Israel Destroys Assembly of Experts Meeting Site — Iran's Succession Crisis Deepens

The Wartime Report · Published March 20, 2026

Summary

Israeli strikes destroyed the building where Iran's Assembly of Experts was expected to convene to select a successor to the slain Supreme Leader Khamenei. The strike deepened Iran's leadership crisis and signaled that the coalition was actively working to prevent the regime from reconstituting itself. In Lebanon, sweeping Israeli evacuation orders began across the south as Hezbollah sustained barrages of over 100 rockets in single evenings.

Military Developments

Assembly of Experts Building Destroyed

In one of the most politically significant strikes of the war, Israeli forces destroyed the building where Iran's Assembly of Experts was expected to meet to select a new supreme leader. The 88-member clerical body is the only institution constitutionally empowered to choose Khamenei's successor. By striking the meeting site, Israel effectively disrupted the succession process, extending the power vacuum at the top of the Iranian state.

The strike on the supreme leader council gathering was widely seen as crossing the line from military to political warfare — an attempt not just to degrade Iran's military capability but to prevent its government from functioning.

Lebanon Escalation

The situation in Lebanon deteriorated rapidly:

Sweeping evacuation orders — Israel issued broad evacuation orders across southern Lebanon, a harbinger of intensified operations
Hezbollah barrages — The group launched sustained rocket attacks, with over 100 rockets fired in single evenings
Israeli air strikes — Continued targeting Hezbollah infrastructure throughout Lebanon

Gulf State Attacks Continue

Iran continued to attack Gulf state infrastructure, maintaining pressure on the nations that host U.S. military bases and assets.

Political Developments

Iran's Power Vacuum

With Khamenei dead and the Assembly of Experts unable to convene, Iran faced an unprecedented constitutional crisis. The Supreme Leader holds ultimate authority over all branches of government, the military, and the nuclear program. Without a successor, command authority was fragmented and contested — precisely the outcome the coalition sought.

Lebanon's Civilian Crisis Begins

Israeli evacuation orders in southern Lebanon signaled that a broader military operation was being prepared. Civilians began fleeing north, triggering what would become one of the largest displacement crises in the region.

Economic Impact

Iran's continued attacks on Gulf state infrastructure kept energy markets on edge. The inability to form a new Iranian government also raised questions about who, if anyone, could negotiate a ceasefire or surrender — potentially prolonging the conflict and its economic toll.

International Reaction

Iran — The regime struggled to project authority and continuity with its leadership decimated and succession blocked
Gulf states — Continued to absorb Iranian retaliatory strikes while reinforcing air defenses
Lebanon — Faced a growing humanitarian crisis as evacuation orders displaced thousands from the south
Analysts — ISW assessed that the Assembly of Experts strike crossed a line from military to political warfare
