An oil spill from the stricken tanker Caroline Bezengi has reached Oman's coast, Omani authorities said, in one of the larger shadow-fleet pollution events to hit the region [1].
The Caroline Bezengi sails under Cameroon's flag and carries sanctioned Russian crude as part of what analysts call Russia's shadow fleet, the loose network of aging, opaquely owned tankers used to move oil around Western restrictions. It has been disabled since a suspected explosion on June 8, 2026, and is subject to EU, UK, Swiss, Canadian, and Ukrainian sanctions [1].
The vessel was carrying an estimated 800,000 barrels of crude, and the resulting slick now covers roughly 400 square kilometers, about 154 square miles [1]. Up to 40 kilometers of Oman's mainland coastline, particularly near Ras Madrakah, has been affected, with a further 10 to 20 kilometers of Masirah Island's shore expected to be hit within hours [1].
Greenpeace and other environmental groups say the spill is significantly larger than Oman's official estimate [1]. The slick is concentrating around the Hallaniyat archipelago, home to a marine reserve established in 2025 to protect sea turtles and their habitat [1].
The harder problem is who pays. Because shadow-fleet tankers are structured to evade standard pollution-liability rules, there may be no one on the hook for the response. Oil-spill expert Christopher D'Elia told Al Jazeera, "there is no responsible party" to finance the cleanup, noting that these vessels sit outside the liability frameworks that would normally fund it [1].
The tanker lies in waters where regional shipping has been under strain, but Al Jazeera's report does not link the spill to any Hormuz blockade or to Iran, and no such connection is established here [1].
