The airstrikes hit two bridges, shops, a petrol station, cars, a gas locomotive, a truck carrying animal feed, shops, markets and homes. One of the strikes on a bridge killed IDPs as they were fleeing the area of Saada to take refuge in Amran, following the official announcement by the Saudi led coalition that Saada was a target and that civilians should leave the area.
The following report by the Legal Center for Rights and Development documents the crimes, and states that this was a poor residential area with no military camp located there.
The following videos recorded some of the damage in that area at that time. WARNING they include some graphic footage that you may find disturbing.
