A multi-front conflict involving the United States, Israel, and Iran has rapidly escalated across the Middle East since its initiation on February 28, 2026. The period has been marked by extensive military operations, significant casualties across multiple nations, widespread economic disruption, particularly concerning global energy markets, and complex, often conflicting, diplomatic efforts.
Initiation of Conflict and Stated Objectives
On February 28, 2026, the United States and Israel launched military strikes against targets in Iran.
- U.S. President Donald Trump announced the commencement of "major combat operations," termed Operation Epic Fury, stating the objective was to eliminate threats from the Iranian regime and defend Americans.
- Israeli Prime Minister Benjamin Netanyahu articulated objectives to remove an "existential threat" and create conditions for the Iranian people to "take their destiny into their own hands."
- Israeli Defense Minister Israel Katz confirmed a "pre-emptive attack."
- U.S. objectives also included destroying Iran's missile and nuclear programs, incapacitating its navy, and ending its ability to arm proxy forces.
- The U.S. administration cited a "feeling" of an impending Iranian attack, later clarified as "based on fact." However, some U.S. intelligence officials privately indicated no intelligence corroborated an imminent preemptive threat. Israel reportedly tracked senior Iranian leaders and used this intelligence to influence the timing of strikes.
- This conflict followed a 12-day U.S.-Israeli air conflict with Iran in June 2025, which reportedly weakened Iran's air defenses and nuclear program.
Key Events in Early Days of Conflict
February 28:
- Explosions were reported in Tehran, near the offices of Supreme Leader Ayatollah Ali Khamenei.
- Reports indicated a girls' school in Minab, southern Iran, was hit, with numerous child fatalities. Iran attributed this to U.S.-Israeli strikes. A preliminary U.S. military investigation later suggested potential U.S. responsibility, possibly due to outdated targeting information.
- Iran launched retaliatory missile and drone strikes targeting Israel and several Gulf states, including Bahrain, Kuwait, Qatar, the United Arab Emirates (UAE), Saudi Arabia, and Jordan.
- The Strait of Hormuz, a critical global oil transit route, became effectively closed or disrupted by Iran.
March 1:
- Some Iranian missiles reportedly penetrated Israeli defense systems, causing damage in Tel Aviv.
- Iran's state media confirmed the death of Supreme Leader Ayatollah Ali Khamenei, announcing 40 days of mourning. Other senior Iranian officials, including the Defense Minister, Head of Armed Forces, and Head of the Revolutionary Guards, were also reportedly killed in the initial strikes.
- An Iranian attack on Beit Shemesh, Israel, reportedly killed nine people.
- Three U.S. service members were killed in a drone strike at a tactical operations center in Port Shuaiba, Kuwait, with many more injured. Iranian intelligence was suspected of tracking U.S. troop movements prior to the attack.
- A U.S. diplomatic facility in Iraq was hit.
March 2:
- Hezbollah, a Lebanon-based militant group, launched rockets into northern Israel, leading to retaliatory Israeli airstrikes in Lebanon.
- Iran's U.N. ambassador reported over 1,300 deaths in Iran from U.S.-Israeli strikes since the conflict began.
March 6:
- An Israeli tank reportedly struck a United Nations Interim Force in Lebanon (UNIFIL) position, injuring three peacekeepers.
Leadership and Political Developments
Iranian Leadership Succession
- Following the death of Ayatollah Ali Khamenei, his 56-year-old son, Mojtaba Khamenei, was appointed as Iran's new Supreme Leader by the Assembly of Experts on March 8.
- Mojtaba Khamenei reportedly sustained injuries, potentially disfiguring, and has not appeared publicly since his appointment, with initial statements delivered via state television.
- His appointment, given his ties to the Revolutionary Guard, was seen as a signal of continued hardline policies. Israel threatened to target any successor deemed a threat.
- On March 20, Iranian Intelligence Minister Esmail Khatib was reportedly killed in an Israeli airstrike, following the earlier reported killings of top security official Ali Larijani and Basij force head Gholam Reza Soleimani on March 18. Iran did not immediately confirm Khatib's death.
- On March 25, Mohammad Bagher Zolghadr, a retired IRGC commander, was appointed secretary of Iran's Supreme National Security Council, replacing Ali Larijani.
Internal Dynamics in Iran
- Reports described widespread fear, increased checkpoints, internet blackouts, and security forces searching phones. Iran's police chief warned against street demonstrations.
Trump's Shifting Stance
- President Trump issued varied statements on the conflict's objectives and duration, at times calling for "unconditional surrender," claiming "victory," or seeking a negotiated end.
- He expressed disappointment over Mojtaba Khamenei's appointment and reportedly suggested a potential assassination.
Iranian Presidential Statements
- Iranian President Masoud Pezeshkian initially apologized for attacks on neighboring countries, attributing them to "miscommunication in the ranks" after the supreme leader's death.
- However, he later reversed this stance, affirming Iran's strong response to pressure and rejection of unconditional surrender.
Military Operations and Targets
U.S. and Israeli Air Campaign in Iran
- The combined U.S.-Israeli force reportedly conducted over 15,000 strikes on targets across Iran. These included military command centers, missile and drone production sites, air defense systems, and nuclear facilities (e.g., Natanz, Shahid Khondab Heavy Water Complex, Ardakan yellowcake plant). Israel later claimed responsibility for strikes on Iran's nuclear facilities.
- U.S. forces utilized B-2 stealth bombers, Tomahawk missiles, F-35s, and F-15s. They claimed to have destroyed 92% of Iran's largest naval vessels and severely degraded air defenses and missile/drone launch rates.
- Strikes also targeted leadership compounds, security force checkpoints, and internal security service facilities. On March 14, U.S. forces destroyed military sites on Kharg Island, Iran's main oil export hub, while preserving oil infrastructure, with threats of reconsideration if shipping was disrupted.
Naval Engagements
- The U.S. military reported destroying 16 Iranian mine-laying vessels near the Strait of Hormuz.
- On March 18, a U.S. submarine reportedly sank an Iranian warship (IRIS Dena) in the Indian Ocean, resulting in a high number of Iranian sailor fatalities.
- U.S. forces also engaged Iranian boats in the Strait of Hormuz.
- Israel later reported killing Commodore Alireza Tangsiri, head of the Iranian Revolutionary Guard's navy, whom it accused of orchestrating operations blocking the Strait of Hormuz.
Iran's Retaliatory Strikes
- Iran launched ballistic missiles and drones at Israel, Gulf Arab states, and U.S. military bases in the region (Qatar, Bahrain, Kuwait, UAE, Saudi Arabia, Jordan, Iraq).
- Targets included military installations, oil/gas infrastructure (e.g., Qatar's Ras Laffan LNG facility, Kuwait's Mina Al-Ahmadi refinery, Saudi Arabia's Samref refinery), commercial shipping, and diplomatic facilities (e.g., U.S. Embassies in Baghdad and Riyadh).
- Iran used advanced missiles like Khorramshahr-4 and Qadr multiple-warhead missiles, and Shahed-136 drones. Iran claimed a missile strike on the Israeli town of Dimona, near its undeclared nuclear capabilities.
- On March 18, Iran responded to Israel's South Pars strike by attacking Qatar's Ras Laffan LNG facility and other Gulf energy sites.
- On March 22, Iran launched missile attacks on the southern Israeli communities of Dimona and Arad.
- On March 23, Iran reportedly launched missile attacks on Tel Aviv after the deaths of Ali Larijani and Gholamreza Soleimani.
Troop Deployments
- Thousands of U.S. Marines (USS Tripoli, USS Boxer groups) and Army paratroopers (82nd Airborne Division) were deployed to the Middle East, increasing the U.S. military presence to approximately 50,000-60,000 troops.
- These deployments were noted to enhance U.S. flexibility for potential future operations, including securing the Strait of Hormuz or limited ground operations in Iran.
Regional Impacts and Incidents
- Gulf States: Saudi Arabia, UAE, Qatar, Kuwait, and Bahrain reported intercepting hundreds of Iranian missiles and drones. Some attacks caused damage to airports, oil facilities, and residential areas, resulting in casualties. Formula One races in Bahrain and Saudi Arabia were canceled. Iran issued threats against UAE cities, accusing them of hosting U.S. forces, and urged evacuations.
- Lebanon: Israel intensified its bombing campaign against Iran-backed Hezbollah militants in Lebanon, conducting widespread airstrikes in Beirut and southern Lebanon. This led to significant civilian casualties and the displacement of over 1 million people. Israel also launched limited ground operations and expressed intent to establish a "security zone" up to the Litani River. Lebanon's government condemned Hezbollah's actions and issued arrest warrants.
- Yemen (Houthis): Iran-backed Houthi rebels entered the conflict on March 27, launching ballistic missiles and drones at Israel, raising concerns about disrupting shipping in the Bab el-Mandeb Strait, a critical choke point for global trade.
- Iraq: U.S. bases and the U.S. Embassy in Baghdad were repeatedly targeted by Iran-backed militias. On March 12, a U.S. KC-135 refueling aircraft crashed in western Iraq, killing six U.S. airmen. A French soldier was also killed in Erbil.
- Azerbaijan: Drones, reportedly from Iran, struck an airport terminal and near a school, injuring civilians.
- Syria: Israel conducted strikes in Syria, targeting military infrastructure and in response to attacks on the Druze minority.
- Maritime Incidents: Multiple commercial vessels were struck in the Strait of Hormuz and Gulf of Oman, causing fires and crew fatalities. Tankers were rerouted to avoid the strait. On March 13, two oil tankers were struck in Iraqi territorial waters near Basra.
Humanitarian Impact and Casualties
- Iran: Reported casualties ranged from over 1,200 to 2,300 deaths, including hundreds of children, and thousands injured. Up to 3.2 million people were displaced. Hospitals and civilian structures sustained extensive damage. The World Health Organization (WHO) warned of "black rain" from oil depot fires.

- Gulf States: Dozens of civilian fatalities and injuries.
- Iraq: 80+ security forces members killed, one French soldier killed.
- Occupied West Bank: Several fatalities.
- Humanitarian Aid: Global humanitarian supply chains were disrupted due to airspace closures and Strait of Hormuz restrictions. Iran later agreed to facilitate humanitarian and agricultural shipments through the strait.
Economic Impact and Strait of Hormuz
Oil Prices
- Brent crude oil prices surged by 20-65% (to $90-$120/barrel) due to supply disruptions and attacks on energy infrastructure. Gas prices in Europe more than doubled.
Strait of Hormuz
- The Strait of Hormuz was effectively closed to most commercial shipping, causing the "largest supply disruption in the history of the global oil market."
- Iran began charging tolls for safe passage for "non-hostile" vessels, coordinating with Iranian authorities. Vessels linked to the U.S., Israel, or allies were prohibited.
- U.S. President Trump issued ultimatums for Iran to reopen the strait or face attacks on energy plants, later extending deadlines due to "talks."
- International Energy Agency (IEA) members agreed to release 400 million barrels from emergency oil reserves, with the U.S. releasing 172 million barrels.
Global Supply Chains
- Disruptions affected fuel, fertilizer, pharmaceuticals, and semiconductors. Cargo flights were grounded, and shipping firms rerouted vessels.
Stock Markets
- Global stock markets experienced significant declines.
Sanctions
- The U.S. temporarily lifted sanctions on some Iranian oil (140 million barrels already loaded on ships) and Russian oil (for cargoes already at sea) to stabilize markets.
Diplomatic Efforts and International Reactions
U.S.-Iran Negotiations
- Conflicting reports emerged regarding U.S.-Iran talks. Trump claimed "productive" discussions and "major points of agreement," while Iran consistently denied direct negotiations, calling U.S. claims "fake news" and "deceptive."
- The U.S. proposed a 15-point ceasefire plan (via Pakistan) including sanctions relief, nuclear limits, missile curbs, and reopening the Strait.
- Iran rejected the U.S. plan and presented a 5-point counter-proposal including compensation, guarantees against future attacks, end of hostilities, and recognition of its sovereignty over the Strait of Hormuz.
- Pakistan, Egypt, Turkey, and Oman engaged in mediation efforts.
International Stance on Strait of Hormuz
- Trump urged NATO and other allies (China, France, Japan, South Korea, UK, Australia) to deploy warships to secure the Strait.
- Most European nations, Canada, and Australia declined direct military involvement, citing a lack of consultation, no U.N./EU/NATO mandate, and a desire to avoid being drawn into a wider conflict.
- Trump criticized NATO, linking allied participation to the alliance's future.
U.N. Involvement
- The U.N. Security Council condemned Iran's attacks on Gulf neighbors but the resolution was criticized by China and Russia for not mentioning initial U.S.-Israeli strikes. U.N. Secretary-General António Guterres called for de-escalation.
Russia and China
- Russia reportedly provided intelligence to Iran but did not directly intervene militarily, while China called for dialogue and dispatched an envoy for mediation.
European Concerns
- European leaders prioritized the energy crisis and potential refugee flows, advocating for diplomatic solutions and increased EU sanctions on Iran.
Australian Involvement
- Australia supported U.S.-Israeli actions but affirmed no participation in offensive actions. It deployed air-to-air missile systems and a reconnaissance plane to defend Gulf states.
Outlook and Future Threats
- Conflict Duration: The conflict entered its second month, exceeding initial U.S. projections of 4-6 weeks. Israeli military officials estimated several more weeks of operations were needed.
- Ground Invasion Speculation: The U.S. Pentagon was reportedly preparing for potential limited ground operations in Iran (e.g., Kharg Island, coastal sites), though no presidential approval was given. Iran threatened to mine the Persian Gulf if an invasion occurred.
- Regional Threats: Iran threatened to target global recreational/tourist sites for adversaries. It also warned against any facility in the Middle East with U.S. ties if its own oil infrastructure was attacked.
- Nuclear Concerns: Despite claims of Iranian nuclear program degradation, international monitors estimated Iran still possessed nearly bomb-grade uranium.
- Leadership Stability: Despite the death of the Supreme Leader, the Iranian regime's command structure remained intact, and replacements were swiftly appointed.
End of March Developments
