Iran’s Supreme Leader Ali Khamenei Killed, Middle East Faces Uncertainty
Impact of Khamenei's Death on Iran and the Middle East
Details of the Attack and Immediate Aftermath
Feb 28 (Reuters) - Iran's Supreme Leader Ayatollah Ali Khamenei, who turned the country into a powerful anti-U.S. force and extended its military influence across the Middle East while crushing repeated domestic unrest, was killed in Israeli and U.S. strikes, a senior Israeli official told Reuters on Saturday.
There was no immediate Iranian confirmation of his fate.
The United States and Israel carried out military strikes on Iran on Saturday, targeting its top leaders and plunging the Middle East into a conflict that President Donald Trump said would end a security threat to the U.S. and give Iranians a chance to topple their rulers.
Khamenei’s Leadership and Legacy
Rise to Power and Authority
Khamenei, 86, became Iran's highest authority in 1989, following the death of the Islamic Republic's founder, Ayatollah Ruhollah Khomeini. As supreme leader, he held ultimate control over Iran's political, military and religious institutions, shaping domestic policy and guiding foreign relations.
Regional Influence and Tensions
Israel long saw him as a destabilizing force in the Middle East, citing his backing for Iran's network of militant allies, including Palestinian Hamas and Lebanon's Hezbollah. When Israel and Iran fought a 12-day air war in June 2025, Israeli Defence Minister Israel Katz threatened to assassinate him, saying the supreme leader "cannot continue to exist."
That war saw Israel launch a surprise strike that struck Iran's underground nuclear site, killed senior commanders and nuclear scientists, and wiped out much of the military leadership. Khamenei's killing deals another blow to a country already reeling from war and economic hardship.
Domestic Policies and Suppression of Dissent
Khamenei upheld the conservative vision of his predecessor, Khomeini, quashing the ambitions of elected presidents who sought more open policies at home and abroad. Under his rule, authorities crushed repeated protests and sidelined reformists pushing for less confrontation with the West.
Iran’s Regional Role and Shifting Alliances
Expansion of Influence
Iran became a powerful regional anti-U.S. force under Khamenei, extending its influence across the Middle East. He backed the 2015 nuclear deal brokered with world powers and pragmatist President Hassan Rouhani, which briefly eased Iran's isolation. But tensions spiked after U.S. President Donald Trump abandoned the accord in 2018 and reimposed sanctions.
Recent Setbacks for Iran and Its Allies
Since the Hamas-led attack on Israel on Oct. 7, 2023, Iran has seen its allies weakened. Hamas and Hezbollah suffered heavy blows from Israel, while Syrian President Bashar al-Assad, long propped up by Tehran, was toppled in December 2024.
Succession and Future Uncertainty
The Role of the Supreme Leader
The post of Supreme Leader was created after the 1979 revolution and enshrined in Iran's constitution, giving a top cleric ultimate authority over the president and parliament. The Assembly of Experts, an 88-member clerical body vetted by a hardline watchdog aligned with Khamenei, formally selects the leader.
