A significant oil spill originating from a damaged tanker is currently washing ashore along the United Arab Emirates (UAE) coastline. The incident, which follows a vessel strike near the Strait of Hormuz earlier this month, has forced authorities to close several beaches and coastal sections. Satellite imagery reviewed by BBC Verify indicates that the oil slick had spread more than 35 kilometres from the vessel by Wednesday.
The source of the pollution has been identified through satellite analysis as the Panama-flagged crude oil tanker Gem No.2. According to maritime intelligence firm Vanguard, the vessel was struck by an unknown projectile on October 9, just north of Al Jazeera Al Hamra. This strike triggered a fire on board that was captured in verified footage, showing plumes of black smoke rising over the ship and crew members evacuating the deck. The Indian consulate in Dubai confirmed on October 11 that all 22 Indian crew members were successfully rescued following the incident.
UAE authorities confirmed on Thursday that the environmental impact is clearly visible, with verified footage from Friday showing oil coating the water and reaching the shoreline near the northern city of Umm Al Quwain. In response, the UAE's Ministry of Climate Change and Environment has initiated containment measures aimed at limiting further ecological damage. While initial evidence of a leak appeared as early as October 19, radar imagery confirms the slick expanded rapidly over the subsequent two days.
The spill has raised urgent concerns among researchers due to its proximity to the Siniyah and Khor Al Beidah islands. This region is a globally recognised Key Biodiversity Area, supporting vital ecosystems such as saltmarshes, seagrasses, and corals. The area serves as a habitat for protected species, including green turtles and the critically endangered Halavi guitarfish. Scientists at the Conflict and Environment Observatory have flagged this geographical intersection as a primary environmental concern.
Professor Steve Widdicombe, director of the Sharjah Marine Science Research Centre, stated that environmental impact is inevitable, though the full extent of the damage remains difficult to quantify at this early stage. The long-term consequences, he noted, will depend on factors such as the type of oil, the effectiveness of the ongoing clean-up, and the speed at which the substances evaporate or break down. Beyond immediate physical threats, such as the smothering of seabirds or damage to fish gills, toxic compounds could have persistent effects on the reproductive health of local marine life.
The strike on the Gem No.2 is part of a broader, record-breaking surge of vessel attacks in and around the Strait of Hormuz throughout October. Security analysts suggest these incidents are linked to Iranian efforts to exert greater control over the vital shipping lane, occurring in the context of increased US military activity in the region. Iranian state media claimed the tanker was using an unauthorized route when it was hit, later broadcasting footage that appeared to show the vessel on fire with oil leaking into the sea.
As clean-up operations continue, regional experts are monitoring the situation closely to prevent further degradation of the coastline. This incident follows a similar environmental event in August, when an oil slick affected Iran's Qeshm Island, highlighting the ongoing risks to marine ecosystems in the face of maritime conflict in the region. Further assessments of the UAE coastline are expected as authorities continue to evaluate the containment progress.
