The Iranian military has damaged at least 20 U.S. military sites since the conflict started in February, the BBC reports, based on an analysis of images and videos.
According to the media outlet, Iran has targeted key facilities across eight countries in the Middle East, including Saudi Arabia, the UAE, Qatar, Kuwait, Iraq, Jordan, Bahrain, and Oman, "with some analysts placing the number of bases hit as high as 28."
In particular, Iranian attacks have damaged three Terminal High Altitude Area Defense (THAAD) batteries in the UAE and Jordan. Iranian strikes have also heavily hit U.S. refuelling and surveillance aircraft in Saudi Arabia.
The BBC points out that the extent of damage caused to U.S. facilities is difficult to quantify, but a May estimate by the Pentagon put the total cost of Operation Epic Fury at $29 billion, "with much of that likely to be spent on ‘repair or replacement costs for equipment’ destroyed in the conflict."
The report also found that at least 42 aircraft - including F-15 and F-35 fighter jets, 24 MQ-9 Reaper drones and an A-10 attack plane - have been destroyed or damaged since February.
A US defense official declined to comment on the findings, citing "operational security reasons," the news outlet notes.
