This is the best summary I could come up with:

Ukrainian President Volodymyr Zelenskyy on Wednesday hailed the first cargo ship to depart Ukraine using a new Black Sea corridor for civilian vessels.

“Ukraine has just made an important step toward restoring the freedom of navigation in the Black Sea,” despite warnings from Moscow that its navy could target vessels, Zelenskyy said on social media.

The ship successfully crossed the Ukrainian part of the Black Sea late Wednesday, several hours after leaving the southern port of Odesa.

Russia had warned that it could sink civilian vessels traveling to and from Ukraine after Moscow withdrew from a deal allowing the export of grain via the Black Sea.

As a sign of the risks involved, over the weekend a Russian warship fired warning shots at a cargo ship heading for Izmail, a port on the Danube in southern Ukraine directly opposite NATO and European Union member Romania.

Izmail has become one of the main exit routes for Ukrainian agricultural products since Moscow ended the agreement on grain exports, a source of revenue for Kyiv, in July.
