“Now there is an analysis. I will not talk about the air defense systems of Saudi Arabia, except that it is being seriously studied, ”RIA Novosti quoted Hoffman as saying.

According to him, air defense systems all over the world "work with varying success."

On September 14, in Saudi Arabia, drones attacked two oil refineries owned by the state-owned company Saudi Aramco, after which fires occurred on them.
