Iran's navy claimed Thursday that four oil tankers had struck sea mines in the Strait of Hormuz. The U.S. Department of Defense has added two more service member deaths to its official account of casualties since the war with Iran started more than eight months ago. The Houthis denied any attempt to strike Saudi Arabia on Friday. Tankers strike mines in Strait of Hormuz, Iran says, as Hegseth fires top general. Saudi coalition says it intercepted Houthi drone in Mecca region. Could Hormuz mining claims raise U.S. fuel costs? There is no evidence of that yet. The reports establish a security risk, not a demonstrated U.S. price increase; rerouting, insurance and freight costs are possible transmission channels.
