The killing of Iran’s supreme leader and other top Iranian officials came after close intelligence sharing between the United States and Israel, according to people familiar with the operation.
TEHRAN — Shortly before the United States and Israel launched the most ambitious military assault on Iran in decades, the C.I.A. zeroed in on the location of the most consequential target in the Islamic Republic: Ayatollah Ali Khamenei.
The agency had been tracking the 86-year-old supreme leader for months, meticulously mapping his movements and communication patterns. According to officials familiar with the operation, the breakthrough came when intelligence indicated that a high-level emergency meeting of Iran’s national security echelon would take place on Saturday morning at a leadership compound in the heart of Tehran.
Most critically, the C.I.A. passed “high-fidelity” intelligence to Israel confirming that Mr. Khamenei himself would be present.
The information prompted a sudden shift in military planning. The United States and Israel, which had originally intended to launch a broader strike under the cover of darkness, moved the timeline up to Saturday morning to catch the leadership gathered in one place. The result was a decapitation strike that has effectively dismantled the top tier of Iran’s political and military command, plunging the region into a volatile new era.
A Window of Opportunity
The swift removal of the supreme leader reflected a level of intelligence penetration that would have been unthinkable only years ago. It was the culmination of deep coordination between Washington and Jerusalem, fueled by intelligence gains made during the 12-day air war in June 2025.
On Saturday, Israel executed the strike using long-range, highly accurate munitions. While the U.S. provided the critical locating data and tactical support, Israeli fighter jets carried out the kinetic portion of the mission, which the Pentagon has referred to as Operation Epic Fury.
By 9:40 a.m. in Tehran, the missiles struck the compound. At the time, senior national security officials were gathered in one building; Mr. Khamenei was in a nearby structure within the same perimeter. Satellite imagery released on Sunday showed black smoke billowing from the site and heavy damage to the supreme leader’s personal quarters.
The Fallen Leadership
While the Iranian state news agency, IRNA, initially remained silent, it confirmed on Sunday the deaths of several key figures. Beyond Ayatollah Khamenei, the toll includes the architects of Iran’s regional military strategy:
- Rear Adm. Ali Shamkhani: A long-time advisor to the supreme leader and head of the Military Council.
- Maj. Gen. Mohammad Pakpour: The commander in chief of the Islamic Revolutionary Guard Corps (IRGC) Ground Forces.
- Aziz Nasirzadeh: The Minister of Defense.
- Seyyed Majid Mousavi: The commander of the IRGC Aerospace Force.
The loss of these men leaves the IRGC—the most powerful institution in the country—without its veteran leadership at the very moment it faces a direct military threat from two of the world’s most advanced militaries.
A “Peace President” Goes to War
The strike marks a staggering gamble for President Donald Trump, who campaigned on a “peace through strength” platform and frequently criticized “forever wars.” In a video address posted on Truth Social, Mr. Trump defended the decision, describing it as a necessary step to prevent a nuclear-armed Iran and to “take back” the region from what he called a “terrorist regime.”
“Khamenei is dead,” Mr. Trump stated. “There was not a thing he, or the other leaders killed with him, could do. This is justice for the people of Iran.”
The White House has framed the strikes as a preemptive measure to dismantle Iran’s ballistic missile array and air defense systems. However, critics in the international community, including envoys from Russia and China, have condemned the move as an illegal act of regime change that occurred while indirect nuclear negotiations were still underway in Oman.
The Regional Firestorm
The fallout was instantaneous. Within hours of the strike, Iran launched a massive retaliatory wave of drones and ballistic missiles. The targets were not limited to Israel; missiles struck near U.S. bases and civilian infrastructure across the Persian Gulf, including targets in Dubai, Doha, and Manama.
- Strait of Hormuz: Shipping firms, including major Japanese carriers, have halted operations as the vital waterway becomes a primary battleground.
- Global Markets: Oil prices saw an immediate spike as the UAE and other Gulf states adjusted fuel prices in anticipation of a prolonged conflict.
- Civilian Impact: While the U.S. reported no military casualties in the initial retaliation, civilian aviation has been paralyzed, with Air India and other major carriers cancelling dozens of flights to the region.
The Vacuum in Tehran
In Tehran, the mood is a chaotic blend of mourning and uncertainty. The government has declared 40 days of national mourning and a seven-day public holiday. While state television broadcasted images of grief-stricken crowds, other reports suggested pockets of celebration among Iranians who have spent years protesting the clerical establishment’s grip on power.
The 88-member Assembly of Experts is now tasked with choosing a successor to a leader who ruled for 36 years. However, with the IRGC’s top commanders also killed in the strike, the C.I.A. has assessed that the transition may not be a peaceful one. Intelligence reports suggest that hardline elements of the Guard may attempt to seize direct control to prevent a total collapse of the system.
As the dust settles over the charred remains of the leadership compound in Tehran, the primary question for Washington and Jerusalem is no longer how to track the supreme leader—but what will rise from the vacuum his death has created.
Frequently Asked Questions: The Tehran Decapitation Strike
What exactly happened on March 1, 2026?
Following months of high-level surveillance, the C.I.A. and Israeli intelligence identified a rare gathering of Iran’s top leadership at a secure compound in central Tehran. In a coordinated daylight operation known as Operation Epic Fury (U.S.) and Operation Roaring Lion (Israel), Israeli fighter jets launched precision missiles at 9:40 a.m. local time, successfully killing Supreme Leader Ayatollah Ali Khamenei and several high-ranking military commanders.
Who were the key officials killed in the strike?
Beyond the Supreme Leader, Iranian state media (IRNA) has confirmed the deaths of:
- Rear Adm. Ali Shamkhani: Head of the Military Council and a primary strategist.
- Maj. Gen. Mohammad Pakpour: Commander in Chief of the IRGC Ground Forces.
- Aziz Nasirzadeh: Minister of Defense.
- Seyyed Majid Mousavi: IRGC Aerospace Force Commander.
- Ali Larijani: Secretary of the Supreme National Security Council (reports vary on his status).
How did the C.I.A. pinpoint the location?
The agency utilized “high-fidelity” intelligence, combining months of pattern-of-life analysis with a sudden breakthrough regarding a Saturday morning emergency meeting. This data allowed the U.S. and Israel to adjust their strike window from a nighttime mission to a morning “decapitation strike” to catch the targets while they were co-located.
What has been the immediate military response from Iran?
Iran launched a massive retaliatory wave of drones and ballistic missiles, dubbed Operation True Promise 4. Targets included:
- Major cities in Israel (Tel Aviv and Jerusalem).
- U.S. military bases across the Gulf (Qatar, Bahrain, and Kuwait).
- Civilian infrastructure, including airports in the UAE and Kuwait.
- The Strait of Hormuz, which Iran has effectively declared a closed military zone.
How is the international community reacting?
- United States: President Trump has called the strike “justice” and a chance for the Iranian people to “take back their country.”
- United Nations: Secretary-General António Guterres called for an immediate cessation of hostilities, while Russia and China condemned the strikes as a violation of sovereignty that “stabbed diplomacy in the back” during active nuclear negotiations.
- Regional Allies: Gulf states like the UAE and Bahrain are on high alert, facing direct missile threats and significant disruptions to civil aviation.
Who will succeed Ayatollah Khamenei?
The Assembly of Experts is constitutionally mandated to select a new leader. However, with the IRGC leadership also decimated, there are significant fears of a power vacuum. C.I.A. assessments suggest hardline elements of the remaining IRGC may attempt a military takeover to maintain order, while the U.S. has openly called for a popular uprising.
