(Reuters) -A&nbsp;Russian&nbsp;warship&nbsp;was seriously&nbsp;damaged&nbsp;in an overnight&nbsp;Ukrainian&nbsp;naval&nbsp;drone&nbsp;attack&nbsp;on Russia's Black Sea navy&nbsp;base&nbsp;at&nbsp;Novorossiysk, the first time the&nbsp;Ukrainian&nbsp;navy has projected its power so far from the country's shores.
The port, which handles 2% of the world's oil supply and also exports grain, temporarily halted civilian ship movement before resuming normal operations, according to the Caspian Pipeline Consortium which operates an oil terminal there.
Russia's Defence Ministry said a&nbsp;Ukrainian&nbsp;attack&nbsp;by two sea drones had been repelled in the waters outside the&nbsp;base&nbsp;and that the drones had been destroyed. It made no mention of any damage in its short statement.
A&nbsp;Ukrainian&nbsp;intelligence source said the Olenegorsky Gornyak, a&nbsp;Russian&nbsp;Navy landing ship with around 100&nbsp;Russian&nbsp;servicemen on board, had been hit by a sea drone carrying 450 kilograms of TNT.
"As a result of the&nbsp;attack, the Olenegorsky Gornyak received a serious breach and currently cannot conduct its combat missions," the source told Reuters, adding that the operation had been carried out by Ukraine's Security Service and the navy. "All the&nbsp;Russian&nbsp;statements about a 'repelled&nbsp;attack' are fake."
Video footage verified by Reuters showed the Olenegorsky Gornyak being towed to shore by a tug, listing heavily to its port side.
Andriy Ryzhenko, a retired&nbsp;Ukrainian&nbsp;Navy captain and&nbsp;naval&nbsp;consultant, estimated the sea drones had travelled 740 km (460 miles) from their likely launch area to&nbsp;Novorossiysk, which would amount to a significant increase in their range.
"It was the first time ... the&nbsp;Ukrainian&nbsp;navy projected power so far away," he said.
A source with knowledge of the port's operations said a large&nbsp;Russian&nbsp;naval&nbsp;vessel had to be towed ashore because it could not move under its own power after being&nbsp;damaged.
The source, who did not name the vessel, said oil and grain loadings were still taking place at the port, which resumed normal operations hours after the&nbsp;attack.
Ukraine referred to the Olenegorsky Gornyak without directly claiming responsibility for the&nbsp;attack.
"We have open information that it is indeed&nbsp;damaged," said Natalia Humeniuk, spokesperson for the southern military command said, adding "it is absolutely legal to destroy the potential of the enemy in time of war."
The Kremlin referred questions to the defence ministry, which did not immediately respond to a request for comment.
The&nbsp;Ukrainian&nbsp;source shared a grainy video that looked like it had been shot from the top of a maritime drone that sails right up to the side of a large vessel before the video abruptly cuts out and turns to pixels.
"Another&nbsp;Russian&nbsp;ship is teetering, undermining the aggressor's security reputation in the Black Sea waters," Ukraine's foreign ministry said on X, previously known as Twitter, adding that one of its compartments had flooded.
Andrei Kravchenko, a&nbsp;Novorossiysk&nbsp;city official, said on the Telegram app that the Olenegorsky Gornyak was one of two ships that had "instantly reacted" to fend off the&nbsp;Ukrainian&nbsp;attack.
RISING BLACK SEA TENSIONS
Russian&nbsp;social media users had reported hearing explosions and gunfire near&nbsp;Novorossiysk&nbsp;on Friday morning.
"Tonight, the armed forces of Ukraine attempted to&nbsp;attack&nbsp;the&nbsp;Novorossiysk&nbsp;naval&nbsp;base&nbsp;with two unmanned sea boats," the Defence Ministry said in its statement.
"In the course of repelling the&nbsp;attack, the unmanned boats were visually detected and destroyed by fire from the standard weapons of the&nbsp;Russian&nbsp;ships guarding the outer waters of the&nbsp;naval&nbsp;base."
The Caspian Pipeline Consortium which loads oil onto tankers in&nbsp;Novorossiysk&nbsp;said its facilities had not been&nbsp;damaged&nbsp;and that oil loadings continued onto tankers which were already moored.
The port is one of the biggest in the Black Sea, and a major terminal for the export of oil and oil products. The Caspian Pipeline Consortium is the main exporter of Kazakh crude oil.
Exports of&nbsp;Russian&nbsp;and Kazakh oil from&nbsp;Novorossiysk&nbsp;average around 1.8 million barrels per day, or about 2% of global oil supply.
Britain's military intelligence service said last September that Russia's Black Sea Fleet had relocated some submarines from the Crimean port of Sevastopol to&nbsp;Novorossiysk, probably because of the increased threat of&nbsp;Ukrainian&nbsp;long-range strikes.
Retired&nbsp;Ukrainian&nbsp;Navy captain Ryzhenko said the drone video suggested the&nbsp;Russian&nbsp;vessel had been taken by surprise.
"Open windows were visible with the lights on inside. No sailors on the top deck (were) looking for a possible threat. This drone just hit in the middle and caused significant damage to this ship," he said.
"This is quite a serious signal to Russia that other&nbsp;attacks can be conducted and for them it will be unsafe to keep vessels even in&nbsp;Novorossiysk."
Tensions in and near the Black Sea have escalated since Russia last month withdrew from a deal allowing the safe export of grain from&nbsp;Ukrainian&nbsp;ports.&nbsp;Russian&nbsp;drones and missiles have since repeatedly struck&nbsp;Ukrainian&nbsp;port facilities and grain silos on or near the Black Sea.
Ukraine sank Russia's flagship, the cruiser Moskva, in April 2022 and said in June last year that it had hit a&nbsp;Russian&nbsp;naval&nbsp;tugboat with Western-supplied anti-ship missiles.
The&nbsp;Ukrainian&nbsp;source did not mention other&nbsp;attacks on&nbsp;warships, but said Friday's hit was the latest in a string of successful operations by the security service, including sabotage operations on Russia's bridge to occupied Crimea last year and last month.
The&nbsp;Russian&nbsp;Defence Ministry said on Friday that its forces had also repelled an attempted&nbsp;Ukrainian&nbsp;attack&nbsp;on Crimea, which it annexed from Ukraine in 2014, using at least 13 aeroplane-like drones. It said there were no casualties or damage.
