Occupied Jerusalem, November 21 (QNA) - Israel's decision to keep the crossings into Gaza closed will remain in effect until the end of the week, defense officials have said despite an official IDF assessment submitted to Defense Minister Ehud Barak that the restriction is not having an effect on Hamas. The crossings between Israel and Gaza have been closed for almost two weeks as part of Israel's response to the continued rocket attacks against the western Negev. On Wednesday, two Kassam rockets landed south of Ashkelon without causing any injuries or damage. On Tuesday, three rockets slammed into fields in the Negev. Officials in Barak's office said Wednesday that the closure imposed on the crossings would remain in effect even though its effectiveness was minimal. (QNA)
