Hamas has refused to allow the supplies from the flotilla ships into the Gaza Strip and has accused Israel of tampering with the equipment.
Israel has loaded 20 trucks with the cargo from the aid ships, including clothing, medical supplies and blankets, to bring into the area.
But Hamas, which controls the Gaza Strip, is apparently preventing its delivery.
A Hamas spokesperson said they would only accept the transfer of the humanitarian supplies when all the pro-Palestinian activists detained by Israel were released.
Ahmed Kurd, Hamas Minister for Social Welfare also accused Israel of removing the batteries from wheelchairs so that they could not be used.
