Operation Roaring Lion: Inside the US-Israeli Strike That Killed Iran's Supreme Leader and Plunged the Middle East Into Crisis

In the predawn hours of February 28, 2026, a coordinated barrage of American and Israeli missiles tore through Tehran, striking the compound of Ayatollah Ali Khamenei, the man who had ruled the Islamic Republic of Iran for 37 years. By morning, Iran's state media confirmed what four Israeli security officials had already briefed reporters on: the Supreme Leader was dead [1][7].

The assassination of Khamenei — the most consequential targeted killing since the United States struck Iranian General Qasem Soleimani in 2020 — has ignited a regional conflagration that now stretches from the streets of Tehran to the shipping lanes of the Strait of Hormuz. What the Pentagon calls Operation Epic Fury and Israel calls Operation Roaring Lion is not merely a military campaign. It is, by the admission of its architects, an attempt at regime change in one of the world's most strategically consequential nations [5][8].

The Strike: Scale and Scope

The operation that killed Khamenei was staggering in its scale. U.S. Central Command initiated Operation Epic Fury at 01:15 ET on February 28, describing it as a joint effort to "dismantle the Iranian regime's security apparatus" [5]. Simultaneously, Israel launched Operation Roaring Lion — what Israeli officials called the largest operational strike sortie in Israeli Air Force history, involving approximately 200 warplanes targeting roughly 500 objectives [5][10].

The targets were not limited to Khamenei's compound. Strikes hit Islamic Revolutionary Guard Corps command and control facilities, air defense systems, ballistic missile infrastructure, military airfields, government ministries, and — critically — nuclear sites, including the Natanz enrichment facility [5][11]. President Donald Trump declared that the operation's objective was threefold: destroy Iran's missile and military capabilities, prevent Iran from obtaining nuclear weapons, and topple the regime [8][11].

Trump called Khamenei "one of the most evil people in history" in a Truth Social post announcing his death. In a video address, Trump told Iranians to "take over your government" when the U.S. was finished. "It will be yours to take," he said [8][11].

The Human Cost

The military objectives, however, have come at a severe humanitarian price. According to the Iranian Red Crescent Society, at least 555 people had been killed across Iran by the operation's third day, with the Human Rights Activists News Agency documenting casualties across 18 provinces in at least 59 separate incidents [12][13].

Among the most devastating individual strikes was an attack on an elementary girls' school in the city of Minab in southeastern Iran, which Iranian state media reported killed approximately 148 young children [13]. A major hospital in Tehran was also struck. In the capital, more than 20 people were killed in an attack on Niloofar Square, and U.S. and Israeli forces dropped six missiles on different parts of the city of Sanandaj, including densely populated neighborhoods [13].

The carnage has not been confined to Iran. On March 1, an Iranian retaliatory missile struck a synagogue and residential buildings in Beit Shemesh, Israel, killing nine people and injuring 49 others [13].

Iran's Retaliation: A Multi-Front Response

Tehran's response was swift and expansive. Within hours of the initial strikes, Iranian forces launched missiles against targets in Tel Aviv and Haifa, as well as at U.S. military installations across the Persian Gulf region [3][4]. Iran's retaliatory fire reached into Bahrain, Kuwait, Jordan, Qatar, Saudi Arabia, and the United Arab Emirates — every nation hosting significant American military assets [4][6].

The damage was tangible. An Iranian strike on Mina Salman port in Bahrain caused a fire and killed at least one worker. A refining facility at Aramco's Ras Tanura complex in Saudi Arabia sustained damage. Explosions were reported in Dubai, Abu Dhabi, and Doha [4].

The conflict has also drawn in Iran's regional proxies. Hezbollah fired rockets into northern Israel on March 2 for the first time since the November 2024 ceasefire, and Yemen's Houthi movement announced it would resume missile and drone attacks on U.S. and Israeli-flagged ships in the Red Sea [4][6].

Trump responded by vowing to "avenge" the deaths of U.S. service members and stated that combat operations would continue, predicting the war would last four to five weeks [6][12].

The Road to War: Protests, Repression, and Diplomatic Collapse

The strikes did not materialize in a vacuum. Understanding how the world arrived at this moment requires examining months of cascading crises.

Beginning in late December 2025, Iran was consumed by the largest nationwide protests since the 1979 revolution [14][15]. The catalyst was economic: the Iranian rial had lost more than 40 percent of its value since Israel's 12-day conflict with Iran the previous June. Water and electricity cuts, rising prices, and disillusionment with President Masoud Pezeshkian — elected in 2024 on promises of good governance — drove protesters into the streets of more than 100 cities [14][15].

The chants were unambiguous: "Death to the Dictator," referring directly to Khamenei [14]. The Iranian government responded with extraordinary violence. By late January, reports from Time, The Guardian, and Iran International estimated that between 30,000 and 36,500 protesters had been killed during the deadliest crackdowns on January 8-9, 2026 alone. The U.S.-based HRANA confirmed at least 7,015 deaths, of which 6,508 were protesters [15].

On January 13, Trump voiced support for the protesters. On January 23, he announced a U.S. "armada" was heading to the Middle East, including the aircraft carriers USS Abraham Lincoln and USS Gerald R. Ford [15].

Yet even as military preparations accelerated, diplomacy was still in motion. Iranian Foreign Minister Abbas Araghchi told NBC News that a team of Iranian negotiators had been in talks with U.S. special envoys Steve Witkoff and Jared Kushner in Geneva with the aim of averting a military assault. "A deal was at our reach," Araghchi said, claiming Iran was prepared to address serious questions related to its nuclear program [16]. The strikes came while those talks were reportedly still ongoing — a point that has drawn sharp criticism from analysts and diplomats worldwide.

A Leadership Vacuum: Who Rules Iran Now?

Khamenei's death has left Iran without its most powerful figure for the first time in nearly four decades. Under Article 111 of the Iranian constitution, a three-person interim council now governs the country: President Masoud Pezeshkian, judiciary chief Gholamhossein Mohseni Ejei, and senior cleric Alireza Arafi [17][18].

The Assembly of Experts — the 88-member body of senior clerics constitutionally tasked with selecting a new Supreme Leader — faces an unprecedented challenge. Khamenei had reportedly nominated three potential successors: Mohseni Ejei, Asghar Hijazi, and Hassan Khomeini (grandson of the Islamic Republic's founder). Other candidates discussed include Khamenei's own son Mojtaba, and figures like Ali Larijani and Sadiq Larijani [17][18].

But with U.S. and Israeli strikes ongoing, the Assembly may not be able to convene safely, prolonging the power vacuum at a moment when the country is under direct military assault [17]. Analysts at the Council on Foreign Relations and the Washington Institute have warned that this interregnum could lead to factional infighting within the regime or, conversely, could consolidate hardliner control as the IRGC asserts authority during wartime [11][19].

Global Reaction: Condemnation and Alarm

The international response has been swift and largely critical.

UN Secretary-General António Guterres said the strikes violated international law, including the UN Charter. "We are witnessing a grave threat to international peace and security," he declared at an emergency Security Council session on February 28. "Military action carries the risk of igniting a chain of events that no one can control" [9][20].

Russia's President Vladimir Putin called Khamenei's killing a "cynical murder" that violated "all standards of human morality and international law." China's Foreign Ministry issued a statement firmly opposing and strongly condemning the attacks as "a grave violation of Iran's sovereignty and security" that "tramples on the purposes and principles of the UN Charter," calling for an immediate halt to military operations [9][20].

The Gulf Cooperation Council — comprising Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the UAE — held an emergency video conference as its member states suddenly found themselves caught in the crossfire of Iranian retaliatory strikes against U.S. bases on their soil [9].

Economic Shockwaves: Oil Markets in Turmoil

The conflict has sent tremors through global energy markets. U.S. crude oil surged more than 7 percent, while Brent crude, the international benchmark, jumped 9 percent — the largest single-session gain in four years [21][22].

The central concern is the Strait of Hormuz, through which approximately 20 million barrels of oil — roughly one-fifth of daily global production — flow each day. At least four vessels have been hit in Gulf waters since the conflict began, and shipping companies have halted tanker traffic through the strait [21][22].

American consumers will feel the impact directly. Analysts at GasBuddy estimated that the crude oil spike would push U.S. gasoline prices up by 10 to 30 cents on average within days, with some stations seeing increases as high as 85 cents [22]. If the conflict persists for several weeks, some analysts project crude could reach $100 per barrel [22].

Investors have fled to safe-haven assets: the U.S. Dollar Index rose 1 percent, and gold futures jumped more than $100, or 2 percent [22].

What Comes Next

As of March 3, the strikes continue. Israel's Prime Minister Benjamin Netanyahu has said the goal is to "remove the existential threat posed by the terrorist regime in Iran" and to "create the conditions for the brave Iranian people to take their destiny into their own hands" [8][16].

But regime change from the air has a troubled historical track record. Analysts at The Conversation and Chatham House have warned that Iran's regime was built to survive external shocks and that a prolonged war is now likely [19][23]. Inside Iran, public reaction has been mixed — some citizens celebrated Khamenei's death in the streets of Isfahan, Karaj, Kermanshah, and other cities, while President Pezeshkian condemned it as "a great crime" [2][7].

The coming weeks will determine whether this operation achieves the swift conclusion its architects envision or whether it becomes the opening chapter of a far longer and more destructive conflict — one that has already drawn in multiple nations, destabilized global energy markets, and raised questions about the boundaries of international law.

What is beyond dispute is that February 28, 2026, has become a hinge point in Middle Eastern history. The supreme leader who shaped Iran's trajectory for nearly four decades is dead. The system he built is shaken but still standing. And the reverberations of this moment are only beginning to be felt.
