Trump said Iran could be "taken out in one night," which "might" be Tuesday - a deadline he set for Iran to reopen Hormuz, CNN reported. He reiterated threats to hit all of Iran's bridges and power plants.

Trump earlier Monday called a proposal drafted by countries working to implement a 45-day ceasefire a "significant step" but "not good enough," the news report said. Iran rejected the proposal and called for a permanent end to the war, CNN cited Iranian state-run media.
