President Donald Trump said the strikes carried out in three Iranian nuclear sites resulted in them being "completely and totally obliterated," labeling the operation a "spectacular military success."
Trump concluded his speech by threatening Iran should it not return to the negotiation table.
"There will be either peace, or there will be tragedy for Iran," Trump said, adding that the US "will go for other targets" should that not be the case.
Trump shares post with 'Fordo is gone'
After announcing the US Air Force's airstrikes on three nuclear sites in Iran, US President Donald Trump re-shared a post on Truth Social which labels the site in Fordo, an underground nuclear site in Iran, as "gone."
Despite carrying out airtsrikes on nuclear sites across Iran, Israel refrained from attacking the Fordo site.
US bunker-busting bombs, which uses weight and sheer kinetic force to reach deeply buried targets, were needed to reach the underground site.
Earlier, Trump posted on his Truth Social account that a "a full payload of bombs was dropped" on the site, that is known to be located several dozen meters underground, making it more difficult to attack.
According the post, all planes that took part in the strikes left Iranian airspace.
"Congratulations to our great American warriors," Trump said, adding that it is now "time for peace."

How have US lawmakers reacted to Trump's decision?
The attack on Iran's nuclear facilities marks a significant shift for US President Donald Trump, who came to office promising he would keep the US out of foreign wars and often criticized military interventions.
Trump's decision to attack Iran has stirred a storm across the US political spectrum.
US House of Representatives Speaker Mike Johnson, a Republican of Louisiana, came out in favor of the attack, saying it "prevents the world's largest state sponsor of terrorism, which chants' Death to America,' from obtaining the most lethal weapon on the planet."
Senate Foreign Relations Committee Chairman Jim Risch, a Republican of Idaho, said: "This war is Israel's war, not our war, but Israel is one of our strongest allies and is disarming Iran for the good of the world."
Others, including Democrats as well as hardcore Trump supporters often referred to as "MAGA," criticized the decision.
US House Democratic Leader Hakeem Jeffries said: "President Trump misled the country about his intentions, failed to seek congressional authorization for the use of military force and risks American entanglement in a potentially disastrous war in the Middle East."
