The US, France, UK present evidence that Iran is hiding a functional uranium enrichment facility. Apparently Germany and Russia are on board too. Iran is facing an ultimatum from the G20 nations.
The IAEA is being asked for an comprehensive investigation of the secret underground facility that is being called an offensive facility and not one for peaceful use of nuclear energy. Iran has until October 1st to comply with IAEA inspections or face actions. Presumably this would start with immediate international sanctions but the possibility of military action was not dismissed.
