KYIV, July 23 (Reuters) - Ukraine has called on the United Nations and Turkey to ensure that Russia fulfills its commitments under the agreement for a safe corridor for grain exports from Ukraine's Black Sea ports, the foreign ministry said on Saturday.

Russian missiles hit infrastructure in Ukraine's port of Odesa on Saturday, a day after Russia and Ukraine, with mediation by the United Nations and Turkey, signed a deal to reopen Black Sea ports to resume such exports.
