Ukrainians harvest the much-needed wheat in the war-torn Donbas region amid fears of an advance of Russian forces in the region. Russia's defence ministry says that a "final document" designed to unblock grain exports from Ukrainian ports will be ready "soon", following negotiations with Kyiv in Turkey this week. Russian President Vladimir Putin's decision to send troops to Ukraine in February has disrupted the export of grain form Ukrainian ports, worsening a food crisis around the world. IMAGES
