Iran’s Islamic Revolutionary Guard Corps (IRGC) announced the closure of the Strait of Hormuz "until further notice" following an incident where a vessel allegedly traveling on an unauthorized route was struck. The IRGC claimed the ship had compromised maritime security by disabling its tracking systems and disregarded warnings. Tehran has threatened a "severe response" to any retaliation and warned that U.S. bases in the region could be targeted. This escalation comes as the U.S. demands the reopening of the waterway without tolls or interference. Diplomatic efforts involving Qatar, Pakistan, and Oman are reportedly underway to negotiate safe passage, though the status of these talks remains uncertain.
