Tensions in the Gulf have escalated after Iran issued a series of warnings to the United States, threatening to target US warships operating in the Strait of Hormuz. Tehran rejected any proposal for a new shipping corridor, vowed to resist forced changes to maritime routes, and said future engagement with Washington would depend on a change in U.S. policy. Iran also warned that any naval blockade or military escalation would have “serious consequences,” raising fresh concerns over regional stability and global energy security.
