Coordinated U.S. and Israeli strikes over the weekend killed Iran’s Supreme Leader Ayatollah Ali Khamenei and dozens of senior Iranian figures, setting off intense Iranian retaliation and raising the danger of a wider regional war. Allies of the United States pledged assistance after Iran launched missile and drone attacks, and Lebanon’s Hezbollah said it struck Israel for the first time in over a year; Israel responded in kind.
Casualties and damage
Several countries reported fatalities. The U.S. military confirmed the deaths of three service members; Israel and Gulf states also reported casualties; Iran said hundreds were killed on its territory. The strikes hit a range of targets in Iran, including ballistic-missile sites, naval facilities, and, according to Iranian accounts, the Natanz uranium-enrichment complex—an assertion the U.S. and Israel have not publicly acknowledged. Tehran says it has not enriched uranium since June but has barred IAEA inspectors from sites struck by U.S. actions.
Iran’s political aftermath
Khamenei, 86, was killed when his compound was bombed. He left no officially designated successor. Tehran moved quickly to form a three-member leadership council to fill the immediate vacuum, and Foreign Minister Abbas Araghchi said a new supreme leader could be chosen within days. There have been scattered public celebrations inside Iran, but extensive internet restrictions have made it difficult to fully monitor public sentiment.
Iran’s military response
In retaliation, Iran launched hundreds of missiles and drones at Israel and at U.S. bases and installations across the region. Several people were killed in Israel and in neighboring Gulf countries, and hundreds of civilian flights were disrupted at major airports. Most incoming Iranian missiles and drones were intercepted, according to Israeli authorities, and civilians took shelter during the attacks.
United States: stance and risks
The strikes followed a U.S. military buildup that officials described as the largest in the region in decades. U.S. and Israeli forces had been tracking senior Iranian leaders for weeks. President Donald Trump said the “heavy and pinpoint bombing” would continue through the week or longer. Washington has indicated it remains open to dealing with Iran’s future leadership at some point, but members of Congress criticized the strikes for proceeding without explicit congressional authorization. U.S. bases and personnel in the region remain potential targets for further Iranian retaliation.
Israel: goals and operations
Israel, which has long viewed Iran as an existential threat, said its operations targeted senior leadership and elements of Iran’s nuclear and military infrastructure. Israeli jets and air defenses were heavily engaged, and the government announced sustained strike activity. Prime Minister Benjamin Netanyahu framed the operations as a security success amid ongoing international criticism of Israel’s conduct in Gaza. Israel also struck back in Lebanon after Hezbollah fired across the border. The risk of further attacks by Iranian proxies—such as Houthi rebels in Yemen—remains a key concern, particularly for shipping in the Red Sea.
Regional and global effects
The clashes have been more intense than last year’s confrontations between Israel and Iran, especially in scope: this round involved hundreds of Iranian launches that affected Gulf countries previously more insulated from direct strikes. Dubai’s main airport experienced disruptions as interceptor fire and defensive actions interfered with operations. Saudi Arabia reported intercepting attacks and summoned Iran’s ambassador; top diplomats from six Gulf states asserted their right to self-defense.
Markets reacted immediately: oil prices rose on fears of supply disruptions, especially given strikes near the Strait of Hormuz, a critical global oil chokepoint. In response to supply worries, eight OPEC+ members signaled plans to raise crude output. The International Atomic Energy Agency’s Board of Governors moved to consider the conflict’s implications and to seek updates on Iran’s nuclear activities and access for inspectors.
Context and precedent
The strikes came two days after U.S.-Iran talks aimed at constraining Tehran’s nuclear program. They echo last year’s pattern when an Israeli strike derailed negotiations and preceded a 12-day conflict that included U.S. strikes on Iranian nuclear sites. U.S. officials have accused Iran of rebuilding nuclear-capable infrastructure; Iran denies resuming enrichment and has restricted access to sites hit by the strikes.
What to watch next
– Additional military strikes and further retaliatory launches affecting Israel, U.S. forces, and Gulf states.
– The selection process and outcome for Iran’s next supreme leader and how the new leadership shapes Iran’s strategy.
– Domestic reaction inside Iran, including public protests or unrest and how the government manages information and internet access.
– Any diplomatic outreach from the United States or other international actors to Iran’s interim or successor leadership.
– Updates from the IAEA on Iran’s nuclear activities and inspector access.
– Oil-market volatility and broader economic consequences if fighting disrupts regional shipping lanes or production.
The situation remains fluid and volatile. Military activity, political decisions in Tehran, and international diplomatic responses over the coming days will determine whether the conflict escalates further or moves toward containment and de-escalation.
