Satellite Images Reveal Massive Oil Spill Near Iran’s Key Kharg Island Export Hub
Washington: Satellite imagery has revealed a large suspected oil spill near Iran’s Kharg Island, one of the country’s most important oil export terminals, according to reports by Reuters and other international media outlets. The spill was detected through images captured between May 6 and May 8 by the European Union’s Copernicus Sentinel satellites.
Reuters reported that the slick stretched across nearly 45 square kilometres of water west of Kharg Island in the Persian Gulf. Analysts studying the images said the dark patch appeared visually consistent with oil contamination, though the exact source of the leak has not yet been officially confirmed.
Kharg Island plays a crucial role in Iran’s energy sector, handling around 90% of the country’s oil exports. Most of those shipments are believed to be destined for China. The island has also gained strategic significance amid rising regional tensions involving Iran, the United States and Israel.

Environmental researchers and satellite monitoring experts cited by Reuters suggested the spill may be among the most significant incidents recorded since the recent escalation of conflict in the region. However, newer satellite images reportedly did not show evidence of an active leak continuing into surrounding waters.
The cause of the suspected spill remains unclear. Analysts mentioned the possibility of damaged ageing infrastructure, underwater pipeline leaks or operational strain linked to ongoing geopolitical tensions in the Strait of Hormuz. Reuters noted that neither Iranian authorities nor US officials immediately commented on the satellite findings.
The discovery has raised concerns about environmental risks in one of the world’s most critical oil transit corridors. International observers continue monitoring the area as questions remain over the scale of the damage and its potential impact on maritime activity in the Persian Gulf.
