A vast oil spill from a leaking tanker reached Oman’s coastline on Wednesday, its environment agency said.<br>This oil spill threatens to become one of the world’s worst in years after spreading largely unchecked for several weeks, experts say.
On Monday, Oman said it was working to contain the spill, which had by then affected roughly 390 square kilometres (150sq miles), according to analysis by the country’s environment agency.<br>The slick now covers an area of more than 2,000sq km (770sq miles), said John Amos, an oil spill specialist who reviewed satellite imagery obtained by Reuters. It could affect about 40km (25 miles) of coast near Ras Madraka, as well as Masirah Island, Oman’s Environment Authority said.<br>Here’s what we know.<br>What happened?<br>Oil has been leaking from the tanker Caroline Bezengi since it ran aground about 22 nautical miles (41km) from the Omani coastal town of Sharbithat some time after the crew reported a suspected explosion on June 8. It had been en route from Russia to India.<br>Reuters reported that the tanker was carrying an estimated 800,000 barrels of sanctioned oil and that it ran aground on June 30.<br>An investigation by the news agency AFP found that the ship had been stranded for several weeks near Oman’s al-Qibliyyah Island.<br>In the meantime, the oil has been spreading towards Oman’s coastline.<br>The Oman News Agency (ONA) quoted the country’s environment authority saying that “today’s monitoring results showed that some beaches in the Ras Madrakah area were affected by oil pollution”.<br>Advertisement
The Indian Ocean town sits about 200km (125 miles) from al-Qibliyyah.<br>The slick is now concentrated around the Hallaniyat Archipelago off the southern coast, where a marine reserve was established last year to protect sensitive ecosystems home to diverse marine life, including rare sea turtles.<br>On Wednesday, the ONA reported that “a coastal stretch of up to 40 km in the [Ras Madrakah] area is expected to be affected”.<br>The southern beaches of Masirah Island, which lies 15km (nine miles) off the coast of Oman, could be contaminated “in the coming hours”, affecting a 10-20km (six-to-12-mile) stretch of coastline, it said.<br>An unnamed spokesperson for the United Nations International Maritime Organization said it was “closely monitoring” the leakage.<br>The damaged and half-sunk oil tanker Caroline Bezengi, at sea off the coast of Oman, on a date given as August 6, 2026 [Ambrey/Handout via Reuters]How did this happen?<br>British maritime security company Vanguard told AFP that the tanker had suffered “explosions” in early June as it sailed off the coast of Yemen, causing water to enter several sections of the vessel. It ran aground off the coast of Oman some time after this.<br>There has been no official explanation for the explosions and no party has claimed an attack. However, the vessel was navigating two separate wars on its journey from Russia to India. Tankers have been frequently targeted in the Gulf region in recent months as the US war on Iran has continued.<br>In April, the Caroline Bezengi sailed from the Russian port of Novorossiysk on the Black Sea, a flashpoint in the Russia-Ukraine war.<br>It is believed to be part of Russia’s “shadow fleet” used to circumvent Western sanctions on its oil exports. It last sailed under a Cameroonian flag.<br>Rentoor Shipmanagement and Villar Shipmanagement, both based in China, are registered as the ship’s owner and operator, respectively, according to the open-source database OpenSanctions.<br>Russia’s shadow fleet includes ageing vessels that have often been criticised for poor maintenance, lack of insurance and lacklustre safety standards.<br>Ukraine has previously carried out assaults on shadow fleet vessels believed to be carrying Russian oil.<br>The Caroline Bezengi then passed through the Suez Canal at the end of May, ship-tracking data shows, before sailing through the Red Sea and past Yemen, where the Iran-aligned Houthi fighters have entered a wider regional war between the United States, Israel and Iran and are targeting Saudi Arabia-flagged ships.<br>Advertisement
What damage could the oil spill cause?<br>Last week, advocacy group Greenpeace warned that the spill was on the verge of causing an “environmental disaster”.<br>Christopher D’Elia, a specialist in oil spills and a professor emeritus at Louisiana State University in the United States, told Al Jazeera the estimated 800,000 barrels of crude on board the...
