A sanctioned tanker has grounded off Oman, with satellite images confirming a crude oil leak that has produced a growing 20-square-kilometre sheen reaching the shores of Qibliyah Island in the Hallaniyat Islands. The vessel lies near a marine protected area, and gradual leakage has occurred over the past week amid risks from the approaching monsoon season. Analyses differ on the role of sanctions, enforcement priorities, and liability mechanisms.
