71 killed in Israeli attack on Iran prison, official says

President Donald Trump does not believe Iran hid its enriched uranium before the U.S. launched strikes on its nuclear facilities, he told Fox News in an interview.

"I don't think they did. No, first of all, it's very hard to do. It's very dangerous to do, it is very heavy, very, very heavy. It's a very hard thing to do plus we didn't give much notice because they didn't know we were coming until just then. And nobody thought we'd go after that site because everybody said that site is impenetrable," Trump said.

"They moved themselves, they were all trying to live, they didn't move anything," Trump said.

Senate Republicans did not agree to push forward a resolution on Friday that would block President Donald Trump’s ability to use additional military force against Iran without explicit authorization from Congress.

By a vote of 53-47, a motion to advance Democratic Sen. Tim Kaine of Virginia’s measure invoking the 1973 War Powers Resolution failed, with Democratic Sen. John Fetterman of Pennsylvania -- a staunch supporter of Israel -- joining Republicans in opposing it.

One Republican, Sen. Rand Paul of Kentucky, crossed party lines to support the measure, which would have needed just a simple majority of 51 votes to pass.

Seven Republicans currently serving in the Senate voted for a similar Iran resolution back in 2020 -- a measure that was also championed by Kaine.

Ahead of the vote on Friday, one of those Republicans -- Sen. Todd Young of Indiana – said that he "does not believe an Iran war powers resolution is necessary at this time," in the wake of a security briefing held on Thursday by top members of Trump’s cabinet.

The resolution that failed on Friday would have required that any further hostilities with Iran have authorization by a declaration of war or an authorization of military force from Congress.

Kaine introduced the measure a few days before the U.S. bombed three of Iran’s critical nuclear sites.

On Friday during a speech on the Senate floor, Kaine said there is a prevailing need for the measure due to the shaky nature of the current ceasefire between Iran and Israel, which was announced by Trump earlier this week.

"I pray the ceasefire continues, but I fear we're going to be back here on this floor," he said. "And I hope when we are on this floor again, members of this body will stand for the proposition that has been part of our history -- that war is too big an issue to allow one person to make the decision that sends our sons and daughters into harm's way."

The International Atomic Energy Agency said radiation data in the Gulf indicates there have been no "important radioactive release from any damaged nuclear power reactor" as a result of strikes on nuclear facilities in Iran.

Director General Rafael Grossi said the "worst nuclear safety scenario was ... avoided" in attacks, which the IAEA said "severely damaged several nuclear facilities in Iran."

"This month’s Israeli and U.S. strikes on Iranian nuclear sites would have caused localized radioactive releases inside the impacted facilities and localized toxic effects, but there has been no report of increased off-site radiation levels," the IAEA said in its release.

"From a nuclear safety perspective, Iran’s Bushehr Nuclear Power Plant and the Tehran Research Reactor represented our main concern as any strike affecting those facilities – including their off-site power lines – could have caused a radiological accident with potential consequences in Iran as well as beyond its borders in the case of the Bushehr plant," Grossi said. "It did not happen, and the worst nuclear safety scenario was thereby avoided."

President Donald Trump said on Friday he would bomb Iran again "without a question" if intelligence were to find that Iran can enrich uranium to a level higher than what he is comfortable with.

"Without a question. Absolutely," he told reporters in the White House briefing room.

"They're exhausted. The last thing they are thinking about is nuclear [weapons]," Trump said of Iran.

Responding to Ayatollah Ali Khamenei's claim that Iran won the war, Trump said, "You got beat to hell. Israel was beat up too, they were both beat up."
