TEHRAN, April 7 -- Iran on Monday rejected a 45-day ceasefire proposal and said it wants a permanent end to the war, while President Donald Trump appeared to widen his threat from civilian targets to the whole Islamic Republic as his ultimatum ticked closer. "The entire country can be taken out in one night, and that night might be tomorrow night," Trump told a news conference at the White House. He has called his Tuesday 8pm ET (Wednesday, 5.30am IST) deadline for Iran to make a deal final. The US stepped up threats against Iran to open the Strait of Hormuz or face a barrage of attacks on civilian targets. "Today will be the largest volume of strikes since day one," Defense Secretary Pete Hegseth said. "Tomorrow, even more than today." Israel piled on pressure by attacking a major gas field that is Iran's biggest source of domestic energy. Tehran conveyed its 10-point response through Pakistan, a key mediator, including proposals on reconstruction and the lifting of sanctions, Iran's state-run IRNA news agency said. Trump cast Iran's recent proposals as a "very significant step" but not enough to end the fighting. "We only accept an end of the war with guarantees that we won't be attacked again," Mojtaba Ferdousi Pour, head of Iran's diplomatic mission in Cairo, told The Associated Press. He said Iran no longer trusts the Trump administration after the US bombed the Islamic Republic twice during previous rounds of talks. And yet a regional official involved in talks said efforts had not collapsed. "We are still talking to both sides," he said, speaking on condition of anonymity to discuss closed-door diplomacy. Trump claimed the US had an active and willing participant on the other side in talks with Iran, adding that Tehran would like to make a deal. He also told reporters that he thought the Iranian people should rise up against the government in the country if a ceasefire were declared. He also said reopening the Strait of Hormuz was a "big priority." Iranian and Omani officials were working on a mechanism for administrating the strait, through which a fifth of the world's oil is shipped in peacetime. Iran's grip on it has shaken the world economy. Tehran has refused to let US and Israeli vessels through after they started the war on Feb. 28. Israel struck a key petrochemical plant in the South Pars natural gas field and killed two paramilitary Revolutionary Guard commanders....
