Timeline: A recent history of the Israel-Iran conflict

The conflict between Iran and Israel has escalated yet again.
On June 13 morning, explosions rocked Tehran as Israel carried out a major attack intended to cripple the country's nuclear programme, Israeli officials said.
The strikes raised fears the long-simmering conflict between the two countries could escalate into a war involving the most powerful militaries in the Middle East.
Iran's rulers have pledged to destroy Israel and have long supported regional militias who share that goal. Israel views Iran as an existential threat and has vowed to prevent it from building a nuclear bomb.
In the past year, Israel and Iran have traded airstrikes as their once covert war has burst into the open.
Here is a recent history of the conflict:
2019
Strikes against Iran's allies
Israel carried out a series of attacks in Syria, Lebanon and Iraq to prevent Iran from equipping its allies with sophisticated weapons. Israel accused Iran of trying to establish an arms supply line through Iraq and northern Syria into Lebanon, where Iran had long backed the militant group Hezbollah.
Israel also attacked ships carrying Iranian oil and weapons through the eastern Mediterranean and Red seas.
2020
A remote-controlled assassination
In November, Israel killed Iran's top nuclear scientist, Mohsen Fakhrizadeh, with a remote-controlled machine gun.
2021
Skirmishes at sea
Iran and Israel increasingly began attacking each other at sea.
Israeli Prime Minister Benjamin Netanyahu accused Iran of being behind a February explosion on an Israeli-owned ship transporting vehicles sailing off the coast of Oman. Iran accused Israel in March of targeting an Iranian cargo ship about 50 miles off the coast of Israel. In April, an Iranian military vessel stationed in the Red Sea was damaged by an apparent Israeli mine attack. Such operations continued through the year.
2022
Assassination of an Iranian officer
In May, two assassins on motorcycles shot and killed Col. Sayad Khodayee, an officer in Iran's Revolutionary Guard. Israeli officials said he helped command a covert operations unit that conducted assassinations and abductions. Israel confirmed its role in the killing to the United States.
Two scientists die
Ayoub Entezari, an aeronautical engineer at a military research facility, and Kamran Aghamolaei, a geologist, died in May after developing symptoms of food poisoning. Iran said Israel poisoned them, but Israel declined to comment.
2023
The Oct 7 attacks
Palestinian militants led by Hamas, which is backed by Iran, attacked Israel, igniting a deadly war in the Gaza Strip. In solidarity with Hamas, other Iranian-backed militias in the region, including Hezbollah in Lebanon and the Houthis in Yemen, also attacked Israel.
Iran's supreme leader, Ayatollah Ali Khamenei, denied that Iran had any role in the Oct 7 attacks. But Hamas leaders spoke broadly about receiving support from regional allies, and documents show the group discussed its plans with Iran.
An airstrike in Syria
In December, Iran accused Israel of killing a high-level Iranian officer in a missile strike in Syria.
2024
A strike on Damascus, and several rounds of retaliation
In April, an Israeli airstrike on an Iranian Embassy building in Damascus killed three top Iranian commanders and four officers. Weeks later, Iran launched more than 300 drones and missiles at Israel, nearly all of which were shot down. Soon after, Israel attacked an anti-aircraft system in Iran that protects a nuclear facility.
An assassination in Tehran
In July, Ismail Haniyeh, Hamas' political leader, was assassinated in an explosion in a guesthouse in Tehran run by the Iran's Revolutionary Guard. Israel later confirmed that it was behind the killing.
A pager attack
In September, Iran's ambassador to Lebanon, Mojtaba Amini, lost an eye in a massive simultaneous pager attack targeting Hezbollah members. Similar attacks on electronic devices followed in subsequent days, killing dozens of people and injuring thousands. Israel later confirmed it conducted the attacks.
Hezbollah leader killed
In September, Israel killed Hezbollah's leader, Hassan Nasrallah, in airstrikes near Beirut, Lebanon's capital.
Iran fires at Israel
Iran in October fired about 180 ballistic missiles at Israel, in retaliation for Israel's assassinations of Nasrallah, Haniyeh and an Iranian commander. Most were intercepted.
Israel targets Iran's air defences
Israel launched airstrikes on Iran in late October that destroyed air-defence systems intended to protect critical infrastructure.
The airstrikes in April and October took out air-defense systems that Iran purchased from Russia, Iranian and Israeli officials said, including one in central Iran that is critical to the country's nuclear programme.
2025
Mr Netanyahu proposed to President Donald Trump a plan to strike Iranian nuclear sites, which Trump administration members debated for months. In April, Trump decided to pursue diplomacy instead.
Recently, Iran rejected the administration's demand to stop all uranium enrichment, but talks about its nuclear program are set to continue.
On June 12, Mr Trump said there was a risk that Israel could strike Iran, torpedoing the talks. 'I think it would blow it,' he said. 'Might help it actually, but it could also blow it.' NYTIMES

Iran weighs retaliation for U.S. strikes as Trump raises idea of regime change

MAXAR TECHNOLOGIES/Handout via REUTERS ISTANBUL/WASHINGTON/JERUSALEM - Iran and Israel traded air and missile strikes as the world braced on Monday for Tehran's response to the U.S. attack on its nuclear sites and U.S. President Donald Trump raised the idea of regime change in the Islamic republic. Iran vowed to defend itself on Sunday, a day after the U.S. joined Israel in the biggest Western military action against the country since its 1979 Islamic Revolution, despite calls for restraint and a return to diplomacy from around the world. Commercial satellite imagery indicated the U.S. attack on Saturday on Iran's subterranean Fordow nuclear plant severely damaged or destroyed the deeply buried site and the uranium-enriching centrifuges it housed, but the status of the site remained unconfirmed, experts said. In his latest social media comments on the U.S. strikes, Trump said "Monumental Damage was done to all Nuclear sites in Iran." "The biggest damage took place far below ground level. Bullseye!!!" he wrote on his Truth Social platform. Trump earlier called on Iran to forgo any retaliation and said the government "must now make peace" or "future attacks would be far greater and a lot easier." The U.S. launched 75 precision-guided munitions including bunker-buster bombs and more than two dozen Tomahawk missiles against three Iranian nuclear sites, the chairman of the Joint Chiefs of Staff, General Dan Caine, told reporters. The U.N. nuclear watchdog, the International Atomic Energy Agency, said no increases in off-site radiation levels had been reported after the U.S. strikes. Rafael Grossi, the agency's director general, told CNN that it was not yet possible to assess the damage done underground. A senior Iranian source told Reuters that most of the highly enriched uranium at Fordow had been moved elsewhere before the attack. Reuters could not immediately corroborate the claim. Tehran, which denies its nuclear programme is for anything other than peaceful purposes, sent a volley of missiles at Israel in the aftermath of the U.S. attack, wounding scores of people and destroying buildings in Tel Aviv. But it had not acted on its main threats of retaliation, to target U.S. bases or choke off the global oil shipments that pass through the Strait of Hormuz. Attempting to strangle the strait could send global oil prices skyrocketing, derail the world economy and invite conflict with the U.S. Navy's massive Fifth Fleet based in the Gulf. Oil prices jumped on Monday to their highest since January. Brent crude futures were up $1.52 or 1.97% to $78.53 a barrel as of 0503 GMT. U.S. West Texas Intermediate crude advanced $1.51 or 2.04% to $75.35. Iran's parliament has approved a move to close the strait, which Iran shares with Oman and the United Arab Emirates. Iran's Press TV said any such move would require approval from the Supreme National Security Council, a body led by an appointee of Iran's Supreme Leader Ayatollah Ali Khamenei. Caine said the U.S. military had increased protection of troops in the region, including in Iraq and Syria. The U.S. State Department issued a security alert for all U.S. citizens abroad, calling on them to "exercise increased caution." U.S. Secretary of State Marco Rubio called on China to encourage Iran to not shut down the strait, telling Fox News' "Sunday Morning Futures with Maria Bartiromo" show it would be a "terrible mistake." "It's economic suicide for them if they do it. And we retain options to deal with that, but other countries should be looking at that as well. It would hurt other countries' economies a lot worse than ours," he said. The Israeli military said on Monday about 20 jets had conducted a wave of strikes against military targets in western Iran and Tehran overnight. In Kermanshah, in western Iran, missile and radar infrastructure was targeted, and in Tehran a surface-to-air missile launcher was struck, it said. A missile launched from Iran in the early hours of Monday was intercepted by Israeli defences, it said. Air raid sirens blared overnight in Tel Aviv and other parts of central Israel. Iranian news agencies reported air defences were activated in central Tehran districts to counter "enemy targets", and that Israeli air strikes hit Parchin, the location of a military complex southeast of the capital. Israel's state broadcaster reported that an Israeli Hermes drone was shot down in Iranian territory, the fourth to be shot down in the area since the start of the campaign. REGIME CHANGE In a post to the Truth Social platform on Sunday, Trump raised the idea of regime change in Iran. "It's not politically correct to use the term, 'Regime Change,' but if the current Iranian Regime is unable to MAKE IRAN GREAT AGAIN, why wouldn't there be a Regime change??? MIGA!!!" he wrote. Trump's post came after officials in his administration, including U.S. Vice President JD Vance and Defense Secretary Pete Hegseth, stressed they were not working to overthrow Iran's government. Israeli officials, who began the hostilities with a surprise attack on Iran on June 13, have increasingly spoken of their ambition to topple the hardline Shi'ite Muslim clerical establishment. As Tehran weighed its options, Iranian Foreign Minister Abbas Araqchi is expected to hold talks with Russian President Vladimir Putin in Moscow on Monday. The Kremlin has a strategic partnership with Iran, but also close links with Israel. Speaking in Istanbul on Sunday, Araqchi said his country would consider all possible responses and there would be no return to diplomacy until it had retaliated. Russia's foreign ministry condemned the U.S. attacks which it said had undermined the Treaty on the Non-Proliferation of Nuclear Weapons, and warned of conflict spreading in the Middle East. The U.N. Security Council met on Sunday to discuss the U.S. strikes as Russia, China and Pakistan proposed the 15-member body adopt a resolution calling for an immediate and unconditional ceasefire in the Middle East. U.N. Secretary-General Antonio Guterres told the Security Council the U.S. bombings in Iran marked a perilous turn in the region and urged a return to negotiations over Iran's nuclear programme. Commercial airlines were weighing how long to suspend Middle East flights after the U.S. struck Iran. The Middle East route has become more important for flights between Europe and Asia but flight tracking website FlightRadar24 showed empty space on Sunday over Iran, Iraq, Syria and Israel.

Japanese ships transiting Strait of Hormuz to minimise time in Gulf
[TOKYO] Japan's Nippon Yusen and Mitsui O.S.K. Lines said on Monday they have instructed their vessels to minimise the time spent in the Gulf as they continue to transit the Strait of Hormuz following the US strikes on Iranian nuclear facilities. The shipping companies said they are closely monitoring the situation and sharing updates with ships operating in the region. 'We are instructing our vessels to shorten their time in the Persian Gulf whenever possible, depending on their schedules,' a Nippon Yusen spokesperson said. 'We will make decisions on each vessel's passage through the Strait of Hormuz on a flexible basis,' he added. MOL's safety operation supporting centre in Tokyo has stepped up 24-hour surveillance, a company spokesperson said. 'We are advising vessels operating in the area to exercise maximum caution and providing them with latest information,' he said, adding that their vessels have also been instructed to minimise the time in the Gulf. President Donald Trump said the US had 'obliterated' Iran's main nuclear sites in strikes over the weekend, joining an Israeli assault in an escalation of the conflict in the Middle East as Tehran vowed to defend itself. Iran's Supreme National Security Council must make the final decision on whether to close the Strait of Hormuz, Iran's Press TV said on Sunday, after parliament was reported to have backed the measure. Iran has long used the threat of closing the Strait, through which around 20 per cent of global oil and gas demand flows, as a way to ward off Western pressure which is now at its peak following the US strikes.
