Failaka Island
On 23 January, Iraq dumped of crude oil into the Persian Gulf, causing the largest offshore oil spill in history at that time. It was reported as a deliberate natural resources attack to keep US Marines from coming ashore ("Missouri" and "Wisconsin" had shelled Failaka Island during the war to reinforce the idea that there would be an amphibious assault attempt). About 30–40% of this came from allied raids on Iraqi coastal targets.
