Iran has sent its response to the latest U.S. ceasefire proposal via Pakistani mediators, but U.S. President Donald Trump quickly rejected it as “TOTALLY UNACCEPTABLE!”, offering no details. Sunday's development is the latest setback to resolve the standoff in the Persian Gulf that has throttled shipping and sent energy prices soaring. Iran's state media said that Tehran rejected the proposal from the United States as amounting to surrender, insisting instead on “war reparations by the U.S, full Iranian sovereignty over the Strait of Hormuz, an end to sanctions, and the release of seized Iranian assets.”
