Investing.com -- The Iran war spread towards the Red Sea and Caspian Sea over the weekend, despite the United States pausing its airstrikes after 13 consecutive nights of attacks, Reuters reported. Tensions shifted towards the Red Sea after Iran-aligned Houthi forces attacked Saudi Aramco facilities in Jizan and Yanbu. The Houthis have declared a naval blockade of Saudi Arabia and previously attacked two Saudi tankers in the Red Sea. The U.S. blockade and threats against Red Sea energy infrastructure leave global oil supplies exposed despite the temporary pause in direct attacks.
