Iran’s Khatam al-Anbiya Central Headquarters issued a statement on Saturday announcing closure of the Strait of Hormuz, citing U.S. failure to implement the first article of a recent memorandum and Israeli ceasefire violations in Lebanon. The announcement followed Israeli strikes in southern Lebanon that killed over a dozen people hours after a U.S.-mediated ceasefire with Hezbollah took effect. Reporting is based primarily on Iranian state media and one U.S. outlet with limited independent confirmation of operational enforcement.
