The conflict in Iran entered its second week on Saturday, with uncertainty mounting over how long the fighting will continue. U.S. President Donald Trump called on Tehran to accept “unconditional surrender,” while Israel continued exchanging attacks with Iran and Lebanon.
Trump’s remarks came shortly after Iranian President Masoud Pezeshkian suggested on social media that several unnamed countries had begun mediation efforts, briefly raising hopes for a possible resolution a week after U.S. and Israeli forces launched strikes on Iran.
“There will be no deal with Iran except UNCONDITIONAL SURRENDER!” Trump wrote on his Truth Social platform on Friday. He added that after such a step and the selection of a “great and acceptable leader,” the United States and its allies would help rebuild Iran’s economy and restore stability.
Trump has offered varying explanations of the objectives behind the military campaign, fueling concerns that the conflict could become prolonged. The fighting has already spread beyond Iran’s borders, rattling global financial markets and pushing oil prices sharply higher.
Iran has responded by launching attacks on Israel and on several Gulf states that host U.S. military bases. According to Iran’s ambassador to the United Nations, Amir Saeid Iravani, U.S. and Israeli strikes have killed at least 1,332 Iranian civilians and injured thousands more. Iranian attacks have killed 11 people in Israel and at least six U.S. service members.
Early Saturday, missiles were seen heading toward Israel after the Israeli military detected launches from Iran. Explosions were heard as Israeli air defenses intercepted incoming missiles.
Soon after, Israel said it launched a new wave of strikes targeting infrastructure in Tehran. Israeli forces also carried out attacks in neighboring Lebanon, claiming they were targeting Iranian and Hezbollah-linked sites.
Iran’s semi-official Tasnim news agency reported that Tehran’s Mehrabad Airport had been struck. There was no immediate response from Iran’s Islamic Revolutionary Guard Corps or from Hezbollah in Lebanon.
Meanwhile, flight operations resumed at Dubai International Airport, according to aviation tracking service Flightradar24.
On Friday, Israel said 50 of its warplanes struck a bunker in Iran reportedly used by senior leadership beneath the destroyed Tehran compound of slain Supreme Leader Ayatollah Ali Khamenei.
Israel has also intensified its campaign in Lebanon, launching heavy strikes on Beirut after ordering the evacuation of the capital’s southern suburbs. Israeli officials say the operation aims to weaken Hezbollah, the powerful Shi’ite militia that has played a dominant role in Lebanese politics since the 1980s.
Hezbollah fired rockets at Israel earlier this week, saying the attack was in retaliation for the killing of Khamenei on the first day of the war.
The escalating violence has displaced large numbers of civilians. “We’re sleeping on the streets—some in cars, some on the pavement, some on the beach,” said Jamal Seifeddin, 43, who fled Beirut’s southern suburbs.
The Norwegian Refugee Council estimates that around 300,000 people have been displaced in Lebanon over the past four days. Lebanon’s health ministry reports that Israeli strikes have killed at least 123 people and wounded 683 others.
The widening conflict has shaken global markets. European and U.S. stocks fell sharply on Friday, while oil prices surged to multi-year highs as the Strait of Hormuz—through which about one-fifth of the world’s oil passes daily—was effectively shut down.
To reassure energy shippers, the U.S. International Development Finance Corporation said Washington would provide up to $20 billion in reinsurance for potential losses in the Gulf region.
Trump also said the U.S. Navy could escort commercial ships in the Gulf. Iran’s Revolutionary Guards responded defiantly, with spokesperson Alimohammad Naini saying Iran “welcomes” any U.S. naval presence in the strait.
Reports have also suggested growing international involvement. The Washington Post reported that Russia is sharing intelligence with Iran on the locations of U.S. warships and aircraft in the Middle East, though Russian officials have not yet commented publicly.
Trump has repeated his demand that the United States have a role in choosing Iran’s next supreme leader—a proposal firmly rejected by Iran.
Ambassador Iravani said any new leadership would be chosen strictly according to Iran’s constitutional process and the will of the Iranian people, without foreign interference.
Iran has described the conflict as an unprovoked attack and labeled the killing of Khamenei an assassination.
Meanwhile, the Trump administration is working to replenish weapons supplies as the campaign continues. Trump met with executives from seven major defense contractors on Friday, saying they had agreed to accelerate production.
White House spokesperson Karoline Leavitt said the United States has sufficient weapons for the operation, which officials estimate could last four to six weeks.
The U.S. State Department also approved $151.8 million in emergency weapons sales to Israel, bypassing the usual congressional review. Secretary of State Marco Rubio said the move was necessary due to the urgent security situation.
Separately, U.S. military investigators are examining whether American forces were responsible for a strike that hit an Iranian girls’ school on the first day of the war, reportedly killing dozens of children. Officials say the investigation is ongoing and no final conclusion has yet been reached.
