Ali Larijani Killed, Israel Invades Lebanon — Decapitation Campaign Claims Iran's De Facto Leader

The Wartime Report · Published

Summary

Day 18 brought two seismic developments. First, Ali Larijani — the pragmatic senior official who had emerged as Iran's de facto leader after Khamenei's death and who was instrumental in negotiating the original JCPOA nuclear deal — was killed in a coalition strike. Second, Israel launched a limited ground invasion of Lebanon, opening a new front in an already sprawling conflict. The head of Iran's Basij militia, Gholamreza Soleimani, was also killed.

Military Developments

Ali Larijani Killed

Ali Larijani, one of Iran's most significant political figures, was killed in an airstrike. Larijani had served in numerous senior roles and was considered a pragmatic voice within the Iranian establishment. After Khamenei's death on Day 1, he had emerged as the de facto leader coordinating Iran's war effort and internal governance. His death dealt another devastating blow to Iran's leadership continuity.

A Reuters obituary described Larijani as Iran's "ultimate backroom powerbroker," noting his deep involvement in the JCPOA negotiations and his role as one of the few remaining Iranian leaders with diplomatic credibility among Western interlocutors. His killing further narrowed the path to any negotiated resolution.

Gholamreza Soleimani Killed

Gholamreza Soleimani, the head of the Basij militia — Iran's internal repression force responsible for crushing domestic dissent — was also confirmed killed. The Basij had played a central role in the brutal crackdown on protesters in December 2025 and January 2026 that killed at least 30,000 people. His death was met with celebration by many Iranian dissidents.

Israel Invades Lebanon

Israel launched a limited ground invasion of Lebanon, with reports suggesting a broader ground offensive was likely to follow. The incursion came after two weeks of Israeli air strikes on over 500 Hezbollah targets and represented a significant escalation — transforming the Lebanon front from an air war into a ground conflict.

The invasion followed weeks of sweeping evacuation orders across southern Lebanon and intensifying clashes between Hezbollah fighters and Israeli troops. The IRGC had rebooted Hezbollah's capabilities in the months before the war, making the militia a more formidable force than expected.

Political Developments

Iran's Leadership Crisis Deepens

With Larijani's death, Iran had now lost:

  • Ali Khamenei — Supreme Leader killed on Day 1
  • Ali Larijani — De facto leader post-Khamenei (Day 18)
  • Dozens of senior military and intelligence officials — Throughout the campaign

While Mojtaba Khamenei had been named the new Supreme Leader on Day 10, his authority was untested and his physical condition was reportedly uncertain. Larijani's death left a void in both military coordination and potential diplomatic engagement.

Live Coverage

The New York Times provided live updates throughout the day as the twin developments of Larijani's assassination and the Lebanon ground invasion reshaped the conflict's trajectory.

Economic Impact

  • Lebanon — The ground invasion threatened to further devastate an economy already crippled by years of crisis, with over 800,000 newly displaced
  • Iran — The continued elimination of senior leadership added uncertainty to Iran's ability to manage its wartime economy
  • Regional markets — The opening of a ground front in Lebanon added another layer of instability

International Reaction

  • Lebanon — President Aoun's earlier calls for a truce went unheeded as Israeli ground forces crossed the border
  • France — Previously expressed support for Lebanon; the ground invasion was expected to intensify European criticism
  • Iranian diaspora — Many celebrated the death of Soleimani, who oversaw the Basij's role in killing protesters
  • Diplomatic community — Larijani's death was seen as particularly damaging to any future negotiation prospects

What to Watch

  • Scope and objectives of Israel's ground operations in Lebanon
  • Whether Israel's ground invasion will expand beyond its initial "limited" scope
  • Iran's ability to maintain coherent command and control after Larijani's death
  • Hezbollah's response to the ground invasion — will it trigger full mobilization?
  • International reaction to the Lebanon ground offensive
