On June 20, 2026, Iran’s Khatam al-Anbiya Central Headquarters announced the closure of the Strait of Hormuz to vessel traffic, citing Israeli ceasefire violations in southern Lebanon and U.S. failure to implement an end-of-war agreement. A ceasefire between Israel and Hezbollah had been announced the previous day, followed by Israeli airstrikes on Nabatieh that the IDF linked to prior Hezbollah rocket launches. U.S. officials reported no observed military movements indicating an actual closure.
