President Donald Trump has confirmed that Iranian Supreme Leader Ali Khamenei was killed in the joint U.S.-Israeli attack on Iran.
"Khamenei, one of the most evil people in History, is dead. This is not only Justice for the people of Iran, but for all Great Americans, and those people from many Countries throughout the World, that have been killed or mutilated by Khamenei and his gang of bloodthirsty THUGS," Trump said in a post on social media.

"This is the single greatest chance for the Iranian people to take back their Country. We are hearing that many of their IRGC, Military, and other Security and Police Forces, no longer want to fight, and are looking for Immunity from us," Trump added.
Despite Khamenei's death, Trump said the "heavy and pinpoint bombing" will continue, "uninterrupted throughout the week or, as long as necessary to achieve our objective."
Multiple Israeli officials tell ABC News that Israel has determined that Iran's Supreme Leader Ayatollah Ali Khamenei was killed in the joint U.S. and Israeli strikes on Tehran earlier Saturday. U.S. officials have been informed by the Israelis but have not independently confirmed the report, according to two U.S. officials.
President Donald Trump told ABC News he believes the supreme leader is dead, saying, "we believe so."
"I don't want to say anything definitively until I see things but we believe he is. And much of their leaders are gone," Trump told ABC News.

Earlier Saturday, an Iranian Foreign Ministry Spokesperson Esmaeil Baghaei denied reports that Khamenei and Iranian President Masoud Pezeshkian were killed in the strikes, saying they are "safe and sound," in an interview on ABC News Live.
The Israel Defense Forces said it believes almost the entirety of Iran’s military leadership was killed Saturday, including the head of the Iranian Security Council, the defense minister and a top intelligence official.
Among the officials are Ali Shamkhani, the secretary of the Iranian Security Council; Mohammad Pakpour, commander of the Islamic Revolutionary Guard Corps; and Aziz Nasirzadeh, the defense minister of Iran.

President Donald Trump expressed optimism about the U.S.-Israeli attack on Iran saying it is going "very well," speaking to ABC News by phone.
Asked about how long it will last, Trump said, "As long as we wanted to, actually. But it’s done such damage already. It’s like — they are incapacitated, essentially -- as long as we wanted to."
Asked about Iranian leadership and whether the U.S. believes they were killed in strikes, Trump said, "A lot of it is, yeah. But we don’t know all, but a lot of it is. Was a very powerful strike."
Asked about the next leadership and if a leader has been identified, Trump said "Yes. We have a very good idea."
