A month ago, the US Center for Strategic and International Studies (CSIS) released a video about the possibility of an Iranian attack on Saudi oil facilities.
In that video, specifically the Baqiq (Abiqiq) oil complex as well as the Ras al-Tawana facility are two of the major targets whose attack could have a significant impact on the world economy and oil prices.
Part of the video shows exactly the repositories now targeted. Referring to the geographic location, the analyst says that if enough missiles are fired at the facility, no defense system will be able to defend it.
