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.

Trump spent his final day at NATO disputing intelligence that said U.S. strikes on Iran's nuke facilities set the country back only by months.

The president announced a truce and Israel later said its airports were returning to full activity and it was lifting restrictions on civilian movements.
