President Donald Trump said in a post to Truth Social early Sunday morning that the "U.S. had nothing to do with the attack on Iran, tonight."

"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," the president added. "However, we can easily get a deal done between Iran and Israel, and end this bloody conflict!!!"

Israeli Prime Minister Benjamin Netanyahu's office said on Sunday that at least 13 people have been killed since Friday in Israel by Iranian strikes, as Tehran retaliates to Israel's ongoing attacks on Iranian nuclear facilities, military sites and leaders.

Two consecutive nights of Iranian attacks saw around 200 ballistic missiles fired into the country, the prime minister's office said, with 22 places in Israel hit either directly or by falling missile debris.

At least 380 people have been injured, the prime minister's office said, nine seriously.
