukraine's east was seized by Russian-backed militants, and on April 15, 2014, the Ukrainian government had to launch its first formal military action against the militants who had seized government buildings in towns and cities across eastern Ukraine. Less than a month later, separatists in the eastern regions of Donetsk and Luhansk declare independence after unrecognized referendums.
