The U.S. is reportedly planning a lengthy bombing campaign against Iran-aligned militias in Iraq and Syria in response. A drone packed with explosives struck a remote U.S. outpost in Jordan. Last Sunday, killing three American soldiers and injuring dozens more. The strike marked the first time that American lives were lost after months of attacks on U.S. bases in the region by various militant groups working in solidarity with Hamas. U.S. analysts concluded that the drone was of Iranian origin after analyzing fragments from the blast site. The officials told Reuters without giving any further information about the precise model. The White House has already blamed the attack on members of the Islamic Resistance and umbrella group of Iranian-armed militias operating across Iraq and Syria. U.S. President Joe Biden, however, said on Tuesday that he holds Tehran responsible in the sense that they're supplying the weapons to the people who did it. Asked about the Reuters report, U.S. Defense Secretary Lloyd Austin said that the Pentagon was still doing the forensics on the drone, adding that most of the drones that are in the region have a connection with Iran.
