An Iranian missile slammed into the main hospital in southern Israel early Thursday, wounding people and causing "extensive damage," according to the medical facility. Israeli media aired footage of blown-out windows and heavy black smoke.

The Arrow system intercepts long-range missiles at higher altitudes; the David’s Sling system intercepts them at lower altitudes; while the Iron Dome takes out shorter-range rockets, usually fired from Gaza, or the fragments of missiles already intercepted by other defense systems.
