BEIRUT/WASHINGTON/JERUSALEM — On Friday, Israel dramatically intensified its military operations by launching strikes on Beirut following an extraordinary directive for a full evacuation of the southern suburbs of the Lebanese capital. This move marks a significant escalation in the conflict against Iran that began a week ago, with support from the United States.

In addition to the actions in Lebanon, Israel also initiated another round of assaults on Iran. The Israeli military announced that 50 warplanes targeted a bunker located beneath the compound in Tehran that was used by Iran’s leadership, even after Supreme Leader Ali Khamenei was killed on the first day of the conflict.

In what could be one of the initial signs of potential diplomatic efforts to resolve the conflict, Iranian President Masoud Pezeshkian took to social media platform X to announce, “Some countries have begun mediation efforts.” However, he refrained from naming these nations or providing additional details.

Pezeshkian further emphasized, “Our commitment to lasting peace in the region is unwavering, yet we will not hesitate in defending the dignity and sovereignty of our nation. Mediation should focus on those who underestimated the resolve of the Iranian people and sparked this conflict.”

Under Iran’s political structure, the president holds a position that is subordinate to the supreme leader. However, following Khamenei’s death, Pezeshkian is part of a panel that has taken on the former leader’s responsibilities.

In a potentially provocative move, President Trump has insisted on having a say in the selection of Khamenei’s successor, which could further complicate the geopolitical landscape.

Israel extends bombing to Lebanon

Israel has extended its bombing ​to Lebanon to root out Hezbollah, the Shi’ite militia allied to Iran that has been a dominant faction in Lebanese politics since the 1980s. Hezbollah fired on Israel this week to avenge the ⁠death of Khamenei.

Explosions lit up the night sky over Beirut’s southern suburbs.

The Israeli military said it carried out 26 waves of strikes overnight against Hezbollah command centers and weapons storage.

“We’re sleeping here in the streets — some in cars, some on the street, ​some on the beach,” said Jamal Seifeddin, 43, who fled Beirut’s southern suburbs and spent the night on the streets in the capital’s downtown district. “I’ve never slept on the ground like this. I’ve been forced to. No one even brought a blanket.”

Israel has intervened in ​Lebanon repeatedly over decades, most recently in a campaign that weakened Hezbollah in 2024.

But the ferocity of Friday’s strikes had little precedent even in the long history of war in the Lebanese capital.

Israel ordered residents to evacuate the entire southern section of Beirut, home to hundreds of thousands of people. During previous campaigns, it had ordered only smaller evacuations of specific areas.

Inside Israel, explosions could be heard as Israeli defenses activated to shoot down incoming Iranian fire. Overnight, Iranian drones also attacked the Al Udeid airbase in Qatar, the biggest US base in the Middle East, Qatari officials ​said. There were no reported casualties.

‘We’re going to have to choose that person’: Trump

In insisting on the right to help choose Iran’s next leader — meant to be a senior Shi’ite Muslim cleric selected by a panel of religious experts — Trump made his ​most explicit demand for control over a country of more than 90 million people.

The remarks could make it more difficult to end the war quickly in a deal that would leave Iran’s system of clerical rule in place.

“We’re going to have to choose that person along with Iran. ‌We’re going to ⁠have to choose that person,” Trump said Thursday in a telephone interview with Reuters.

Israel has said openly it aims to overthrow Iran’s ruling system. Washington has been more circumspect, saying its goal is to eliminate Iran’s ability to project force beyond its borders, while also inviting Iranians to rise up and topple their government.

There was no immediate Iranian response to Trump’s remarks. Iran has cast the war as an unprovoked attack and describes the killing of its leader, Khamenei, as an assassination.

It says the panel that will choose the new leader is conducting its work.

Iranian officials initially said the new leader could be chosen soon, and the leading candidate was Khamenei’s son Mojtaba, a powerful hardliner. But plans for a quick dynastic succession may have stalled since a three-day period of mourning for Khamenei ​was postponed indefinitely on Wednesday.

Some Iranians openly celebrated the death of ​Khamenei, weeks after security forces under his control killed thousands ⁠of protesters in the worst domestic unrest since the revolutionary era. But there has been little sign of opposition to the authorities during the airstrikes, with activists saying it is not safe to return to the streets.

‘Existential war’ for Iran

Iran’s Deputy Foreign Minister Saeed Khatibzadeh said Iran was not intentionally targeting its Arab neighbors, only the US bases on their soil.

“This was an ‘existential war’ for ​Iran, leaving us with no choice but to respond wherever American attacks originate from,” he said at a conference in New Delhi on Friday.

Two US officials told Reuters that military investigators believed ​it was likely that US forces ⁠were responsible for an apparent strike on an Iranian girls’ school that killed scores of children on Saturday.

The investigators have not yet reached a final conclusion.

At least 1,230 people have been killed in Iran since the fighting began a week ago, according to the Iranian Red Crescent Society.

The Lebanese health ministry has reported 123 people killed and 683 wounded as a result of Israeli attacks. At least 10 Israelis have been killed by Iranian attacks.

In his remarks to Reuters, Trump also encouraged Iranian Kurdish forces based across the border in Iraq to launch ⁠attacks against Iran, ​a move that would open a ground front in the war.

“I think it’s wonderful that they want to do that, I’d be all for it,” Trump ​said.

Two Iranian drone attacks targeted an Iranian opposition camp in Iraqi Kurdistan on Thursday, security sources said. Three sources said Iranian Kurdish militias have consulted with the United States about whether and how to attack Iran’s security forces.
