A siren alerted Jerusalem Saturday afternoon to incoming rockets from the Gaza Strip as four landed in Palestinian territory near Hebron in the southern West Bank, Bethlehem and the Jewish settlement bloc of Gush Etzion and Bethlehem. They landed on empty ground and caused no casualties or damage. The Palestinian Authority has asked Israel to provide its towns with siren equipment and Arabic translations of the IDF Home Command’s directives for safety procedures against rocket attack.
