US and Iran trade threats to unleash 'hell' as search for US airman continues

US President Donald Trump threatened that "all hell would rain down on" Iran if a deal was not made, an ultimatum that Tehran rejected. In response, an Iranian military officer stated that "the gates of hell will open for you." Meanwhile, Iran intensified missile strikes on Gulf States, Iraq, and Israel as both countries searched for a missing American crew member after a US F-15 was shot down over Iran. Iranian officials have also offered bounties for the capture of the crew member.
