A Liberian-flagged bulk carrier that was the second ship to sail from Odesa since Russia quit the Black Sea safe-transit deal has reached Romanian waters, said President Volodymyr Zelenskyy.

The Singapore-operated Primus had been in the port since February 20, 2022, with steel products for African countries, a senior Ukrainian government official said on Sunday.

Vice Prime Minister Oleksandr Kubrakov said the vessel blocked due to the war has left Ukraine’s Odesa port through a temporary Black Sea corridor, the second ship to do so since Russia withdrew last month from a U.N.-brokered deal that allowed for grain to be safely exported.

The information received has been confirmed by Ukrainian president Zelenskyy with a post on the social media platform Twitter.

“The second vessel has reached Romanian waters after successfully navigating through our temporary Black Sea corridor. It had been blocked since February 2022, loaded with steel for African consumers,” said Zelenskyy.

The Ukrainian president thanked everyone who made this possible, including the port workers, and “our warriors and everyone who defends freedom”, as he characteristically said.

“We defend freedom of navigation with real deeds and the world benefits from stability.”

Kubrakov said the ship had been at the port since Feb. 20, 2022, just before Russia’s invasion, and was carrying steel products to Africa.

He also confirmed that this is the second vessel blocked due to the war that has left the port of Odesa.

Britain warned last month that it has information indicating Russia’s military may start to target civilian shipping in the Black Sea, as Shipping Telegraph reported in July.

“Russia may expand their targeting of Ukrainian ports including attacks against civilian shipping in the Black Sea,” said Ambassador Barbara Woodward, UK´s permanent representative to the UN.

Russia threatened to treat all vessels as potential military targets after pulling out of the grain deal.

In response, Ukraine announced temporary corridors in the Black Sea for merchant vessels heading to and from Ukrainian ports.

We are now discussing alternative grain export routes, said recently Volodymyr Zelenskyy.
