Iran live updates: US strikes Iran after 'unprovoked attacks' on warships

President Donald Trump, speaking to reporters on Thursday, said the U.S. military struck Iranian targets earlier after "they trifled with us," but that the fragile ceasefire is still on.

"They trifled with us today. We blew them away," Trump said.

Earlier, U.S. Central Command said three U.S. Navy destroyers were crossing the Strait of Hormuz when they came under fire from Iranian missiles and drones, and the U.S. launched "self-defense" strikes in response.

"They should not have done that today," Trump said. "We thought they might. We didn't know, but we were prepared. They shot missiles. Every missile was knocked down, every drone was knocked down, and the people that shot it are no longer with us."

Trump made his comments during an impromptu visit to the Lincoln Memorial Reflecting Pool, which is undergoing renovations.

Trump also said that the proposal between the two countries is "more than a one-page offer."

Sources have told ABC News that a major sticking point remains the future of Iran’s nuclear weapons program, and the president vowed not to let the country obtain or develop one.

Trump also said that a deal could happen "any day" but it also "might not happen" -- a sentiment he’s repeated several times throughout the course of the war.

President Donald Trump reiterated his threat for Iran to agree to make a deal to restart negotiations to end the war -- or face attacks again -- after the U.S. military said Iran fired "unprovoked" attacks on three U.S. Naval destroyers in the Strait of Hormuz.

"[J]ust like we knocked them out again today, we'll knock them out a lot harder, and a lot more violently, in the future, if they don't get their Deal signed, FAST!" Trump said on social media.

Trump said the three U.S. warships "transited, very successfully, out of the Strait of Hormuz, under fire."

"There was no damage done to the three Destroyers, but great damage done to the Iranian attackers," Trump said.

The president said Iran attacked the warships with missiles and drones, which the U.S. destroyed.

Following strikes between the U.S. and Iran, President Donald Trump told ABC News the ceasefire is not over.

"The ceasefire is going. It's in effect," he said in a phone call.

He called the strikes a "love tap."

"It's just a love tap," he said.

The U.S. conducted "self-defense" strikes against Iranian targets after Iran fired at U.S. destroyers in the Strait of Hormuz on Thursday, according to U.S. Central Command.

"U.S. forces intercepted unprovoked Iranian attacks and responded with self-defense strikes as U.S. Navy guided-missile destroyers transited the Strait of Hormuz to the Gulf of Oman," CENTCOM said in a statement.

No U.S. assets were struck, it said.

CENTCOM said the USS Truxtun, the USS Rafael Peralta and the USS Mason were transiting the strait on Thursday when Iranian forces "launched multiple missiles, drones and small boats."

In response, U.S. forces targeted "Iranian military facilities responsible for attacking U.S. forces including missile and drone launch sites; command and control locations; and intelligence, surveillance and reconnaissance nodes," CENTCOM said.

The Islamic Revolutionary Guard Corps gave a contradictory account, saying in a statement that it had targeted U.S. warships in retaliation for U.S. strikes on an Iranian oil tanker headed toward the strait and civilian areas along the Iranian coast. 

The IRGC also claimed to have struck the warships, "inflicting substantial damage," which CENTCOM disputes.
