Ukrainian sea drones yesterday hit and disabled a tanker involved in trading Russian oil as it sailed through Ukraine’s exclusive economic zone in the Black Sea to the Russian port of Novorossiysk, a Ukrainian official said.
The attack is the third sea drone strike in two weeks on vessels part of Russia’s so-called “shadow fleet” – unregulated ships which Kyiv says are helping Moscow export large quantities of oil and fund its war in Ukraine despite Western sanctions.
War insurance costs for ships sailing to the Black Sea have spiked, with insurers reviewing policies daily as the conflict in Ukraine spills into sea lanes.
The Dashan tanker was sailing at maximum speed with its transponders off when powerful explosions hit its stern, inflicting critical damage on the vessel, the official at the Security Service of Ukraine (SBU) said. He made no mention of possible casualties in the incident.
The strike on the Dashan, which is under European Union and British sanctions and is sailing without a known flag registry, was also confirmed by three maritime security sources.
There was no immediate comment from Russia on the incident.
Naval drones could be seen speeding towards the hulking tanker followed by powerful explosions as they reached it, video footage provided by the official showed.
Reuters was able to verify it was the Dashan tanker in the video by comparing the deck, cranes and structures with file imagery. The location and date were confirmed by the SBU source’s account and ship tracking data.
“The SBU continues to take active measures to reduce petrodollar revenues to the Russian budget,” said the official.
“Over the past two weeks, this is the third tanker of the shadow fleet put out of action that had helped the Kremlin circumvent international sanctions.”
Russian President Vladimir Putin threatened last week to sever Ukraine’s access to the Black Sea in response to the attacks on tankers, which he derided as piracy.
Ukraine has been attacking Russian oil refineries for months, using long-range aerial drones to strike far behind the front lines of Moscow’s war against Ukraine.
The strikes on the tankers represent a different line of attack. There have been at least seven blasts on other tankers that called at Russian ports since December 2024 at locations including in the Mediterranean.
Ukraine is suspected of carrying out those attacks using limpet mines, maritime security sources said, but Kyiv has not confirmed or denied any role.
l European leaders say “intensive work” will continue in the coming days on a US-led plan to end the Russia-Ukraine war, after a joint phone call with President Donald Trump.
UK Prime Minister Sir Keir Starmer, French President Emmanuel Macron and German Chancellor Friedrich Merz said they “agreed that this was a critical moment – for Ukraine, its people and for shared security across the Euro-Atlantic region”.
A White House official confirmed the call took place yesterday but did not give details. It comes the day after Trump called European leaders “weak”, suggesting the US could scale back support for Ukraine.
Zelenskiy said yesterday he had discussed with Ukraine’s parliament legal and other issues linked to the possibility of holding an election and urged other countries, including the US, not to apply pressure on the issue.
“If partners, including our key partner in Washington, speak so much and so specifically about elections in Ukraine, about elections under martial law, then we must provide legal Ukrainian answers to every question and every doubt,” he said in his nightly video address.
“It is not easy, but pressure on this issue is definitely not what we need.”
