Ukraine's Black Sea port of Odesa has resumed operations that had been suspended after a Russian attack on the region's energy system, Reuters reported, citing a spokesperson for the infrastructure ministry on Monday.

Russia has since October been targeting Ukraine's energy infrastructure with waves of missile and drone strikes.

Ukrainian Agriculture Minister Mykola Solsky said on Sunday that two other ports - Chornomorsk and Pivdennyi - that are authorised to export grains from Ukraine under a deal between Russia and Ukraine were partially operating.
