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.

President Donald Trump said a ceasefire between Iran and Israel was “in effect” on Tuesday, after expressing deep frustration with both sides for violating the agreement he brokered.

After twelve days of intense strikes between Israel and Iran – punctuated by the United States’ bombing of Iranian nuclear sites over the weekend and Tehran’s performative retaliation – a US-brokered ceasefire appeared to be holding on Tuesday.
