Russian missiles hit infrastructure in Ukraine's port of Odesa on Saturday, the Ukrainian military said. 

"The enemy attacked the Odessa sea port with Kalibr cruise missiles. Two of the missiles were shot down by air defences. Two hit port infrastructure," Sergiy Bratchuk, a representative of the Odesa region said in a statement on social media.

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.

There has been no response yet from the Russian side.
