President Donald Trump made a scathing threat to Iran that it would face retaliation from the U.S. military "at levels never seen before" if it carried out an attack on forces or land in a post shared on his Truth Social account early Sunday (June 15) morning.

The president claimed that the U.S. had no involvement with Israel's overnight attack on Iran as the two countries continued to exchange aerial attacks.

"The U.S. had nothing to do with the attack on Iran, tonight," Trump wrote in the post shared about half an hour after midnight. "If we are attacked in any way, shape or form by Iran, the full strength and might of the U.S. Armed Forces will come down on you at levels never seen before. However, we can easily get a deal done between Iran and Israel, and end this bloody conflict!!!"

Israel initially launched its unprecedented 'Rising Lion' attack, which was reported to have killed Gen. Bhossein Salami, head of Iran's Revolutionary Guard, Mohammad Bagheri, chief of the Iranian military, Gholam Ali Rashid, head of the country's emergency command and six nuclear scientists, early Friday (June 13) morning. Iran retaliated with several strikes of its own, killing 10 people, including two children, and injuring more than 200 in Tel Aviv, according to the New York Post.

Israeli Prime Minister Benjamin Netanyahu publicly confirmed the initial attack launched by his military and said it would continue for many days.

“Moments ago, Israel launched operation Rising Lion, a targeted military operation to roll back the Iranian threat to Israel’s very survival,” he said during a televised address via CNN. “This operation will continue for as many days as it takes to remove this threat.”

Netanyahu said Iran had a program to develop and "could produce a nuclear weapon" had it not been stopped by Israel's attack.

“This is a clear and present danger to Israel’s very survival,” Netanyahu added, noting that the attack "struck at the head of Iran's nuclear weaponization program.

Iran quickly called for a "declaration of war" with Supreme Leader Ayatollah Ali Khamenei vowing for "severe punishment" after the attacks.
