Iran has shifted to maritime routes to smuggle weapons to Hezbollah in Lebanon, bypassing traditional land routes due to instability in Syria, according to a Western security official. Two special Quds Force units are overseeing the operations, relying on direct maritime smuggling or intermediary countries. Hezbollah's control of the Port of Beirut facilitates the smuggling, with insiders helping to move equipment and weapons without inspection. The official also linked these smuggling efforts to the Beirut port explosion in 2020. The official warned of broader consequences for Lebanon and urged urgent action.
