71 killed in Israeli attack on Iran prison, official says

President Donald Trump said he doesn't envision Iran getting back into the "nuclear business" anymore.

Despite reports that intelligence found that U.S. strikes on Iran did not completely destroy the country's nuclear program and only set back its the nuclear program by months, Trump has insisted otherwise on Wednesday.

"The site was obliterated just like I said it was," Trump said during a press conference at the NATO Summit on Wednesday.

"Issue the report when you know what happened," Trump said. "The report was not a complete report."

At the NATO Summit in The Hague Wednesday morning, President Donald Trump pointed to a reported statement from the Israel Atomic Energy Commission (IAEC) -- which was circulated by the White House -- to support his assertion that Iran’s nuclear facilities were obliterated in the U.S. strike.

"Great statements just came out from the Israeli Atomic Energy Commission and from Iran, as you know, that it was complete, total destruction," Trump told reporters during a bilateral meeting with Dutch Prime Minister Dick Schoof.

The statement, shared by the White House "on behalf of the Israel Atomic Energy Commission," contradicts early U.S. intel assessments that found Iran’s nuclear program was only set back a few months.

"The devastating U.S. strike on Fordo destroyed the site's critical infrastructure and rendered the enrichment facility inoperable. We assess that the American strikes on Iran's nuclear facilities, combined with Israeli strikes on other elements of Iran's military nuclear program, has set back Iran's ability to develop nuclear weapons by many years," the IAEA said in a statement.

The Iranian regime executed three more prisoners on Wednesday over allegedly spying for Israel, according to Mizan, the official news agency of the Islamic Republic judiciary.

Iran’s state-run Press TV claims that more than 700 people with alleged ties to Israel’s Mossad intelligence agency have been arrested in recent days.

President Donald Trump again claimed "total obliteration" of Iran's nuclear program during the NATO summit in the Netherlands on Wednesday, dismissing a Pentagon report suggesting the joint U.S.-Israeli strikes on Tehran's facilities may have only set the program back by several months.

"I believe it was total obliteration," Trump told reporters speaking alongside NATO Secretary General Mark Rutte.

Trump was responding to assessments made in a preliminary analysis by the Defense Intelligence Agency and U.S. Central Command. Two people familiar with the report told ABC News it suggested the strikes did limited damage and that Iran was able to relocate highly enriched uranium stocks before the strikes occurred.

"I believe they didn't have a chance to get anything out, because we acted fast," Trump said. "If it would have taken two weeks, maybe. But it's very hard to remove that kind of material, very hard and very dangerous. Plus, they knew we were coming, and if they know we're coming, they're not going to be down there."

Trump insisted Iran's nuclear program had been set back "basically decades," adding, "It's gone for years."

Asked if they could rebuild and whether the U.S. would strike again, Trump said that would be someone else's problem.

"I'm not going to have to worry about that," he said. "It's gone for years, years, very tough to rebuild, because the whole thing is collapsed. In other words, inside, it's all collapsed. Nobody can get in to see it, because it's collapsed."

Asked if he trusted the U.S. intelligence assessment, the president said the initial report was "very inconclusive. The intelligence says we don't know, it could have been very severe, that's what the intelligence says. So I guess that's correct, but I think we can take the 'we don't know.' It was very severe. It was obliteration."
