Two oil slicks have emerged within Iranian waters, confirmed by satellite imagery and video footage verified by Reuters. These incidents occur amid escalating exchanges of attacks involving Iran and the United States targeting tankers and other ships, actions that hinder access for site assessment and environmental cleanup.
Off the coast of Oman, just outside the Strait of Hormuz, a grounded tanker named Caroline Bezengi is discharging Russian crude oil into a protected marine zone, resulting in a massive oil slick estimated at around 2,000 square kilometers. This spill is not directly connected to the ongoing regional conflict.
Inside the Gulf, one slick appeared near the southern tip of Qeshm Island, a prominent dolphin-shaped landmass in the Strait of Hormuz close to Iran. Satellite images from Copernicus’s Sentinel-2 shows the slick, with dark patches indicating heavy fuel oil, alongside a lighter, more diluted spill stretching approximately 160 kilometers. A video verified by Reuters shows a bubbling, dark liquid washing ashore on Suza Beach on Qeshm Island, contrasting sharply with the surrounding turquoise waters.
A second spill was identified near Sirri Island, a smaller landmass centrally located in the Gulf about 100 kilometers southwest of Qeshm, which hosts Iranian offshore oil and gas operations. The images of this spill were taken on August 13.
The Qeshm Island spill is believed to originate from the Minoan Pioneer, a Liberia-flagged dry bulk carrier. The vessel was struck near Oman’s coast on August 3 by an unidentified projectile, suspected to be part of an Iranian attack, resulting in the disappearance of one crew member. The leak from this incident appears to have contributed to the oil slick near Qeshm, according to maritime security sources.
Iran’s Foreign Ministry spokesperson, Esmaeil Baghaei, stated via X (formerly Twitter) that oil pollution from the Gulf had reached Qeshm Island and Preliminary investigations suggest that a foreign bulk carrier might be the source. However, Reuters has not independently verified the exact cause or substances involved in the slicks.
Efforts to assess and mitigate the spills face difficulties due to the ongoing conflict, with sources indicating that Iranian authorities have impeded rescue and cleanup operations, including the inability of a tugboat to reach the grounded vessel. Satellite experts warn that prolonged leakage increases the risk of widespread environmental damage to ecosystems and coastlines.
