The United States secretly shipped hundreds of tons of uranium from Iraq to a customer in Canada on the request of Baghdad, a spokesman for the Pentagon has said.
About 550 metric tons of yellow cake uranium was moved to Baghdad's fortified Green Zone before being flown to a third country, where it was then shipped to Canada, Bryan Whitman said.
"The operation was completed over the weekend, on Saturday," Whitman said.
The uranium was found by US troops after the 2003 US invasion of Iraq at the Tuwaitha Nuclear Research Facility south of Baghdad.
It was placed under the control of the International Atomic Energy Agency (IAEA).
