Live updates: Trump warns Iran will 'be living in Hell' in profanity-laced threat

The war between the U.S. and Iran entered its 37th day Sunday, with fighting ongoing despite President Donald Trump’s claim that Iran had been "completely decimated." 

More than 1,900 people have been killed in Iran, along with dozens more across the region, as the conflict continues to widen.

Tensions escalated this weekend after Trump issued a 48-hour ultimatum for Iran to "make a deal" or reopen the Strait of Hormuz, a key global oil route. Iranian officials warned that further attacks, especially on nuclear sites, could have catastrophic regional consequences, raising fears of a broader crisis.

8:57 a.m. ET: President Trump renewed his threats against Iran Sunday in a profanity-laced post on Truth Social, saying "you'll be living in Hell" if the Strait of Hormuz, a critical route for oil shipments, isn't reopened by Tuesday.

"Tuesday will be Power Plant Day, and Bridge Day, all wrapped up in one, in Iran," Trump wrote on Sunday. "There will be nothing like it!!! Open the [F***in'] Strait, you crazy bastards, or you'll be living in Hell – JUST WATCH! Praise be to Allah. President DONALD J. TRUMP."

 The United States said Sunday it rescued a service member missing behind enemy lines since Iran downed a fighter jet, as President Donald Trump escalated pressure on Tehran with a new looming deadline to reopen the Strait of Hormuz.

Trump wrote that the aviator is injured but "will be just fine," adding that he took refuge "in the treacherous mountains of Iran."

Trump said the rescue involved "dozens of aircraft" and that U.S. had been monitoring his location "24 hours a day, and diligently planning for his rescue."

A second crew member was rescued the day the aircraft was shot down. It was one of two military planes to go down on Friday.
