BBC Verify has confirmed through satellite imagery and videos that a major oil slick has washed up on Iran's Qeshm Island, originating from an attack on the Minoan Pioneer bulk carrier in the Strait of Hormuz on August 3. The vessel, struck by a projectile in Omani waters, caught fire and began leaking fuel that spread across more than 300 square kilometers of the strait.

Environmental experts warn the spill threatens sensitive ecosystems including mangrove forests, coral reef habitats, and nesting sites for critically endangered Hawksbill turtles. John Amos, CEO of Skytruth, estimated the spill at well over 100,000 US gallons, calling it a "major oil slick." Dr. Keyvan Hosseini from the University of Southampton emphasized the location's vulnerability, noting Qeshm's importance as a fishing ground and habitat for marine life.

Maritime analysts believe Iran was likely responsible for the attack, describing it as a "self-inflicted wound." Since the US and Israel began striking Iran in late February, maritime intelligence company Kpler reports 67 vessel strikes in the area. A local environmental official claims the spill has been "almost completely cleaned up," though BBC Verify could not independently confirm this.

The Minoan Pioneer incident is part of a broader pattern of shipping disruptions in the region, including the sinking of the container ship Safeen Prestige in March, which also caused an oil slick. Experts note that such attacks pose ongoing environmental risks even when immediate spills are contained.
