The conflict showed no signs of abating on Sunday as multiple fronts escalated simultaneously. Israel announced a barrage of new strikes on western Iran, while the US Department of Defense released the names of six service members killed when a military refuelling aircraft crashed in Iraq.
Britain responded to Trump's call for allied support by announcing it is considering sending Royal Navy ships and mine-hunting drones to help reopen the Strait of Hormuz. Energy Secretary Ed Miliband confirmed ministers were in discussions with allies about the UK's potential contribution to securing the vital waterway.
Iran's government spokesperson Fatemeh Mohajerani revealed the scale of civilian damage, stating that US-Israeli strikes have hit more than 42,000 civilian sites across the country. Tehran also made the unusual claim that the US and Israel are manufacturing copycat versions of Iran's "Lucas" drones to frame it for regional attacks.
The conflict continued to spill beyond Iran's borders. Overnight Israeli attacks killed four people in Lebanon, while thousands took to the streets of Paris in one of more than 85 protests across France opposing military operations in Iran, Lebanon, and Palestine.
Security experts warned that the war is raising the risk of a terrorist attack on American soil to levels unseen since September 11, 2001. "Of course there's going to be retaliation," one expert told the Guardian. "It may be that this is what Trump's interested in."
Meanwhile, critics pointed to Trump's behavior as increasingly erratic for a wartime leader, noting he has spent time playing golf, posting old pictures on social media, and rehashing a feud with comedian Bill Maher while the death toll mounts.
