The Niger uranium forgeries were forged documents initially released by SISMI (Italian military intelligence), which seem to depict an attempt made by Saddam Hussein in Iraq to purchase yellowcake uranium powder from Niger during the Iraq disarmament crisis. On the basis of these documents and other indicators, the governments of the United States and the United Kingdom asserted that Iraq violated United Nations Iraq sanctions by attempting to procure nuclear material for the purpose of creating weapons of mass destruction.
The first report of these documents was in a Central Intelligence Agency (CIA) Senior Executive Intelligence brief dated 18 October 2001, entitled: "Iraq: Nuclear Related Procurement Efforts." This information was not considered to be certain and not much was done to promote this claim right away.
These documents were sent to the CIA office in Rome by SISMI.
On 10 May 2002, the CIA's Office of Near Eastern and South Asian Analysis (NESA) in the Directorate of Intelligence (DI) prepared a Principals Committee briefing book updating the status of Iraqi weapons of mass destruction (WMD) programs. The document noted that a "foreign government service says Iraq was trying to acquire 500 tons of uranium from Niger."
On 22 July 2002, the United States Department of Energy (DOE) published an intelligence product (Daily Intelligence Highlight, Nuclear Reconstitution Efforts Underway?) which highlighted the intelligence on the Iraq-Niger uranium deal as one of three indications that Iraq might be reconstituting its nuclear program.
There was a second and third dissemination of these forged documents to the USA by SISMI in early September 2002. One source was a suspicious "ex-agent," of SISMI who occasionally worked on and off for them, who was selling the documents.
