The US-Iran Conflict of 2026: A Comprehensive Overview

This story synthesizes multiple accounts covering the US-Iran conflict, which began in late February 2026 with joint US-Israeli military strikes. The conflict has resulted in significant casualties, a leadership succession in Iran, widespread protests, diplomatic efforts including a ceasefire, and shifts in Iran's internal power structure.

Conflict Timeline and Military Operations

Initiation of Operations

On February 28, 2026, joint US-Israeli military operations commenced in Iran. US President Donald Trump announced the start of "major combat operations." The Pentagon reported that US forces had hit over 5,000 targets by March 8. A US defense official described the campaign as "Operation Epic Fury." Israeli officials reported dropping over 5,000 bombs.

Civilian Casualties: The Minab School Strike

On February 28, 2026, a strike occurred at the Shajareh Tayyebeh girls' elementary school in Minab, Hormozgan province, southern Iran. Iranian state media reported casualties ranging from 148 to 168 killed, predominantly children aged 7-12, and at least 95 injured. These figures have not been independently verified.

Multiple lines of evidence indicate the strike was likely a US Tomahawk cruise missile.

Video evidence: A video geolocated by the Associated Press and analyzed by Bellingcat showed a missile impacting a compound near the school. Bellingcat identified the munition as a Tomahawk cruise missile, a weapon used by the US Navy in this conflict. US Central Command released a photo of the USS Spruance firing a Tomahawk on February 28.

Debris analysis: Photographs of fragments from the site, analyzed by CNN and experts, showed components consistent with a US-made Tomahawk cruise missile, including a satellite data link antenna from Ball Aerospace and an actuator motor from Ohio-based Globe Motors, both companies with US defense contracts.

Satellite imagery: Satellite images showed at least seven buildings near the school were impacted. The school was adjacent to a military complex containing an Islamic Revolutionary Guard Corps (IRGC) naval base. Historical satellite imagery indicates a wall was erected separating the school from the military complex between 2013 and 2016, and the school featured murals and separate access from the public street. A clinic on the compound was opened in 2025 by an IRGC official.

Official investigations: A preliminary US military investigation, reported by The New York Times and CNN, determined the strike was likely a "targeting error" resulting from outdated intelligence. A US official familiar with internal deliberations stated the strike was likely American. The Pentagon confirmed it is investigating the incident. A formal investigation was launched by the US military.

Disputed claims: President Trump initially stated the strike was "done by Iran," later stating "I don't know about it." He also claimed Iran possesses Tomahawk missiles, a claim disputed by arms experts who state Iran does not have this weapon. Defense Secretary Pete Hegseth stated the US is investigating and does not target civilians. Israel denied involvement.

International reactions included condemnation from UNESCO and Nobel Peace Prize laureate Malala Yousafzai. The UN human rights office called for an investigation. Over 120 Democratic members of Congress requested details from the Pentagon on civilian harm mitigation and the role of AI in target selection.

Under international humanitarian law, deliberately attacking a school, hospital, or other civilian structure can constitute a war crime.

Reported Attacks on Nuclear Facilities and Civilian Infrastructure

Iran's ambassador to the IAEA alleged strikes on the Natanz enrichment facility. IAEA Director-General Rafael Grossi stated the agency has "no indication" nuclear facilities were hit. Grossi confirmed no elevation of radiation levels had been detected in bordering countries.

Strikes impacted oil depots in and around Tehran, resulting in thick black smoke and warnings about toxic acid rain from authorities. Six fatalities and 20 injuries were reported at one depot. Damage was reported at Golestan Palace, a UNESCO World Heritage site. Strikes near Azadi Square closed a highway, and a police station near Enghelab Square was also struck.

Post-Conflict Ceasefire

A two-week ceasefire was brokered by Pakistan. Under the terms, the US and Israel are to halt attacks, and Iran is to reopen the Strait of Hormuz. US Defense Secretary Pete Hegseth declared a "historic and overwhelming victory." President Trump described a 10-point Iranian proposal as a "workable" basis for further talks. Iran submitted a 14-point counter-proposal, which President Trump described as "TOTALLY UNACCEPTABLE."

Iran Leadership Succession

Death of Ayatollah Ali Khamenei

Iranian state media confirmed the death of Supreme Leader Ayatollah Ali Khamenei in the February 28 strikes. Reports indicate he was killed by an Israeli missile strike on his compound in Tehran. His death marked the end of nearly 37 years in power. A preliminary funeral ceremony was postponed.

Succession and Election of Mojtaba Khamenei

Mojtaba Khamenei, son of the late supreme leader, was appointed as Iran's third supreme leader by the Assembly of Experts, a body of 88 senior clerics. The decision was reportedly made amidst conflict and reported pressure from the IRGC.

Background:

• Born 1969 in Mashhad. Served in the Revolutionary Guard during the Iran-Iraq war.
• A mid-ranking cleric who held no formal government position but operated as a key intermediary between his father and the IRGC.
• Sanctioned by the US Treasury in 2019 for alleged actions to advance his father's objectives.
• Reported to have accumulated substantial overseas fortune managed through intermediaries.

Status: His condition and whereabouts have been subjects of conflicting reports. Iran's ambassador to Cyprus stated he was injured in the same airstrike that killed his father. Other reports suggest he suffered injuries including a fractured foot. He has not made a public appearance since his appointment. State media used archival footage and an AI-generated profile photo. A leaked audio report by Iran International indicated he survived the strike on his father's compound. US and Israeli intelligence assess he is alive but does not exercise substantial control, with the IRGC reportedly holding significant power. The US announced a $10 million reward for information leading to his location.

Domestic Unrest and Crackdown

Protests and Casualties

Nationwide protests began on December 28, 2025, triggered by the collapse of the Iranian rial and economic hardship. The protests escalated into calls for regime change. The largest demonstrations occurred on January 8, 2026, following a call from exiled Crown Prince Reza Pahlavi.

Reports of casualties from the government crackdown vary significantly:

• Iran's government reported 3,117 deaths on January 21, 2026.
• The US-based Human Rights Activists News Agency (HRANA) updated its toll multiple times, reporting over 7,000 confirmed deaths and investigating over 11,000 additional cases.
• TIME magazine reported figures of 30,000-33,000 deaths from two senior Health Ministry officials, which have not been independently verified.
• Iran International reported over 36,000 deaths based on medical data.

Over 50,000 people have been reported detained. The government implemented a near-total internet and communications blackout on January 8. An eyewitness account from an individual involved with state repression described coordinated military-style operations involving recruitment of civilians and deployment of snipers.

International Responses to Crackdown

US President Donald Trump warned of "very strong action" if executions proceeded, and later stated he received assurances from "very important sources" that executions would not take place. The US Treasury imposed sanctions on 18 Iranian officials. The European Union imposed sanctions on 15 officials and six organizations. Gulf states, including Saudi Arabia, Qatar, and Oman, engaged in diplomatic efforts to discourage US military action.

Post-Conflict: Iran's Power Structure

Reports indicate the IRGC has blocked presidential appointments, established a security cordon around Supreme Leader Mojtaba Khamenei, and assumed control over key state functions. A "military council" of senior IRGC officers now manages access to the leader and key decisions. Reports emerged of Iranian forces deploying personnel and weapons at civilian sites, including 34 schools, across 17 provinces.

Diplomatic and Nuclear Negotiations (Pre-Conflict)

The US and Iran held several rounds of indirect nuclear talks in Geneva, mediated by Oman, prior to the February 28 conflict. Key points of disagreement included:

• US demand for a complete halt to uranium enrichment by Iran.
• Iran's insistence on its right to peaceful enrichment and seeking sanctions relief.
• US desire to expand talks to include Iran's missile program and support for regional armed groups, which Iran rejected.
• IAEA reported being unable to verify Iran's uranium stockpile due to restricted access.

Iran's Deputy Foreign Minister stated in March that Iran is not ready for direct talks, calling US demands "maximalist."

Regional and International Reactions

• Saudi Arabia, UAE, Bahrain: Stated they would not permit their airspace for attacks on Iran, urging restraint.
• Spain: Denied use of its military bases for attacks on Iran.
• European Union: Expressed concerns and considered additional sanctions.
• China and Russia: Provided diplomatic and economic support to Iran.
• Australia: Suspended embassy operations after expelling Iran's ambassador over alleged attacks on Australian Jewish community.

Reza Pahlavi's Role

Reza Pahlavi, the exiled son of Iran's last shah, positioned himself as a leader of the opposition, advocating for a secular democracy and seeking international support for regime change. He called for mass demonstrations and offered to lead a transitional government. He met with US envoy Steve Witkoff.

Economic and Energy Market Impact

• Oil prices: Brent crude rose to over $100 per barrel during the conflict, before settling around $70 after the ceasefire.
• Strait of Hormuz: Iran temporarily closed the strait for live-fire drills and later reopened it as part of the ceasefire agreement. The strait is a critical waterway for 20% of global oil supply.
• Western Australia: Experienced significant fuel price increases, impacting mining, agriculture, and tourism sectors.
