And there is no news that Saudis prevented part of the attack or even were able to detect the drones. When the first news broke out in the morning today everyone was unsure if that's a local accident or something else.
Its american anti missile systems are there, but has been proven useless in this attack. The low flying small sized drones aren't detectable on radar. There were 10 involved and most of all struck their targets. These are cheap and have possibly flown a thousand kilometers deep inside Saudi.
Imagine the chaos that will ensue if they start using those against more vulnerable targets.
Saudis by now should be feeling like sitting duck.
