Russia agreed last Wednesday to rejoin a wartime agreement allowing Ukrainian grain and other commodities to be exported.
President Putin said Moscow had received assurances that Ukraine would not use the humanitarian export corridors to attack Russian forces. He warned Russia reserves the right to withdraw again if Kyiv breaks the agreement.
Turkey said export shipments would resume Wednesday, prioritizing exports to African nations, including Somalia, Djibouti, and Sudan.
U.N. humanitarian chief Martin Griffiths said that 23 percent of the cargo exported from Ukraine under the grain deal went to lower- or lower-middle-income countries, which also received 49 percent of all wheat exports.
