Russian forces have also landed in the nearby Sea of Azov and could make further movements within the coming week, the statement added.
As well as being of strategic concern, the Black Sea is an important trade and travel route for Russia.
Ukrainian national security adviser, Oleksiy Danilov, said in an earlier televised speech that Russian paratroopers were preparing to enter Odesa, a port city on the Black Sea in southern Ukraine.
However, he said they would be met with fierce resistance by Ukrainian forces.
“They are awaited there, and they will have no smooth sailing,” he said, according to Ukrinform.
He also claimed an assault on the city was planned for last week by Russian forces but was postponed due to bad weather.
The video showed rocks being fired into the night sky before an orange glow appears, suggesting a destroyed vessel.
Then, Ukrainian soldiers can cheering and saying “we f******* hit them” and one repeated words heard by captured soldiers on Snake Island, saying: “Russian warship, go f*** yourself.”
The city of Odessa has not yet been attacked by Russian forces but residents have fortified the location and set up shelters and emergency services in preparation for a potential invasion.
