Up to three other vessels used by an international oil and gas company for exports via the Black Sea were reportedly attacked

An oil tanker commissioned to transport crude from an internationally-owned terminal located at a Russian Black Sea port has been attacked by a drone, Kazakhstan's state-owned oil company KazMunayGas (KMG) reported on Tuesday.

The ship 'Matilda' was hit earlier in the day on its way to pick up cargo at the Caspian Pipeline Consortium (CPC) terminal this coming Sunday, the statement said. No crew members were hurt, KMG added, noting that the tanker remains seaworthy.

Reuters reported attacks on four tankers in the Black Sea that were on their way to the CPC terminal, located at the Russian port of Novorossiysk, including the 'Matilda', citing sources. The report suggested that Ukraine may have been responsible for the attacks, citing Kiev's history of targeting the consortium's assets in Russia, but said that Ukrainian officials have not commented on the situation.

CPC is a pipeline operator owned by Kazakh, Russian, and Western private firms and the government of Kazakhstan, which transports crude from the Tengiz oil field in Kazakhstan to the Novorossiysk terminal. The Russian military has in the past reported Ukrainian attacks on the infrastructure, as Kiev seeks to undermine Moscow's international oil trade.

Although Kiev does not officially claim credit for attacks on civilian infrastructure, the role of Ukrainian special services in several incidents has been broadly reported in domestic and international media. Moscow has described them as an element in a global Ukrainian campaign of sabotage and terrorism targeting Russian interests.
