Jerusalem (CNN) -- There's a new distinction in the strife between Israel and Gaza-based armed groups -- Israel's portable anti-rocket system called the Iron Dome. With the ability to effectively take down mid-range rockets targeted at Israeli cities, and with a success rate of over 90%, the system is helping Israel offset the most widespread threat to its citizens in recent years, according to Israeli officials. Thirty-seven rockets fired out of Gaza towards Israeli cities have been intercepted since Friday, a spokesman for the Israel Defense Forces said Sunday. "I must point out that the Iron Dome system has proven itself very well and we will, of course, see to its expansion in the months and years ahead. We will do everything in our power to expand the deployment of this system," Israeli Prime Minister Benjamin Netanyahu said Sunday at his cabinet meeting.
