WASHINGTON — President Donald Trump announced a phased ceasefire deal between Iran and Israel, signaling an end to 12 days of escalating conflict. The ceasefire begins Tuesday at 4:00 GMT, with Iran halting operations first, followed by Israel 12 hours later.

The conflict, which claimed hundreds of lives in Iran and over 20 in Israel, saw the U.S. intervene with strikes on Iranian nuclear sites. Iran responded with missile attacks on a U.S. base in Qatar — an action Trump dismissed as “very weak.” No casualties were reported.

Trump said both nations agreed to remain peaceful during the ceasefire process. The deal comes amid growing global concern over potential regional war, with world leaders urging calm. The ceasefire is seen as a major step toward de-escalation.
