CNN has identified the vessel as the bulk carrier Matros Pozynich.

From Sevastopol, according to satellite images and tracking data reviewed by CNN, the Matros Pozynich transited the Bosphorus strait and made its way to the Egyptian port of Alexandria. It was laden with nearly 30,000 tons of Ukrainian wheat, according to Ukrainian officials.

The Matros Pozynich is one of three ships involved in the trade of stolen grain, according to open-source research and Ukrainian officials.

But the Ukrainians were one step ahead

Officials say Egypt was warned that the grain was stolen, and the shipment was turned away. The Matros Pozynich steamed toward the Lebanese capital of Beirut with the same result. The ship turned off its transponder again on May 5, but imagery from and Maxar Technologies shows it traveled to the Syrian port of Latakia.

Crimea, annexed by Russia in 2014, produces little wheat because of a lack of irrigation. But the Ukrainian regions to its north, occupied by Russian forces since early March, produce millions of tons of grain every year. Ukrainian officials say thousands of tons are now being trucked into Crimea.
