Ukraine said on Tuesday that another 11 Russian vessels have been targeted in the Sea of Azov in overnight strikes.

Kyiv's drone forces commander, Robert Brovdi, known by his callsign "Magyar", said in a statement on Telegram that the targets included five tankers, five cargo vessels and one tugboat.

He said the aim was to damage Russia's so-called "shadow fleet" and to limit Russia's fuel supplies to Moscow-controlled Crimea.

The Reuters news agency reported that shipping in the area remained restricted on Tuesday, citing unnamed sources.A vessel is seen in this screen grab taken from undated drone footage which Ukrainian authorities said showed an attack on a Russian vessel at seaImage: Commander of Unmanned Aerial Systems Force/Handout/REUTERS
