Senior clerics selected Mojtaba Khamenei to succeed his father after another day of strikes across the Middle East. A senior Iranian official warns the war is entering a "new phase."

• Iran’s new leader: Iran has named Mojtaba Khamenei the country’s next supreme leader, state media reports, cementing hardliners’ grip on power following the killing of his father Ayatollah Ali Khamenei. US President Donald Trump previously said Khamenei’s son would be an “unacceptable” selection, and warned a new leader won’t “last long” without Trump’s support.

• US service member killed: A seventh US service member has died from wounds sustained in the war with Iran, US Central Command announced.

• School strike: New video appears to confirm a US airstrike targeted a naval base next to an Iranian elementary school where more than 160 students were killed last month, adding to a body of evidence contradicting Trump’s recent claims casting blame on Iran.

• New phase of the war: A senior Iranian official told CNN the Middle East conflict is entering a “new phase” and threatened retaliatory strikes on energy infrastructure across the region.

Iran said at least 104 crew members were killed and 32 others injured in a US attack on the Iranian warship Iris Dena last week, the semi-official Fars News Agency reported Sunday, citing official sources.

US Defense Secretary Pete Hegseth said Wednesday that a US submarine sank an Iranian warship in international waters.

The injured crew members were taken to a hospital in Sri Lanka for treatment after authorities there launched a rescue mission, according to Fars.

President Donald Trump said Sunday that the new supreme leader “is not going to last long” without his approval as Iran prepares to announce a successor to its longtime ruler, Ayatollah Ali Khamenei.

“He’s going to have to get approval from us,” Trump told ABC News in an interview. “If he doesn’t get approval from us he’s not going to last long.”
