The US military first launched attacks against the Houthis in 2023, during the Biden administration, after the militants started launching drones and missiles at commercial ships in the Red Sea.
Multiple munitions pummeled the compound, striking at least five buildings, according to an AP analysis of satellite imagery. Hundreds of pounds of explosives collapsed the school.
The 10 entities include Aveox, which holds aerospace defence contracts with the US military, and Oshkosh Defense, which produces military vehicle fleets.
Pentagon spokesman Sean Parnell said in a statement that the building's safety systems "have detected an air quality issue necessitating precautionary measures until we determine its significance."
