U.N. agency confirms 377 tons of explosives have vanished

Several hundred tons of conventional explosives were looted from a former Iraqi military facility that once played a key role in Saddam Hussein's efforts to build a nuclear bomb, the U.N. nuclear agency told the Security Council on Monday.

A "lack of security" resulted in the loss of 377 tons of high explosives from the sprawling Al-Qaqaa military installation about 30 miles south of Baghdad, said Mohamed ElBaradei, head of the International Atomic Energy Agency, or IAEA.

...The letter informed the IAEA that since Sept. 4, 2003, looting at the Al-Qaqaa installation south of Baghdad had resulted in the loss of 214.67 tons of HMX, 155.68 tons of RDX and 6.39 tons of PETN explosives.

HMX and RDX can be used to demolish buildings, down jetliners, produce warheads for missiles and detonate nuclear weapons. HMX and RDX are key ingredients in plastic explosives, such as C-4 and Semtex -- substances so powerful that Libyan terrorists needed just 1 pound to blow up Pan Am Flight 103 over Lockerbie, Scotland, in 1988, killing 170 people.

ElBaradei's cover letter to the council said that the HMX had been under IAEA seal and that the RDX and PETN were "both subject to regular monitoring of stock levels."

"The presence of these amounts was verified by the IAEA in January 2003," he said.

At the Pentagon, an official who monitors developments in Iraq said U.S.-led coalition troops had searched Al-Qaqaa in the immediate aftermath of the March 2003 invasion and confirmed that the explosives, which had been under IAEA seal since 1991, were intact. The site was not secured by U.S. forces, the official said, speaking on condition of anonymity.
