Trump says US Navy blockade halts Iranian shipping through Hormuz

US President Donald Trump has claimed the American military has effectively blockaded the Strait of Hormuz, preventing Iranian vessels from passing through the critical waterway. The assertion comes as Iran reports one of its supertankers struck a sea mine while attempting transit.

Trump stated that the US Navy's blockade operations have successfully stopped all Iranian ships from crossing the Strait of Hormuz, one of the world's most strategically important shipping channels. The remarks mark an escalation in tensions between Washington and Tehran over maritime security in the Persian Gulf region.

Meanwhile, Iran's Islamic Revolutionary Guard Corps (IRGC) navy said a supertanker carrying over two million barrels of crude oil struck a sea mine while attempting to navigate through the strait. The incident underscores the volatile conditions in the waterway, which handles approximately one-third of global maritime petroleum trade.

The Strait of Hormuz, located between Iran and Oman, represents a critical chokepoint for international energy supplies. Any sustained disruption to shipping through the passage carries significant implications for global oil markets and regional stability, with particular concerns for Asian economies heavily dependent on Gulf energy resources.

The escalating military posturing between the United States and Iran in the Persian Gulf region has raised concerns among regional observers and international stakeholders about the potential for accidental escalation or broader conflict. Previous incidents involving Iranian and American naval forces in the strait have periodically triggered international alarm.
