TOPSHOTS Ukrainian policemen try to stop pro-Russian protesters from storming the regional government building in the eastern Ukrainian city of Kharkiv on April 13, 2014. Ukraine's acting president accused Russia of waging war in his country's eastern belt as fresh clashes left at least two dead and led the United Nations Security Council to announce emergency talks late on April 13. The heavily Russified region has been riven by unrest since pro-Western leaders rose to power in February on the back of bloody protests against the old regime's decision to reject an EU alliance and turn towards Moscow.
