Shipping companies have suspended services to Ukraine's Black Sea ports following mounting Russian attacks on the coast, officials said Thursday. According to the MarineTraffic monitoring website, no commercial ship entered a Ukrainian Black Sea port on Thursday morning. Ukraine's Foreign Minister Andriï Sybiga said Wednesday that no ship had taken Ukraine's Black Sea maritime corridor that day, "right at peak harvest". "In the last few days, the situation has become the worst since May 2022," said Odesa shipping broker Anton Shapran of the Martime Logistics firm.
