Hezbollah and Iran have emerged bruised from separate conflicts with Israel in November and June, respectively. Now, Beirut’s instruction for Hezbollah to disarm risks further undermining the relevance of the group at a critical time, analysts said.

The visit by Ali Larijani, the head of Iran’s top security body, came as the Lebanese government moves to disarm Hezbollah, the militant group that has long been Tehran’s most powerful regional ally.

Lebanon’s president has told a top Iranian security official that Beirut rejects foreign intervention and wants stability for its people.
