Russian overnight drone attacks damaged Slovakia-, Palau- and Liberia-flagged vessels in ports in Ukraine's Odessa and Mykolaiv regions, Ukraine's deputy prime minister said on Friday.
In recent weeks, Russia has escalated attacks on the southern Odesa region, and Ukrainian officials said Moscow aimed to cut Ukraine off from the Black Sea and sow chaos among civilians.
There were no casualties in Friday's strikes, Oleksiy Kuleba said in a statement on a social media messaging app, but the attacks caused power cuts and damaged elevators and civilian warehouses in the Odesa region.
Separately, Kuleba added, drones damaged a locomotive and a freight car at the northwestern Kovel railway station, around 60 kilometres from Poland.
"Despite Russia's deliberate terror, Ukraine's logistics system continues to function," Kuleba said. Russia did not comment on the matter.
On Thursday, two oil product tanks caught fire at the southern Russian port of Temryuk after what authorities in the Krasnodar region said was a Ukrainian drone attack. The fire has since been put out, officials said.
