The expanding war in Iran entered its second week on Saturday amid renewed uncertainty about how or when hostilities will end, as U.S. President Donald Trump declared he would only accept Tehran's "unconditional surrender" and Israel traded fresh attacks with Iran and Lebanon.

The Israeli military said it had begun a “broad-scale” attack in Iran’s capital, hours after hitting Hezbollah strongholds in Lebanon. The Pentagon said Iran’s retaliatory missile strikes were decreasing.

The Red Crescent Society said the death toll in Iran had risen to 787 since the start of the attacks last week.

Israel made the announcement only hours after it had unleashed a major bombardment Thursday evening on a Hezbollah stronghold in the southern suburbs of Beirut, in another sign that Lebanon is fast becoming a new front in the widening conflict involving the United States, Israel and Iran. A series of airstrikes caused huge explosions in the Dahiya area, on the outskirts of the city, in the most intense attack since a cease-fire in late 2024 halted fighting between Israel and the Lebanese militant group Hezbollah. At least three buildings totally collapsed. Hundreds of displaced people were sleeping on the streets of downtown Beirut, some huddling around small fires to stay warm. The intensified bombardment came not long after Israel military officials acknowledged that their forces had moved deeper into Lebanon than previously disclosed and Israeli armed vehicles began massing at the border. The Israeli military had said earlier that it was going to hit targets in the Dahiya, warning people to evacuate to the north and setting off a panicked exodus on Thursday. The New York Times In Washington, President Trump said that he should have a role in choosing Iran’s new leader, and that Mojtaba Khamenei, a son of the former leader Ayatollah Ali Khamenei — who appears to be the leading candidate — to succeed his father, was an “unacceptable” choice. Mr. Trump’s comments, in interviews with Reuters and Axios, were the most explicit he has made about his view of an American role in creating a new government in Tehran.
