[1/3] Cargo ship Despina V, carrying Ukrainian grain, is seen in the Black Sea off Kilyos near Istanbul, Turkey November 2, 2022.
The agreement, reached in July, created a protected sea transit corridor and was designed to alleviate global food shortages, with Ukraine's customers including some of the world's poorest countries.
So far, some 9.76 million tonnes of agricultural products have been shipped, predominately corn, but also volumes of soybeans, sunflower oil, sunflower meal and barley.
A drop in shipments from major exporter Ukraine has played a role in this year's global food price crisis, but there are also other important drivers.
At the start of the conflict there were around 2,000 seafarers from all over the world stranded in Ukrainian ports.
