Giant Iranian oil tanker ' Grace 1' was seized in an illegal action by British Royal Marines in the Strait of Gibraltar on Thursday July 4. Apart from the fact that the tanker was on the right course and in international waters, even if Syria had been its destination, the British Royal Marines had no justification for seizing the tanker. Moreover, Britain has disrupted Iran's oil trade, in contravention of both the letter and spirit of JCPOA.
