President Donald Trump announced a ceasefire between Israel and Iran, concluding the first direct war between the two longtime rivals.

In a post on Truth Social, Trump congratulated Israel and Iran, announcing a “Complete and Total CEASEFIRE” beginning “approximately 6 hours from now, when Israel and Iran have wound down and completed their in progress, final missions!” The end of hostilities will begin with a 12-hour ceasefire and, if held, will signal an end to the war, Trump said.
