    Iran has announced a significant expansion of its claimed military control area around the Strait of Hormuz, asserting sovereignty over a key global trade route. This declaration, made by Iran's newly established "Persian Gulf Strait Authority," encompasses over 22,000 square kilometers (8,800 square miles), extending into the territorial waters of Oman and the United Arab Emirates.

    The expanded claim, which Iran states requires coordination and authorization for all transit, has been rejected by the United States and Gulf allies. The UAE described Iran's assertions as "fragments of dreams." This development follows an incident in early May where a Liberian-flagged tanker, Barakah, reported being struck by unknown projectiles in the Strait, with footage linked to Iran's Islamic Revolutionary Guard Corps (IRGC) claiming responsibility for a "punishment" strike.

    Concurrently, U.S. forces boarded an Iran-bound oil tanker, the Celestial Sea, in the Gulf of Oman on Wednesday, suspecting it of violating a U.S. blockade of Iranian ports. The U.S. military's Central Command (Centcom) stated it subsequently released the vessel after a search. Since the blockade's implementation on April 13, Centcom has redirected 94 commercial ships and disabled four vessels.
