Oman reports that a leaking tanker has discharged crude oil into the sea off the coast near a nature reserve, spreading into a slick covering roughly 390–400 square kilometres. The Environment Authority says the spill is about 390 square kilometres, while other reporting cites a figure close to 400 square kilometres. Authorities say the slick lies northeast of the Hallaniyat Islands and is within several kilometres of the coast.
The tanker, the Caroline Bezengi, is carrying close to one million barrels of Russian crude bound for Asia. It first reported difficulties on June 8 off Yemen, according to maritime sources cited by Reuters, with initial assessments indicating an onboard blast. No party has publicly taken responsibility for any attack, and it remains unclear what caused the vessel to ground. Oman says it is responding to protect facilities in the area, including desalination and tourism operations.
Some outlets also describe the spill’s wider estimated size using satellite-based assessments, with Greenpeace estimating a larger area (about 600 square kilometres). Reporting further notes the tanker is linked to sanctions against Russia and has been described as part of Russia’s shadow fleet, though details of the incident and ownership have varied by outlet.
