A sanctioned Russian tanker, Kairos, is reported to have been damaged in an explosion near the Bosporus Strait in the Black Sea on 28 November. The vessel is linked to Moscow's so-called shadow fleet used to evade Western restrictions on Russia's energy exports.

Two oil tankers said to be part of Russia’s “shadow fleet” that evade sanctions were struck off Turkey’s Black Sea coast possibly by mines, drones or missiles, a senior Turkish official said Saturday.
