Jornal Do Brasilia - Ukraine attack hits Russian warship at Black Sea base

The number of attacks in the sea has increased from both sides since Moscow exited a deal last month that had allowed Ukrainian grain exports via the shipping hub during the conflict between the two countries.

In a video of the attack obtained by AFP, a naval drone is seen speeding towards the darkened silhouette of a military vessel before the connection abruptly cuts off.

A Ukrainian attack targeting the Olenegrorsky Gornyak landing ship in the Novorossiysk naval base in southern Russia was "succesful", a Ukrainian security source told AFP Friday.

"The goal was to show that Ukraine can attack any Russian warship in that zone," the source added.

Russia said it had repelled an attempted attack on the base by the Ukrainian armed forces "with the use of two unmanned sea boats".

Russia's Black Sea Fleet has been targeted since the beginning of Moscow's military campaign in Ukraine more than a year ago, but attacks have increased in recent weeks.

"The presence of the Russian fleet in the Black Sea... will be put to an end," Ukrainian presidential aide Mykhailo Podolyak said on social media following the most recent drone strike.

"Ukraine will ensure freedom and security in the Black Sea for world trade."

The port of Novorossiysk also hosts the terminus of a pipeline that carries most Kazakh oil exports through Russia.

The fuel artery's operator Caspian Pipeline Consortium said it was continuing to ship oil to moored tankers at the terminal, Russian state media reported Friday.

- Crimea attack -

The Russian defence ministry meanwhile said it had downed 13 drones over the Crimean peninsula, without recording casualties or damage.

Crimea, annexed by Russia in 2014, has been targeted by Kyiv throughout Moscow's Ukraine offensive but has seen more intense attacks in recent weeks.

Ukrainian drone strikes on Crimea in July blew up an ammunition depot and damaged a strategic and symbolic bridge linking Russia's mainland to the peninsula.

Earlier this week, Russia's defence ministry said it foiled a Ukrainian drone attack targeting patrol boats in the Black Sea.

Three drones were trained on ships navigating in waters 340 kilometres (210 miles) southwest of Sevastopol, the base of Russia's Black Sea fleet in Crimea.

Also announced Friday was Russian Defence Minister Sergei Shoigu's visit to a combat zone in Ukraine to inspect a command post and meet senior military officers.

Shoigu got an update on the situation on the front and "thanked commanders and soldiers... for successful offensive operations" in Lyman in eastern Ukraine, the army said, without mentioning when the visit took place.

Shoigu last visited the front at the end of June after an aborted rebellion by the Russian paramilitary group Wagner fighting along with Moscow's forces in Ukraine.

Ukraine began its long-awaited counteroffensive in the same month but has made modest advances in the face of stiff resistance from Russian forces on the front line.

Ukrainian President Volodymyr Zelensky said Thursday that the counteroffensive was difficult, reporting "very violent" fighting in the key areas on the eastern and southern fronts.

Late summer and early autumn 2022, Ukraine retook swathes of territory around Kherson and Kharkiv in rapid counteroffensives.

In the southern sector, Ukrainian troops were "gradually but persistently moving forward", deputy defence minister Ganna Malyar said on Telegram.
