Iran on Monday named Mojtaba Khamenei to succeed his father Ali Khamenei as supreme leader, signaling that hardliners remain firmly in charge, as the ​week-old US-Israeli war with Iran pushed oil above $100 a barrel.

Mojtaba, a cleric with influence inside Iran’s security forces and vast business networks under his father, had been viewed as a frontrunner ‌in the lead-up to Sunday’s vote by the Assembly of Experts, a body of 88 clerics tasked with choosing Ali Khamenei’s successor.

“By a decisive vote, the Assembly of Experts, appointed Ayatollah Seyyed Mojtaba Hosseini Khamenei as the third Leader of the sacred system of the Islamic Republic of Iran,” the Assembly said in a statement issued just after midnight Tehran time.

The position gives Mojtaba the final say in all matters of state in the Islamic Republic.

Mojtaba’s appointment will likely draw the ire of US President Donald Trump, who said on ​Sunday that Washington should have a say in the selection. “If he doesn’t get approval from us, he’s not going to last long,” he told ABC News.

Israel, ahead of the announcement, threatened to target whoever was ​chosen.

In an interview with the Times of Israel after the new supreme leader was named, Trump declined to respond, saying only “We’ll see what happens,” according to the newspaper. ⁠Trump also said in the interview that ending the war would be a “mutual” decision with Israeli Prime Minister Benjamin Netanyahu.

Mojtaba’s father, Supreme Leader Ali Khamenei, was killed in one of the first strikes launched against Iran more ​than a week ago.

Washington on Sunday ordered the departure of non-emergency employees at its embassy in Saudi Arabia, the latest drawdown of US diplomats as Iran has struck US facilities in the region.

The US military reported a seventh American ​has died from wounds sustained during Iran’s initial counter-attack a week ago, a day after Trump presided over the return to the United States of the remains of the six others killed.

The US-Israeli attacks have killed at least 1,332 Iranian civilians and wounded thousands, according to Iran’s UN ambassador.

Oil over $100 a Barrel 

The expanding war has severely impacted the oil trade and surging prices sparked a fall in share futures in Asia on Monday, amid fears of rising living costs. The dollar rose sharply against the euro and the yen.

US crude ​futures rose more than 20% in early trade on Monday, hitting their highest since July 2022, amid fears of tighter supply and prolonged disruptions to oil shipments through the Strait of Hormuz. Brent jumped 17% to $108.73 a barrel, ​having already soared 28% last week.

Trump, in a social media post, said oil prices “will drop rapidly when the destruction of the Iran nuclear threat is over,” and said the price ‌hike was “a very ⁠small price to pay for USA., and World, Safety and Peace.”

Defiance from Tehran 

Iranian state media said the leadership of Iran’s armed forces had pledged allegiance to Mojtaba Khamenei and the Islamic Revolutionary Guard Corps said in a statement they are ready to follow the new supreme leader.

The Assembly of Experts met on Sunday to elect a new supreme leader despite threats that the body would be targeted, Iran’s security chief, Ali Larijani, said on state TV after the announcement.

Mojtaba Khamenei could lead the country under the current sensitive conditions, Larijani said, calling for unity around the new leader.

Iran has launched strikes across the region in retaliation against US and Israeli attacks. The US State Department said on ​Sunday it had ordered non-emergency US government employees and ​their family members to leave Saudi Arabia due to ⁠safety risks, days after the embassy in the Saudi capital was damaged in a drone attack blamed on Iran.

Early on Sunday, the Saudi Defence Ministry said that it had shot down a drone that attempted to target the Diplomatic Quarter, a calm tree-lined neighbourhood on the city’s western edge that hosts most foreign missions including the US embassy.

The ​US has already raised its warning level for Saudi Arabia and allowed some personnel to leave the country, and has ordered the departure of staff at embassies ​in Qatar, Kuwait, Jordan and ⁠Bahrain since the outbreak of the war.

Israel continued to target senior Iranian figures, including Abolqasem Babaian, the recently appointed head of the military office of the supreme leader, saying he was killed in a Saturday strike.

‘Dangerous new phase' 

As fighting escalated on Sunday, day nine of the US-Israeli campaign against Iran, thick black smoke hung over Tehran, residents said, after strikes on oil storage facilities, opens new tab had lit up the night sky with plumes of orange flame.

Iran’s foreign ministry spokesperson Esmaeil Baghaei said the large-scale attack ⁠marked a “dangerous new ​phase” of the conflict and amounted to a war crime.

Israeli military spokesman Lieutenant Colonel Nadav Shoshani told reporters the depots were used to ​fuel Iran’s war effort, including producing or storing propellant for ballistic missiles. “They are a legal military target,” he said.

Netanyahu said his government would press on with the assault and strike Iran’s rulers “without mercy”.

“We have an organised plan with many surprises to destabilise the regime and enable change,” ​he said in a video statement.
