The Muqata: Here is a video of the newly operation Iron Dome anti-missile defense system in Israel in action. What you will see is a
Kassam Grad missile flying towards Ashkelon. Within a second of launch the “Red Alert” siren goes off in Ashkelon and surrounding communities. The Iron Dome system tracks the Kassam Grad rocket and launches a countermeasure rocket. You then see the Kassam explode in mid-air and Ashkelon is safe.
