US president Donald Trump said that “many of Iran’s military leaders” had been “terminated” in what he described as a massive strike in Tehran, sharing video footage showing explosions in the city.However, he did not provide further details about the strike or specify its targets.Trump had earlier warned that “all hell would rain down on” Iran if it failed to reach a deal, drawing a similarly strong response from Tehran.An Iranian military spokesperson said the entire region would turn into “hell” if the United States and Israel continued to escalate the conflict.On Saturday, Iran launched another round of missile attacks targeting the Gulf states, Iraq and Israel, with debris from intercepted missiles causing damage.Meanwhile, US and Iranian forces are searching for a missing American crew member after a US F-15 fighter jet was shot down over southern Iran on Friday. US media reported that the pilot has since been rescued.Iranian authorities have urged citizens to find the American “alive”, offering rewards for his capture.A US A-10 Warthog aircraft involved in the search-and-rescue mission for the downed jet was also hit and damaged, although its pilot was safely rescued.Last week, Trump announced a 10-day pause on attacks on energy facilities to allow Iran time to “make a deal.”The war began with joint US-Israel strikes on February 28 and has since killed thousands, rattled global markets, disrupted key shipping routes and driven up fuel prices.Both sides have threatened and carried out attacks on civilian targets, prompting warnings of possible war crimes.
