The crime committed by saddam Hussain when he used chemical and bacteriological weapons is not justified at all niether in Koran nor by muslims. This is a berbarian action and whoever use the same practise or similar such as phospheric and others is absouletly the same. the Koran doesn't mention clearly by word not to use nuclear or chemical weapons, but there are so many scipture forbidden to hurt the innocent and who does will be rewarded by endless punishment and hell.
