President Donald Trump rebutted allegations that the U.S. Armed Forces were involved in Saturday night’s attack against Iran and warned a military response at “levels never seen before” would be levied should the U.S. be attacked “in any way, shape or form by Iran.”

Iran suffered strikes on two of its oil depots in Tehran on Saturday and on its Iranian Defense Ministry Headquarters. While Israel took credit for the strikes, Trump took to Truth Social early Sunday to affirm he wasn’t involved.
