Two Kassam rockets were launched from the Gaza Strip into Israel overnight Saturday, Israel Radio reported. The rockets exploded in open areas in the western Negev. There were no reports of casualties or damage. 'Color Red' warning sirens were heard in Sderot following the launch. There was no report of an Israeli response as of yet. Prime Minister Binyamin Netenyahu has vowed to respond to any attack from the Gaza Strip and has so far been true to his word.
