Nearly six months into the open conflict between the United States, Israel and Iran, the strategic Strait of Hormuz remains closed to most commercial and all military traffic, Tehran’s top diplomatic officials confirmed Wednesday, even as discussions with Oman over a proposed temporary transit corridor and joint mine-clearing operations move forward. The closure, which has already upended global energy markets by blocking roughly 20% of the world’s daily oil and liquefied natural gas exports, will remain in place until Washington fulfills its unmet commitments from a June bilateral memorandum of understanding, ends its military campaign against Iran and lifts harsh economic sanctions, Iranian Deputy Foreign Minister Kazem Gharibabadi told state news agency IRNA.
