The World Food Programme is appealing to Russia to reopen Ukraine’s ports on the Black Sea to allow for shipments of grain. Speaking to a U.N. donors’ conference in Warsaw, Poland, on Thursday, WFP director and Nobel Peace Laureate David Beasley said Russia’s invasion of Ukraine has pushed global food prices to near record highs, raising the cost of commodities like wheat, corn and cooking oil.

David Beasley: “If we don’t get those ports open in the Odessa region, we’re going to have economic agricultural collapse inside Ukraine, a country that feeds 400 million people. And I can tell you the devastation globally will be beyond anything we have seen.”
