A miner looks on at the Gorniak 95 coal mine in the town of Makiyivka , near the regional capital of Donetsk in eastern Ukraine, May 15, 2014. Donetsk and Luhansk yield more than 15 percent of Ukraine's GDP, including around a third of its industrial output from the giant steel smelters and other heavy industry of the Donbass, one of Europe's most productive coal-producing regions.
