President Donald Trump took to his social media platform on Sunday night to further detail the U.S. strikes against Iran's nuclear facilities.

"Monumental Damage was done to all Nuclear sites in Iran, as shown by satellite images. Obliteration is an accurate term!" the president wrote on Truth Social.

Several B-2 bombers were used in strikes on three of Iran's nuclear facilities -- Fordo, Natanz and Isfahan. More than 125 aircraft participated in the mission, including seven B-2 Spirit stealth bombers, according to U.S. officials.

Trump did not mention which location he was specifically referring to, but said, "The white structure shown is deeply imbedded into the rock, with even its roof well below ground level, and completely shielded from flame."

"The biggest damage took place far below ground level. Bullseye!!!" Trump added of the strikes.

In an early morning message local time, Iran’s supreme leader, Ayatollah Ali Khamenei, said the "punishment" of Israel will continue.

Khamenei did not mention the United States or President Donald Trump in his statement.

"The Zionist enemy has made a grave mistake, committed a great crime; it must be punished and is being punished; it is being punished right now," Khamenei wrote.

Senior FBI and Homeland Security officials hosted a conference call with some of the nation's governors and top law enforcement officials to discuss how the U.S. missile strikes in Iran impact an already dangerous threat environment, sources told ABC News.

The call included hundreds of state and local law enforcement officials from around the country.

An FBI official said that the agency's "posture is going to be enhanced," with the FBI asking more personnel to be in the office, and continuing to "canvas sources" and monitoring intelligence.

Sources described the call with governors as short, and without a lot of specifics, saying there is currently no specific intelligence of a direct, credible threat against the U.S. homeland. It was meant to ensure that states are aware of the current threat environment and to encourage them to reach out to relevant state agencies, infrastructure partners and others who may be at risk, sources said.

The calls come after Homeland Security issued a bulletin calling on the public to report anything suspicious to officials with DHS Secretary Kristi Noem stating flatly that what’s happening in Iran brings the potential for increased threats to the homeland in the form of "possible cyberattacks, acts of violence and antisemitic hate crimes."

The State Department has issued a new worldwide caution alert prompted by the conflict between Israel and Iran, saying there is "potential for demonstrations against U.S. citizens and interests abroad."

“The conflict between Israel and Iran has resulted in disruptions to travel and periodic closure of airspace across the Middle East.  There is the potential for demonstrations against U.S. citizens and interests abroad. The Department of State advises U.S. citizens worldwide to exercise increased caution,” the alert reads.

Earlier this month, the State Department issued a regional alert related to the conflict, advising Americans in North Africa and the Middle East to exercise increased caution.

In October 2023, the U.S. issued a similar worldwide caution alert stemming from the Oct. 7 attacks on Israel and ensuing military campaign in Gaza.

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.”
