Iran threatens Hormuz shutdown as Lebanon ceasefire falters

Iran's military command announced the closure of the strategic Strait of Hormuz on Saturday. Tehran cited a "clear breach of trust" by the United States regarding a 14-point memorandum of understanding, alongside ongoing Israeli violations of the ceasefire in southern Lebanon.
The Khatam al-Anbiya Central Headquarters stated that blocking the vital oil transit waterway represents a "first step" in response to these violations. Iranian officials warned of further military measures if regional operations continue.
Washington reports no physical disruption
US Vice President J.D. Vance stated that Washington has not yet confirmed any physical blockade of vessel traffic in the strait. The statement follows continuous military clashes between Lebanon-based Hezbollah and Israeli forces despite a recently declared truce.
Diplomatic channels open in Switzerland
Meanwhile, Tehran and Washington are moving toward direct diplomatic mediation. A spokesperson for the Iranian Foreign Ministry confirmed a delegation is traveling to Switzerland to monitor compliance with the bilateral memorandum.
The diplomatic track coincides with reports that US special envoy Steve Witkoff is also heading to Switzerland. Iranian state media maintained that Tehran has fulfilled its obligations and demanded that the United States compel Israel to halt its military actions in Lebanon.
