Ukraine announced on Friday it is sending a third and fourth vessel through a temporary maritime corridor it set up to help trapped vessels get out of the war-torn country.

The Japanese-controlled, 178,000-dwt capesize Ocean Courtesy (built 2008) and the 58,000-dwt Anna-Theresa (built 2011) are the first vessels in the initiative to get out of the port of Yuzhnyy/Pivdennyi — a terminal closer to Russian arms than Odesa, from which the first two ships sailed last month.
