An unexploded shell lies in a field in Cherkaska Lozova, outskirts of Kharkiv, eastern Ukraine, Saturday, May 28, 2022. Ukraine is one of the world's largest exporters of wheat, corn and sunflower oil, but the war and a Russian blockade of its ports have halted much of that flow, endangering world food supplies. Many of those ports are now also heavily mined. (AP Photo/Bernat Armangue)
