The Iranian military has closed the Strait of Hormuz, citing Israel’s continued attacks on southern Lebanon as a violation of the recent US-Iran peace agreement. Tehran’s Revolutionary Guard Corps Navy warned vessels against approaching the waterway, stating security could not be guaranteed.
This strategic chokepoint handles approximately 20% of global oil and liquefied natural gas transit. Iran accuses Washington of failing to enforce the memorandum of understanding requiring immediate termination of military operations on all fronts. Tehran labeled the closure a direct response to broken promises regarding the Israel-Hezbollah ceasefire.
US Central Command disputed the severity of the blockade, reporting that safe passage remained intact with 55 merchant ships transiting recently. However, the announcement threatens the fragile diplomatic framework established days ago between US and Iranian leadership.
Israeli officials maintain their operations against Hezbollah are separate from the broader Iran agreement and have refused full withdrawal from Lebanon. Violence persists despite the nominal ceasefire, with airstrikes killing civilians in Barich just hours after the truce began.
Washington fears escalating tensions could collapse the peace deal entirely. Vice President JD Vance plans to travel to Switzerland for urgent negotiations, while Iranian diplomats intend to demand compliance with existing commitments. The strait previously faced closure in February, disrupting nearly $600 billion in annual energy trade.
