Translate the following English sentence to French:
"Therefore, given the scale of the crime that has been committed against whole civilian populations, it is crucial that we investigate, try and convict the leaders responsible for this crime against humanity, and immediately ban the manufacture, testing, use and sale of this type of weapon containing depleted uranium, not simply approve a moratorium."
Ainsi, face à la dimension du crime commis contre des populations civiles entières, il est urgent d'enquêter, d'évaluer et de condamner les hauts responsables de cet acte criminel contre l'humanité et interdire immédiatement la fabrication, les essais, l'utilisation et la vente de ce type d'armes à l'uranium appauvri ; il ne faut pas se contenter d'approuver un moratoire.
