Tensions between Iran and the United States have sharply escalated as Tehran reimposed restrictions on the Strait of Hormuz and warned it would continue blocking transit in response to the US blockade on Iranian ports. Iran’s Supreme Leader vowed that the navy would make the U.S. face “new defeats,” while Iranian forces reportedly fired on a tanker attempting to pass through the critical chokepoint. The standoff has disrupted maritime traffic, forced vessels to turn back, and raised fears of a deepening global energy crisis, even as mediators signal that a potential deal may still be within reach.
