No proof of iran did that and the only reason they don't believe Yemen army did it is WOW factor . well less than a decade ago they somehow felt the same WOW factor for us.Here’s the background: In the early hours of Sept. 14, the Iranian Air Force launched roughly 20 drones and cruise missiles at one of Saudi Arabia’s most important oil fields and processing facilities. The drones and cruise missiles flew so low and with such stealth that neither their takeoff nor their impending attack was detected in time by Saudi or U.S. radar. The pro-Iranian Houthi militia in Yemen claimed responsibility for the raid. That was as believable as saying that Santa Claus did it.
