Four Arabs infiltrated into northern Israel from Lebanon last night, opening fire at army forces patrolling the border. The troops returned fire, presumably hitting some of the infiltrators. Northern area communities remain on high alert… An Israeli passenger bus was targeted by gunfire earlier today at the Ziff Junction in the Southern Hevron Hills area. The armor-plated bus was hit by the gunfire but the bullets were unable to penetrate the protective coating…Soldiers in the Netzarim area of Gush Katif are at this time involved in a battle with Arab gunmen. No injuries have been reported in any of these incidents.
