The U.S. military says it has successfully blocked 9 oil tankers heading to or from Iranian ports as part of President Donald Trump's blockade against Tehran.

The U.S. began enforcing the blockade 48 hours ago, and U.S. Central Command says no vessels have made it past U.S. forces.

"During the first 48 hours of the U.S. blockade on ships entering and exiting Iranian ports, no vessels have made it past U.S. forces. Additionally, 9 vessels have complied with direction from U.S. forces to turn around and return toward an Iranian port or coastal area," CENTCOM wrote in a statement on X.
