MK Arieh Eldad (Hatikva-National Union) demanded on Friday that Defense Minister Ehud Barak face trial for aiding an enemy during wartime, after the latter authorized the opening of the Gaza Strip border crossings on Friday morning to allow the transfer of humanitarian aid into the impoverished territory.

Eldad urged Attorney General Menachem Mazuz to indict Barak, in a message saying "the media reported that the defense minister allowed dozens of trucks carrying supplies to enter Gaza, while western Negev communities are being continuously fired upon from the Strip. This is precisely the definition of aiding an enemy during wartime, and he who does so must be brought to justice."

Meanwhile Friday, Israel renewed its transfer of humanitarian aid into the Gaza Strip, despite military preparations for a for a large-scale campaign against the Gaza militants.

The army said the first of approximately 90 trucks had started to deliver medicine, fuel, cooking gas and other vital goods into Gaza. The shipment includes a large donation of goods from Egyptian President Hosni Mubarak's wife.

Cabinet Minister Benjamin Ben-Eliezer said the humanitarian shipment was meant to be a message to the people of Gaza that they were not Israel's enemy.

"We are sending them a message that the Hamas leadership has turned them into a punching bag for everyone," Ben-Eliezer told Israel Radio. "It is a leadership that has turned school yards in rocket launching pads. This is a leadership that does not care that the blood of its people will run in the streets."

Israel's Defense Ministry agreed to open its cargo crossings into Gaza as part of its policy of avoiding a humanitarian crisis there. Barak said the decision came after consultations with defense officials as well as calls from the international community.

Israel had originally agreed to open the cargo crossings with Gaza on Wednesday, but shut the passages when Gaza militants began pummeling southern Israeli towns with more than 80 rockets and mortars on Wednesday. The barrage was the heaviest since before an Egyptian-mediated six-month-long truce between Israel and Gaza's Hamas rulers took effect in June.

Israel has maintained a strict blockade of Gaza since the June 19 cease-fire began unraveling six weeks ago, allowing in only small quantities of essential goods. Egypt has also sealed its border crossing with the territory, which is Gaza's main gateway to the outside world.
