Israeli Arabs threw stones at soldiers staffing the Iron Dome missile defense batteries in the north on Wednesday. Police were called to the scene and arrested a 14-year-old from a village nearby.

Two anti-missile systems were stationed in the north of the country in late January and a third one was deployed on Tuesday, apparently as a precautionary measure in light of the increasingly volatile situation in Syria.

The soldiers operating the Iron Dome told the NRG news site that some local Arab residents cursed them from time to time, but this was the first time stone were thrown at them. There were no injuries in the incident.

Designed to thwart incoming short-range missiles, the Iron Dome system proved highly effective during Israel’s Operation Pillar of Defense against terror targets in Gaza. Some 1,500 rockets were fired at Israel during the eight-day operation, and Iron Dome intercepting 84 percent of the rockets that were heading toward residential areas in Israel’s south and center.
