Iran has declared its intention to close the Strait of Hormuz to all navigation, including oil tankers and commercial shipping, in response to recent military actions by the United States. The announcement, made by Iran’s top joint military command on Thursday, warns that any vessel attempting to transit the vital waterway will be targeted. The Strait of Hormuz is a critical chokepoint for global oil supply, facilitating a significant percentage of the world’s seaborne crude. This declaration escalates tensions in the Middle East following unspecified US attacks. The move raises concerns about potential disruptions to international trade and energy markets. Further updates are expected as the situation develops. The immediate impact on shipping routes and oil prices remains to be seen.
