A kamsarmax bulk carrier and a bunker tanker have been hit by shells while outside the port of Yuzhny, Ukraine.

The Moldovan Naval Agency, which runs the country’s ship registry, confirmed the 2,200-dwt Millennial Spirit (built 1974) was struck with a missile from an unknown source while sailing the Black Sea on Friday, while Ukrainian authorities suggested another ship was attacked.

The bunker tanker's crew of Russian nationals were being rescued by Ukrainian authorities and two are seriously injured.
