IDF hits Assembly of Experts during vote

The IDF hit the Assembly of Experts headquarters while the body chose Ali Khamenei's successor. Members of the constitutional body were among the casualties.

ConflictDeveloping
Key takeaway

Striking a constitutional deliberative body mid-session is without clear modern precedent in the laws of armed conflict, creating legal ambiguity that both sides will exploit and that sets a potentially destabilising international norm.

The IDF struck the Assembly of Experts headquarters in Tehran on Tuesday while the body was meeting to choose a successor to Ali Khamenei. Multiple members were killed or wounded, according to Israel Hayom and Middle East Eye. Iranian state media claimed the Building had been evacuated before the strike — a claim that cannot be independently assessed while Iran's internet blackout holds connectivity at 1% of normal levels . No foreign journalists are operating inside Iran.

The timeline of the succession vote relative to the strike is unresolved. Whether the Assembly voted before the strike, in its chaotic aftermath, or reconvened in a dispersed emergency session at an alternate location has not been established by any source with direct knowledge. The Assembly's headquarters in Tehran had already been struck during the campaign's opening hours , when Chatham House analyst Sanam Vakil assessed that the body might not convene until operations wound down. It convened anyway — and was hit again.

The strike fits an established pattern of targeting Iran's institutional infrastructure. The IRGC's Sarallah headquarters, state broadcaster IRIB's Tehran offices , and now the body constitutionally responsible for choosing The Supreme Leader have all been struck. President Trump stated that Iran's "new leadership" had been specifically targeted . The progression from military sites to the state broadcaster to the succession body itself represents the systematic dismantling of institutional capacity — command, communications, and now political continuity.

Targeting a constitutional body during a succession process has no direct precedent in the conflict between these states. Iran's last leadership transition — when Ali Khamenei succeeded Ruhollah Khomeini in June 1989 — occurred peacefully, within hours of Khomeini's death, by a body that was intact and uncontested. This succession occurred under bombardment, in a communications blackout, with members of the selecting body among the casualties. Whether the strike was timed to disrupt the vote or coincided with it through operational scheduling is unknown. The effect on the legitimacy of the outcome is the same.

Deep Analysis

In plain English

The Assembly of Experts is Iran's body of senior clerics that — constitutionally — appoints and can remove the Supreme Leader. Israel struck their headquarters while they were in the middle of choosing Khamenei's successor. It is roughly equivalent to bombing a parliament during a vote to elect a new head of state. Whether that makes it a legitimate military target — on the grounds that the successor would command Iran's war effort — or an attack on a civilian constitutional institution is genuinely contested under international law. Both Iran and its adversaries know the legal ambiguity and will use it to their respective advantage.

Deep Analysis
Root Causes

Israeli targeting doctrine since the 2006 Lebanon war — the 'Dahiya doctrine' — holds that civilian infrastructure used for strategic purposes becomes a legitimate military target. The IDF appears to have assessed the succession deliberation itself as a strategic military decision, treating the identity of the next Supreme Leader as operationally relevant to Iran's conduct of the war and the Experts' session as therefore targetable.

Escalation

The strike's operational outcome may have achieved the inverse of IDF intent: by disrupting the succession process, it appears to have accelerated a rushed, constitutionally invalid result producing a Supreme Leader wholly dependent on the IRGC with no internal clerical counterweight — removing the moderating pressures on Iranian war strategy more effectively than simply killing Experts members would have.

What could happen next?
  • Consequence

    The strike's acceleration of the succession process — producing a constitutionally contested result under duress — may have handed Iran a propaganda narrative of Israeli interference in Iranian sovereignty that strengthens domestic support for the new leadership among populations otherwise sceptical of dynastic succession.

  • Risk

    If the succession vote is later characterised as coerced or constitutionally void, it creates a legal and political pretext for internal power struggles or rival factions to contest Mojtaba's authority.

    Medium term · Suggested
  • Precedent

    Striking a constitutional deliberative body during a succession process sets a norm other state actors could invoke to justify targeting legislative or constitutional institutions during armed conflict.

Different Perspectives
NATO eastern flank (B9 + Nordics)
NATO eastern flank (B9 + Nordics)
The B9+Nordic Bucharest joint statement on 13 May reaffirmed Ukraine's sovereignty within internationally recognised borders and backed NATO eastern flank reinforcement; the summit accepted Zelenskyy's bilateral drone deal proposal as a structural alternative to the stalled US export approval pathway, treating it as a European defence architecture question rather than aid delivery.
IAEA / Rafael Grossi
IAEA / Rafael Grossi
Grossi is still negotiating a sixth ZNPP repair ceasefire with no agreement after 50 days of 750 kV line disconnection; the 3 May ERCL drone strike that destroyed environmental monitoring equipment represents a qualitative escalation in infrastructure degradation that the IAEA has documented but cannot compel either party to halt.
Péter Magyar / Hungary
Péter Magyar / Hungary
Magyar's incoming foreign minister pledged on 12 May that Hungary will stop abusing EU veto rights; the pledge is a statement of intent rather than a binding legal commitment, and Magyar's MEPs voted against the €90 billion loan as recently as April, while a planned referendum on Ukraine's EU accession preserves a downstream blocking lever.
EU Council and European Commission
EU Council and European Commission
The Magyar cabinet formation on 12 May removes the Hungary veto that had blocked the €9.1 billion first tranche since February; the Commission is now coordinating the three-document disbursement package for an early-June vote. The structural blocker is gone; the disbursement question is now scheduling, not politics.
Donald Trump / White House
Donald Trump / White House
Trump announced a 9-11 May three-day ceasefire with a 1,000-for-1,000 prisoner exchange attached, then called peace 'getting very close' on 11-13 May while Russia's 800-drone barrage was under way; his public framing adopted Russian diplomatic language without securing any Russian operational concession or verifying the exchange was agreed.
Vladimir Putin / Kremlin
Vladimir Putin / Kremlin
Putin told reporters on 9 May the war is 'coming to an end' while Peskov confirmed on 13 May that territorial demands are unchanged and Russia requires full Ukrainian withdrawal from all four annexed regions; the verbal accommodation costs Moscow nothing and conditions any summit on a pre-finalised treaty Kyiv cannot accept.
