Ukraine's president says Black Sea grain export deal must be extended

Ukrainian President Volodymyr Zelenskiy told the U.S. Ambassador to the United Nations on Tuesday that the U.N.-brokered Black Sea grain export deal that unblocked three major Ukrainian ports must be extended.

"It is necessary for the grain agreement to continue in the future. Ukraine is ready to remain the guarantor of world food security," he wrote on the Telegram messaging app following talks in Kyiv with the ambassador, Linda Thomas-Greenfield.
