President Donald Trump told ABC News on Tuesday morning he is "not happy" with either Israel or Iran after the opening hours of a nascent ceasefire between the two combatants were marred by reported exchanges. Trump said Iran and Israel both "violated" the ceasefire that he announced late on Monday, in comments made as he departed the White House.

Iran fired a final wave of deadly missiles at Israel before acknowledging the deal, while Israel said it accepted the proposal because all its military objectives were already achieved.

The U.S. Department of Homeland Security warned Americans of a "heightened threat environment" on June 22 that could include attacks on U.S. soil. That fear appeared to dissipate when Iran attacked a United States military base in Qatar June 23, injuring no one.
