Strait Power Play and Hezbollah Tunnels Mark Iran-Israel Update

ISW-CTP report that Iran’s control of the Strait of Hormuz lets Tehran selectively allow passage and set fees, with signs it may discount tolls for friendly states like China, challenging free navigation under UNCLOS. In Lebanon, the IDF says it controls Hezbollah’s underground tunnel networks near Beaufort Castle and will continue operations, warning of a swift offensive if Hezbollah breaches the ceasefire, while urging the Lebanese Armed Forces to dismantle militant infrastructure under the June framework. UKMTO notes an attack on a bulk carrier off Hudaydah with no group claiming responsibility. There are no significant updates on US–Iran negotiations or US–Israel air campaign.
