Evidence points to Iranian missiles accurately hitting Saudi sites
Imagery of the impact sites at Abqaiq show most targets were hit from due west by missiles, as opposed to the explosive charges typically carried by Houthi drones. The calibre of the missiles was relatively small, with a warhead probably much less than 200kg. Much of the damage caused was due to secondary fires and explosions, with combustible targets in the complex presumably selected for this purpose. The missiles had point-of-impact effects not dissimilar to that caused by ground launched anti-tank missiles.
