Iran will fight on and keep the Strait of Hormuz shut as leverage against the United States and Israel, new Supreme Leader Mojtaba Khamenei said on Thursday in the first comments attributed to him since he succeeded his slain father.

Khamenei did not appear in person, and the remarks were read out by a state television presenter. No images have been released of him since an Israeli strike at the start of the war that killed much of his family, including his father and wife.

Thursday’s statement struck a defiant tone, with Khamenei calling on Iran‘s neighbors to shut US bases on their territory and warning that Iran would continue to target them.

“I assure everyone that we will not neglect avenging the blood of your martyrs,” said the hardline cleric who is close to Iran‘s top military force.

“The popular demand is to continue our effective defense and make the enemy regret it. The lever of blocking the Strait of Hormuz must continue to be used,” he added, referring to the shipping route through which a fifth of global oil normally passes along Iran‘s coast.

State television offered no explanation for why the message was read out rather than delivered in person. Iranian officials have said Khamenei was lightly wounded in the initial Feb. 28 airstrikes, but the extent of his injuries is unclear.

The prospect that one of the most severe disruptions ever to hit global energy supplies could drag on sent oil prices surging back above $100 a barrel, after falling back earlier in the week on hopes of a swift end to the conflict.

TANKERS ABLAZE IN IRAQI PORT

Shortly after the address was read out, the Revolutionary Guards announced they would keep the strait shut in line with his orders.

Two tankers were ablaze in an Iraqi port on Thursday after a hit by suspected Iranian explosive-laden boats, a clear sign of defiance toward US President Donald Trump, who said on Wednesday the United States had already won the war.

Images verified by Reuters as filmed from the Iraqi port of Basra showed ships engulfed in massive orange fireballs that lit up the night sky. At least one crew member was killed.

Hours earlier, three other ships were struck in the Gulf. Iran‘s Revolutionary Guards claimed responsibility for at least one attack – on a Thai bulk carrier that was set ablaze – saying it had disobeyed their orders. Another container vessel reported being struck by an unknown projectile near the United Arab Emirates.

In another front of the unpredictable war, Israeli airstrikes hit a building in central Beirut on Thursday, sending thick smoke above the Lebanese capital.

Israel also ordered residents out of another swathe of southern Lebanon, intensifying its offensive against the Iran-backed Hezbollah group after it fired its biggest volley of rockets into Israel since the start of the war.

So far the war has killed more than 2,000 people, including almost 700 in Lebanon.

AS DRONES FLY, TRUMP SAYS US WILL BENEFIT

Undermining US and Israeli claims to have knocked out much of Iran‘s stock of long-range weapons, more drones were reported on Thursday flying into Kuwait, Iraq, the UAE, Bahrain, and Oman.

Iran has said it will not let oil back through Hormuz until US and Israeli attacks cease, but Trump played down the surge in energy prices, saying Washington would ultimately benefit.

“The United States is the largest Oil Producer in the World, by far, so when oil prices go up, we make a lot of money,” he wrote on social media, adding that “of far greater interest and importance to me, as President, is stopping an evil Empire, Iran, from having Nuclear Weapons.”

The US is a net oil exporter but also the world’s biggest oil consumer, burning roughly twice as much as the European Union. Economists say sustained high prices would drive broad inflation.

In separate comments, Trump said the Iranian men’s national soccer team was welcome to participate in the 2026 World Cup, which the US is co-hosting, but added that it was not appropriate that they be there “for their own life and safety.”

‘SECURITY FORCES ARE EVERYWHERE’

Inside Iran, residents said security forces were increasing their presence on the streets to demonstrate continued control.

“Security forces are everywhere, more than before. People are afraid to come out, but supermarkets are open,” teacher Majan, 35, said by phone from Tehran.

Three sources told Reuters that US intelligence indicated that Iran‘s leadership remained largely intact and not at risk of imminent collapse.

Israel and the United States have called on Iranians to rise up and topple their clerical rulers. Many Iranians want change and some openly celebrated the elder supreme leader’s death on the war’s first day, after his forces had killed thousands of anti‑government protesters in January. But there has been no sign of organized dissent while the country is under attack.

TEHRAN SEEKS PROLONGED ECONOMIC SHOCK

Khamenei’s remarks reinforce Iran‘s message that its strategy now is to impose a prolonged economic shock to force Trump to back off. A spokesperson for Iran‘s military command said on Wednesday that the world should prepare for oil prices of $200 a barrel.

US Energy Secretary Chris Wright said on Thursday he did not expect that to happen, but did not totally rule it out. “I would say unlikely, but we are focused on the military operation and solving a problem,” Wright told CNN.

Thursday’s oil price surge came despite the announcement the previous day that developed countries would release 400 million barrels of oil from their strategic reserves, nearly half from the United States.

That is by far the biggest-ever coordinated intervention in oil markets. But releasing the reserves will take months, and account for just three weeks of supply from the blockaded strait.

“The only way to see oil prices trade lower on a sustained basis is by getting oil flowing through the Strait of Hormuz,” ING analysts said.

Israeli airstrikes hit a building in the heart of Beirut on Thursday and Israel ordered residents out of another swathe of southern Lebanon, intensifying its offensive against the Iran-backed Hezbollah terrorist group.

The airstrike at around 5:30 pm (1530 GMT) hit a building in the Bachoura neighborhood, around 1 km (mile) from the Lebanese government’s Grand Serail headquarters in downtown Beirut.

Before the strike, the Israeli military issued a warning telling residents they were near a Hezbollah facility against which it intended to action.

Israel launched an air and ground offensive last week against Hezbollah, which started the conflict when it launched attacks at Israel on March 2 that it said aimed to avenge the killing of Iran’s supreme leader at the start of the US-Israeli war on Iran.

Hezbollah has fired rockets and drones at Israel every day since, including its largest barrage late on Wednesday that triggered heavy Israeli strikes on Beirut‘s southern suburbs.

In the Wednesday night launches, Hezbollah said it had launched dozens of rockets into northern Israel as part of a “series of operations,” indicating there could be more to come. Lebanese security sources told Reuters more than 100 rockets were launched.

A senior Israeli defense official said Iran and Hezbollah had launched a joint missile attack, describing it as the first coordinated action against Israel since the war began.

Israel’s ambulance service said two people had been lightly wounded by the rockets.

The Israeli strikes on Beirut‘s southern suburbs began almost immediately after Hezbollah’s attack, sending half a dozen consecutive booms reverberating across the city. The Israeli military said it struck 10 Hezbollah structures within 30 minutes, including a headquarters of its elite Radwan unit.

Beirut‘s skyline was covered in thick smoke, Reuters footage showed. In one of the bombed locations, flickering orange flames were visible late into the night.

Israel’s military has repeatedly ordered residents of the southern suburbs to leave over the last week, prompting a displacement crisis as government shelters struggle to cope.

On Wednesday night, after strikes began, the Israeli military said it would “soon act with overwhelming force” against Hezbollah and that residents should leave immediately.

Israel has pounded Lebanon’s south and east and the capital’s southern suburbs, killing more than 600 people, according to Lebanese authorities. It has also ordered mass evacuations in those same areas, pushing more than 800,000 people out of their homes.

Israeli Defense Minister Israel Katz said the military had been instructed to expand its operations in Lebanon.

“We promised quiet and security to the communities of the north, and that is exactly what we will deliver,” he said at a meeting with senior military officials.

The Israeli military says it has struck hundreds of Hezbollah targets since March 2, launching daily airstrikes in the south, Beirut‘s southern suburbs, and the eastern Bekaa Valley.

Israel’s military ordered reinforcements to the area bordering Lebanon including its elite Golani Brigade and has also sent soldiers into southern Lebanon, establishing new positions there.

Reuters reported on Tuesday that Hezbollah fighters were braced for the possibility of a full-scale Israeli invasion of the south.

Lebanon said last year it aims to establish a state monopoly on arms and its cabinet last week outlawed Hezbollah’s military activities.

But Israel’s ambassador to the United Nations Danny Danon said on Wednesday that Beirut needed to take direct action.

“If Hezbollah is being dismantled, what are the evidence? What are the operations against the launch sites? Where are the seizures of their weapons? Where is your military?” Danon said.

A senior official from a Paris-based Iranian opposition group said on Thursday that the US-Israeli war on Iran would not topple the clerical leadership, arguing that only a popular uprising backed by internal resistance could do so.

Almost two weeks of bombing have killed around 2,000 people in Iran including supreme leader Ayatollah Ali Khamenei, and damaged much of its military and security apparatus.

Iran has responded in kind, throwing global energy markets and transport into chaos and spreading the conflict across the Middle East, while the Islamic Revolutionary Guard Corps has tightened its grip on power and threatened to crush any unrest.

“The 12-day war in June, and the current war, now in its 12th day, proved that bombings cannot overthrow the regime,” Mohammad Mohaddesin, head of foreign policy at the National Council of Resistance of Iran (NCRI), told a news conference.

“Even if you have 50,000 armed soldiers on the ground, you need the support of Iranian people. You need a popular uprising. The combination of this 50,000 or 20,000 or any other number with a popular uprising, then you have this power to overthrow the regime.”

Mohaddesin said he did not consider a deployment of US ground troops realistic.

The NCRI, also known by its Farsi name Mujahideen-e-Khalq, was listed as a terrorist organization by the United States until 2012.

It is banned in Iran, and it is unclear how much support it has there. However, along with its bitter rival, the monarchists backing Reza Pahlavi, exiled son of the toppled shah, it is one of the few opposition groups able to rally supporters.

Mohaddesin acknowledged that his group alone could not bring down the system. But he said mass protests, like those that raged in January until they were bloodily quashed, would resume once bombing stopped, and could eventually shift the balance.

“I cannot say how many months or a year, but … this is the track of overthrowing the regime,” he said.

Israeli officials have said that one of their objectives is to weaken the security apparatus so that Iran‘s people can take control of their own destiny.
