Trump says damage to Iran's nuclear sites is 'far below ground level'

Sen. Jack Reed, D-R.I., told ABC News that President Donald Trump’s rebuke of his own intelligence chief is "shocking" and suggested Trump is disavowing his intelligence community for political reasons.

"It’s shocking to me that the president would dismiss his intelligence chief, who he picked," Reed, who is a ranking member of the Senate Armed Services Committee, told ABC News.

"This might not be a question of intelligence. This might be a question of political positioning, regardless of the intelligence," Reed said.

Weeks ago, U.S. Director of National Intelligence Tulsi Gabbard testified that the intelligence community continues to assess "Iran is not building a nuclear weapon, and Supreme Leader Khamenei has not authorized the nuclear weapons program that he suspended in 2003."

On Friday, Trump said both Gabbard and his intelligence community are flat out "wrong."

Trump is "in a position now where he’s contemplating an attack against Iran, and he has to have the conclusion that they do in fact have a nuclear – or the capacity to develop a nuclear weapon very quickly and the intent to do so – so that I think is prompting him to reject the intelligence community’s conclusions," Reed said.

Reed added that if Gabbard made a false statement in her testimony, “there would be an obligation to correct the record immediately, not just in the wake of this activity by the Israelis to suddenly conclude that she was totally wrong.”

At least 400 people have been killed and over 3,000 injured in Israeli strikes on Iran, according to the Iranian Ministry of Health.

"The majority of casualties and the injured have been civilians," the ministry said Saturday.

An Israeli military official says the IDF has assassinated three Iranian generals over the last day and struck the Isfahan nuclear site again.

The official also said Israel does not have a timeline for the war, only saying "we have goals and we won't stop until we reach them."

Meanwhile, the official denied that the IDF has targeted Iranian hospitals after the Iranian health ministry on Friday said that three Iranian hospitals have been hit, as well as six ambulances and a health center, though the official did say that hospitals could have been damaged from being near targets.

The State Department is aware of hundreds of Americans who have fled Iran amid the conflict with Israel and is also tracking unconfirmed reports of Americans who have been detained by the regime while attempting to leave, according to two officials familiar with the matter.

Americans who have left Iran have also reported that they faced delays and harassment from Iranian authorities while making their way out of the country, the officials said.

ABC News has requested comment from the State Department.
