JERUSALEM (AP) — In four days of fighting against Gaza-based militants, Israel has used a missile-defense system called "Iron Dome" to intercept rockets fired at populated civilian areas. It says the new home-grown system has been a tremendous success. As of Saturday evening, the military said it had shot down some 240 incoming rockets, more than half the number of projectiles launched into Israel since Wednesday.
Here's a quick look at the system:
—Produced by Israeli-based Rafael Advanced Defense Systems, Iron Dome is meant to shoot down rockets and artillery shells with ranges of up to 70 kilometers, or 45 miles. It has been operational since 2011. Officials say it has a roughly 80 percent success rate.
—How it works: The system detects launches of rockets and quickly determines their flight path. If it is headed toward populated areas or sensitive targets, it fires an interceptor with a special warhead that strikes the incoming rocket within seconds. Rockets headed toward open areas area allowed to land.
—Currently, five Iron Dome batteries are deployed in Israel. Most are located in the south near Gaza. A fifth battery was deployed outside Tel Aviv on Saturday, two months ahead of schedule. Hours later, it shot down a rocket headed toward Tel Aviv.
