In separate air force raids to target northern Gaza sites used to launch Kassam rockets at Israel, the air force bombed eight access routes in an attempt to hamper the movement of rocket cells to the area. The air strikes occurred before midnight Friday and early Saturday morning, and were in response to three Kassam rockets fired at Israel on Friday, including one that landed inside the compound of a strategic facility located in the industrial zone south of Ashkelon. The air sorties supplemented IDF artillery fire aimed at unpopulated northern Gaza areas on Friday. A plant worker was treated for shock and damage was caused to the strategic facility after a rocket exploded inside the compound. The industrial zone houses a number of key strategic facilities, including a major power plant, a desalination plant and oil pipelines. Two other rockets landed in and near Kibbutz Carmiya north of Gaza. One of the rockets landed in the kibbutz cemetery damaging a headstone of one of the graves. The Islamic Jihad claimed responsibility for the rocket attacks - Abu Hamza, an Islamic Jihad spokesman declared that plans were underway to fire a new improved rocket manufactured, that had a far greater distance capability and is able to cause greater damage on impact.
