ISTANBUL (AP) — Russian and Ukrainian officials have signed deals to end a standoff over grain exports brought on by the war in Ukraine. Ukraine is one of the world’s key breadbaskets but a Russian blockade of its ports has threatened food security around the world. The two countries signed separate agreements Friday with Turkey and the United Nations so that Ukraine could export 22 million tons of grain and other agricultural products stuck in Black Sea ports by the war. The secretary-general of the U.N. and Turkey’s president joined the signing ceremony in Istanbul. The U.N. chief called the deal “a beacon of hope” on the Black Sea that will help hungry people around the world.
