A Greek-run oil tanker was attacked in the Black Sea after loading a Russian-origin cargo, Bloomberg reports.

The Suezmax-class Skiros, able to hold about 1 million barrels of oil, was attacked on August 16 after loading at the Caspian Pipeline Consortium’s (CPC) terminal near Novorossiysk, Russia, people familiar with the matter said.

In late July, the Financial Times (FT) reported, US Vice President JD Vance had asked Ukrainian President Volodymyr Zelenskyy to stop strikes on CPC infrastructure and tankers entering the port of Novorossiysk.

At the same time, according to FT, Kyiv had agreed not to strike CPC infrastructure and non-Russian ships unless they are under Ukrainian sanctions and are not transporting Russian oil or other Russian cargo.

The CPC is the main route for oil supplies from Kazakhstan. US companies Chevron and ExxonMobil, among others, have stakes in this consortium, reports the BBC. The CPC's marine terminal in Novorossiysk and tankers in its waters have been regularly attacked by Ukrainian forces. And after one of these attacks, Kazakhstan was forced to reduce oil production.
