'They got hit hard': Trump says Israeli attack on Iran has been 'excellent', warns 'there's more to come'

US President Donald Trump on Friday said the Israeli attack on Iran has been "excellent" and warned there was much more to come.

"I think it's been excellent. We gave them a chance and they didn't take it. They got hit hard, very hard. They got hit about as hard as you're going to get hit. And there's more to come. A lot more," Trump was quoted as saying by an ABC reporter on X.

On whether the United States participated in the attack in any way, Trump responded by saying "I don't want to comment on that."

Earlier in the day, Trump urged Iran to "make a deal," warning that there will be more "death and destruction". His remarks came after Israel pounded Iran in a series of air raids on Friday, striking 100 targets.

The operation killed senior figures -- among them the armed forces chief and top nuclear scientists -- and Iran has called Israel's wave of strikes a "declaration of war."

On Friday morning, Trump said: "I gave Iran chance after chance to make a deal."

He added that Israel -- which Trump has aligned Washington to since his return to the White House -- has a lot of weapons thanks to the United States and "they know how to use it."

"There has already been great death and destruction, but there is still time to make this slaughter, with the next already planned attacks being even more brutal, come to an end," Trump said on his Truth Social platform.

"Iran must make a deal, before there is nothing left... JUST DO IT, BEFORE IT IS TOO LATE," he said.

Trump earlier told Fox News he had been made aware of the Israeli strikes before they happened, and stressed that Tehran "cannot have a nuclear bomb," the US broadcaster said.

He also said that "we are hoping to get back to the negotiating table," according to Fox News.

During Trump's first term, he pulled the United States out of a landmark agreement to relieve sanctions on Iran in return for curbs on its nuclear program.

Fox News also reported that Trump's administration reached out to at least one key Middle Eastern ally to acknowledge that the strike was going to happen, but said the United States was not involved.

"Trump noted the US is ready to defend itself and Israel if Iran retaliates," Fox News said.

Secretary of State Marco Rubio said earlier Thursday that the United States was "not involved in strikes against Iran and our top priority is protecting American forces in the region."

"Let me be clear: Iran should not target US interests or personnel."

Trump will be attending a National Security Council meeting Friday morning.
