Saudi state media say Riyadh has joined several other nations in an international effort to patrol the Strait of Hormuz and adjacent waters, where several commercial oil tankers have been impounded or harassed by Iran in recent months. “The Kingdom’s decision to participate is based on its declared support for regional and international efforts to deter threats to maritime safety,” the Saudi Press Agency said, citing an unnamed Defense Ministry source. “The Kingdom will work with its allies to ensure the security of energy routes and the continued flow of supplies to the global economy, and to maintain international peace and security.” The International Maritime Security Construct, led by the US and based in the Gulf, has up till now included naval assets from the US, UK, Australia and Bahrain. Earlier this week, Iran said it had seized a vessel it claimed was “smuggling” diesel fuel to the United Arab Emirates. In July, it seized a British-flagged tanker, the Stena Impero, which it says could be released soon.
