The Greek-run oil tanker Skiros was attacked near Novorossiysk on 16 August 2026 after loading Russian crude at the Caspian Pipeline Consortium (CPC) terminal, Bloomberg reported.

The Suezmax-class vessel can carry about 1 million barrels. Bloomberg identified no attacker and provided no information about damage. Skiros’s Athens-based manager told the outlet that no one was injured and no pollution occurred.

CPC primarily exports Kazakh oil and carries more than two-thirds of Kazakhstan’s oil exports. Its shipments recently accounted for almost 2% of the global oil supply. Russian crude typically makes up only 5% to 10% of CPC exports.

Earlier in August, Ukraine agreed not to attack CPC infrastructure or non-Russian ships bound for the terminal if they were not under Ukrainian sanctions and did not carry Russian cargo. Because Skiros carried Russian crude, the protection did not apply to it under the terms Bloomberg described.

Following the July attacks, CPC considered suspending operations due to environmental and safety risks but decided to continue operations, Bloomberg reported.

The Skiros attack ended an almost three-week lull in attacks on ships using the terminal. Bloomberg did not say whether it disrupted oil loading, and CPC declined to comment.

Earlier attacks cut Kazakhstan’s oil production

Earlier attacks suspended loading at the terminal. Kazakhstan’s Energy Ministry confirmed a temporary reduction in oil production to prevent storage facilities from reaching capacity, while Reuters reported CPC loadings fell by a fifth in July.

The disruption also increased shipping and war-risk insurance costs as some operators became reluctant to call at the terminal, The Financial Times reported.

Paralysis of the logistics

Ukraine has not claimed responsibility for the Skiros attack, and Bloomberg did not identify an attacker. In a separate operation in July, the SBU and Navy acknowledged striking sanctioned Russian oil tankers Louise 1 and Banda with Mamai sea drones.

Robert “Madyar” Brovdi, commander of Ukraine’s Unmanned Systems Forces, later described the wider objective as the “paralysis of the logistics” of oil, fuel, and cargo that bypasses sanctions.

Romania detected more than 100 drones involved in seven attacks on Ukraine’s Danube ports in recent days, interim Romanian Defense Minister Radu Miruță told Romanian channel Digi24 on 17 August 2026. He said the attacks were the most intense recorded recently and that Ukrainian forces destroyed most of the drones “a few dozen meters from Romanian airspace.”

Russia’s growing attacks on Ukraine’s Danube ports put a key export route at risk as Kyiv seeks other outlets while its Black Sea ports are under attack. They also put Ukraine's southern border region under pressure as Kyiv develops trade links with Moldova and Romania, and NATO routes more military aid through Romania.

The latest drone swarms remained over Ukraine, and officials found no indication that Romania’s threat level had risen, Miruță stated. The Romanian military nevertheless remained on alert as attacks intensified across the Danube.

Ukraine looks south for trade and military aid

With Russia hitting its ports, Ukraine is turning to Romania and Moldova to keep trade moving. Kyiv and Chișinău are discussing a rail link through Moldova to Romania’s Constanța port, though Ukraine estimates it could carry only about 10% of its grain exports.

The rail proposal comes as Russian port strikes have cut monthly agricultural exports by 20–30% and left up to 10 million tons of grain in storage without buyers, Agriculture Minister Taras Vysotskyi has said.

More than 100 drones detected near Romania in four days, NATO jets scrambled seven times

NATO said in December that a second aid hub in Romania would begin operating in January. It was designed to supplement the main center in Rzeszów, Poland, and route supplies toward Ukraine’s southern and eastern fronts.

Romania faces repeated drone incursions

Russian drones targeting Ukraine have repeatedly entered Romania as Moscow attacks Ukrainian ports across the Danube. More than 40 such incursions had been recorded by early June, Romanian Foreign Minister Oana Țoiu said.

The most serious occurred on 29 May, when a drone hit an apartment building in Galați. Two people were injured, and about 70 residents fled or were evacuated.

Vladimir Putin suggested that the aircraft might have been Ukrainian, but Romania’s forensic investigation later identified it as a Russian-built Geran-2.

Romanian forces later shot down three drones in 72 hours in July, while Miruță said Spanish pilots and Romanian troops destroyed a fourth on 16 August.

Debris from drones intercepted over Ukraine has also washed onto Romania’s coast, prompting temporary access restrictions while specialists checked for explosives.

Bucharest is buying low-altitude radars and ground interceptors through the EU’s SAFE program. Miruță said drones often fly at 70 to 150 meters, and ground systems would be cheaper to use than fighter-launched missiles.
