Trump says Iran ceasefire proposal 'very significant step'

U.S. President Donald Trump said Monday the United States has studied a proposal for a 45-day ceasefire in the Iran war, a move he called a "very significant step" in the conflict.

"It's a significant proposal, it's a significant step. It's not good enough, but it's a very significant step," Trump told reporters at the White House, adding that intermediaries "are negotiating now."

Iran has rejected a proposed truce in its war with the United States and Israel, insisting "on the need for a definitive end to the conflict," state news agency IRNA reported Monday.
