US President Donald Trump said Saturday he was going to review a new Iranian peace proposal but cast doubt over its prospects, as a senior military officer in Tehran indicated renewed fighting was "likely."
The dour outlook came after Iran's Tasnim and Fars news agencies said Tehran had submitted a 14-point proposal to mediator Pakistan. Details included ending the conflict on all fronts and enacting a new framework for the crucial Strait of Hormuz, Tasnim said.
"I will soon be reviewing the plan that Iran has just sent to us, but can't imagine that it would be acceptable in that they have not yet paid a big enough price for what they have done to Humanity, and the World, over the last 47 years," Trump said on his Truth Social platform.
In a brief interview with reporters in West Palm Beach, Florida, he declined to specify what could trigger new military action against Iran.
"If they misbehave, if they do something bad, but right now, we'll see," he said. "But it's a possibility that could happen, certainly."
The war, launched by the United States and Israel in late February, has been on hold since April 8, with one failed round of peace talks having taken place in Pakistan.
On Saturday, Mohammad Jafar Asadi, a senior figure in the Iranian military's central command, said "a renewed conflict between Iran and the United States is likely."
"Evidence has shown that the United States is not committed to any promises or agreements," he added, according to Fars news agency.
Deputy foreign minister Kazem Gharibabadi told diplomats in Tehran "the ball is in the United States' court to choose the path of diplomacy or the continuation of a confrontational approach."
Iran, he said, was "prepared for both paths."
US news site Axios reported earlier in the week that Trump's envoy Steve Witkoff had asked for Tehran's nuclear program to be put back on the negotiating table.
Iran's mission to the UN pointed to the massive US nuclear arsenal, accusing Washington on Saturday of "hypocritical behavior" towards Iran's own atomic ambitions.
There was no legal "restriction on the level of uranium enrichment, so long as it is conducted under the IAEA's supervision, as was the case with Iran," it said, using the abbreviation for the UN nuclear watchdog.
Iran has maintained a stranglehold on the Strait of Hormuz since the war began, choking off major flows of oil, gas and fertilizer to the world economy, while the United States has imposed a counter-blockade on Iranian ports.
Oil prices are about 50 percent above pre-war levels.
The vice speaker of Iran's parliament, Ali Nikzad, said that under draft legislation being considered for managing the waterway, 30 percent of tolls collected would go towards military infrastructure, with the rest earmarked for "economic development."
"Managing the Strait of Hormuz is more important than acquiring nuclear weapons," he said.
