Dubai | Lebanon's government says it considers Hezbollah's military activities illegal acts and says the group should hand over its weapons.
Lebanese Prime Minister Nawaf Salam said only the state is the side that decides whether to go to war or peace. He added on Monday that all of Hezbollah's military activities are banned and that Hezbollah should only work in politics.
The government called on security agencies to prevent the firing of missiles or drones and detain those behind it.
The US military said on Monday that Kuwait "mistakenly shot down" three American F-15E Strike Eagles during a combat mission as Iran attacked the country.
The US military's Central Command said the combat included attacks from Iranian aircraft, ballistic missiles and drones -- the first time Iran's ageing combat fleet has been engaged in the war.
"The US Air Force fighter jets were mistakenly shot down by Kuwaiti air defences," it said. "All six aircrew ejected safely, have been safely recovered, and are in stable condition. Kuwait has acknowledged this incident, and we are grateful for the efforts of the Kuwaiti defence forces and their support in this ongoing operation."
Iran and Iranian-backed militias fired missiles at Israel and Arab states, apparently hitting the US Embassy compound in Kuwait, while Israel and the United States pounded targets in Iran as the war expanded on Monday with statements of defiance and increasing casualties.
At least 555 people have been killed in Iran so far by the US-Israeli campaign, the Iranian Red Crescent Society said, and more than 130 cities across the country have come under attack. Eleven people have been killed in Israel and 31 in Lebanon, according to authorities there.
In Kuwait, fire and smoke rose from inside the US Embassy compound, and the defence ministry said "several" American warplanes had also crashed in the country. The ministry did not elaborate on what caused the crashes or how many aircraft were involved, but said the pilots were taken to a hospital and were in stable condition.
Iranian state television claimed Iran had targeted US aircraft, without elaborating. The US military did not immediately respond to a request for comment.
The embassy compound was hit not long after the US issued a warning to Americans there to take cover and for others to stay away. There were no immediate reports of damage or casualties.
Multiple airstrikes hit Tehran, Iran's capital, on Monday afternoon, while top Iranian security official Ali Larijani vowed on X that "we will not negotiate with the United States." In Iraq, a pro-Iranian militia claimed responsibility for a drone attack targeting US troops at the Baghdad airport, the day after it said it fired at a US base in the city of Irbil in the north, and Cyprus said a drone attack targeted a British base on the Mediterranean island nation.
Israel and the US bombed Iranian missile sites and targeted its navy, claiming to have destroyed its headquarters and multiple warships.
Iran expands attacks to regional oil infrastructure
World markets were rattled by the fighting, and oil prices soared. Saudi Arabia's Ras Tanura oil refinery came under a drone attack on Monday, with defences downing the incoming aircraft, a military spokesman told the state-run Saudi Press Agency.
Online videos from the site appeared to show thick black smoke rising after the attack. Even successfully intercepted drones cause debris that can spark fires and injure those on the ground.
Ras Tanura, near the city of Dammam in eastern Saudi Arabia, is one of the world's largest oil refineries with a capacity of over half a million barrels of crude oil a day. It was temporarily shut down as a precaution after the attack, Saudi state television reported.
Oman said a bomb-carrying drone boat exploded against a Marshall Islands-flagged oil tanker in the Gulf of Oman on Monday, off the coast of the sultanate's capital of Muskat, killing one mariner. The state-run Oman News Agency said the dead crew member was from India.
Earlier in the day, debris fell on Kuwait's Ahmadi oil refinery, injuring two workers, after drones were shot down, the state-run KUNA news agency reported.
Iran's decision to expand its attacks to major regional oil infrastructure adds a new element to the war gripping the Middle East, directly targeting the lifeblood of the area's economy.
"The attack on Saudi Arabia's Ras Tanura refinery marks a significant escalation, with Gulf energy infrastructure now squarely in Iran's sights," said Torbjorn Soltvedt, an analyst at the risk intelligence company Verisk Maplecroft.
"An extended period of uncertainty lies ahead as Iran seeks to impose a heavy economic cost by putting tankers, regional energy infrastructure, trade routes and US security partners in the crosshairs," he added.
Iran has also threatened ships in the Strait of Hormuz, the narrow mouth of the Persian Gulf through which a fifth of all oil traded passes. Several ships have been attacked as well.
Sascha Bruchmann, a defence analyst with the International Institute for Strategic Studies in Bahrain, told The Associated Press that Iran's goal in hitting energy infrastructure is to "cause global backlash." So far, however, "this is not the wholesome destruction of critical infrastructure the Iranian regime seeks," Bruchmann said.
Iran's Ambassador to the UN nuclear watchdog, the International Atomic Energy Agency, Reza Najafi, told reporters that the US-Israeli airstrikes had targeted Iran's Natanz nuclear enrichment site on Sunday.
"Again, they attacked Iran's peaceful safeguarded nuclear facilities yesterday," he said. "Their justification that Iran wants to develop nuclear weapons is simply a big lie." Israel and the US have not acknowledged strikes at the site, which the US bombed back in the 12-day war between Iran and Israel in June. The Israeli military also did not immediately comment on Najafi's allegation.
Israel has not publicised specific targets in Iran but has said that it is targeting "leadership and nuclear infrastructure."
Hezbollah fires on Israel, prompting a massive response
As the attacks on Iran continued, Hezbollah said it fired missiles from Lebanon into Israel early Monday in response to the killing of Iranian Supreme Leader Ali Khamenei and "repeated Israeli aggressions." There were no reports of injuries or damage, and Israel said that it had intercepted one projectile while several fell in open areas.
Israel retaliated with strikes on Lebanon, killing at least 31 people and wounding 149 others, according to Lebanon's Health Ministry. About two-thirds of the dead were in the country's south.
Lebanon's government said it was holding an emergency meeting after Hezbollah's attack on Israel triggered the Israeli airstrikes.
Iran has been firing missiles at Israel and Arab states in a counteroffensive since the joint American-Israeli attack Saturday that killed Khamenei and many top Iranian officials.
Casualties rise as attacks spread
Gulf Arab states have warned that they could retaliate against Iran after strikes that hit key sites and killed at least five civilians, and US President Donald Trump promised Washington would "avenge" the deaths of three American troops who were killed in Kuwait, while predicting more casualties.
"Sadly, there will likely be more before it ends," Trump said. "That's the way it is." Trump has urged Iranians to "take over" their government and, while he has also signalled he would be open to dialogue with new leadership there following the death of Khamenei, suggested Sunday there was no end in sight to the military operations.
"Combat operations continue at this time in full force, and they will continue until all of our objectives are achieved," he said in a video message. "We have very strong objectives," he added, without elaborating.
The US military said B-2 stealth bombers struck Iran's ballistic missile facilities with 2,000-pound bombs. Trump said on social media that nine Iranian warships had been sunk and that the Iranian navy's headquarters had been "largely destroyed." Others have mostly stayed out of the war and pressed for diplomacy. But in an indication that the conflict could draw in other nations, Britain, France and Germany said Sunday they were ready to work with the US to help stop Iran's attacks.
Early Monday, Cyprus said an uncrewed drone "caused limited damage" when it hit a British air base on the southern coast. Further details were not immediately available, but it came after British Prime Minister Keir Starmer said the UK would help the US in the war against Iran.
The weekend attacks were the second time in eight months that the US and Israel had combined against Iran, in a startling show of military might for an American president elected on an "America First" platform and pledged to keep out of "forever wars." In the 12-day war last June, Israeli and American strikes greatly weakened Iran's air defences, military leadership and nuclear program. But the killing of Khamenei, who ruled Iran for more than three decades, creates a leadership vacuum, increasing the risk of regional instability.
Iranian proxies join the fray
Hezbollah's launch of missiles at Israel was the first time in more than a year that the militant group has claimed an attack.
Iran's proxies were a chief concern for American and Israeli officials before they suspended negotiations with Iran last week and moved ahead with strikes on Iran.
Israel said the Lebanese militant Hezbollah group had "joined the campaign" alongside Iran as it retaliated with strikes on Beirut, Lebanon's capital.
Associated Press journalists in Beirut were jolted awake by a series of loud explosions that shook buildings and caused windows to shatter. Warplanes could be heard flying low overhead.
"The strikes continue," said Maj. Gen. Rafi Milo, head of Israel's Northern Command. "Their intensity will increase." The Iraqi Shiite militia Saraya Awliya al-Dam claimed a drone attack on Monday targeting US troops at the airport in the Iraqi capital, Baghdad, further widening the retaliation over the killing of Khamenei. It had claimed a drone attack on Sunday against a US air base in Irbil, in Iraq's north.
The group is one of a number of Shiite militias operating in Iraq. The US and Iraq did not immediately comment on the claims.
In the Persian Gulf, Iran's retaliatory strikes pushed the conflict into cities that have long marketed themselves as regional safe havens. Three people were reported killed in the United Arab Emirates, and one each in Kuwait and Bahrain.
In the United Arab Emirates, authorities said most Iranian missiles and drones were intercepted. But some either got through or fell as debris, causing the deaths and significant damage. Bahrain and Kuwait said Iranian strikes in both countries hit civilian targets outside the US bases where Iran had pledged to retaliate.
WHO calls for the protection of civilians
Tehran's streets have been largely deserted with people sheltering during airstrikes. The paramilitary Basij force, which has played a central role in crushing recent protests, set up checkpoints across the city, according to witnesses.
In the northern Iranian city of Babol, a student, speaking anonymously over concerns of retribution, told the AP that armed riot police were on the streets Saturday night and into the early hours of Sunday after the death of Khamenei.
"We don't know whether to be happy about the elimination of the criminals who oppress us or to remain silent in the face of the US and Israel's war against the country and its interests and the terror that is taking place," he said.
In Israel, rescue services have confirmed several locations have been hit by Iranian missiles, including Jerusalem and a synagogue in Beit Shemesh, where nine people were killed and 28 wounded, bringing the overall death toll in the country to 11.
The World Health Organisation called on Monday for sparing civilians and healthcare facilities in the Middle East amid the escalating conflict.
"The protection of civilians and health care must be absolute," Hanan Balkhy, regional dietitian at WHO, wrote on social media. "All parties must … ensure medical facilities remain protected."
