A suspected oil spill covering dozens of square kilometres of sea near Iran's main oil hub of Kharg Island has been seen on satellite imagery this week.
The likely spill - appearing on images as a grey and white slick - covered waters to the west of the 8-kilometre (5-mile) long island, pictures from Copernicus’s Sentinel-1, Sentinel-2 and Sentinel-3 satellites showed on May 6-8.
