Ukraine's foreign minister called it "a day of relief for the world", especially for countries threatened by food shortages and hunger because of the disrupted shipments.

The sailing was made possible after Turkey and the United Nations brokered a grain-and-fertiliser export agreement between Russia and Ukraine last month.

Russia's conflict with Ukraine has led to a worldwide food and energy crisis and the United Nations has warned of the risk of multiple famines this year.

Russia and Ukraine account for nearly a third of global wheat exports. But Western sanctions on Russia and fighting along Ukraine's eastern seaboard have prevented grain ships safely leaving ports.
