using improvised explosive devices made from military munitions, most often 122 mm artillery shells and landmines. IEDs made with high explosives are far more powerful and devastating and have been used in some of the most damaging attacks carried out in Iraq, such as the August 19, 2003 suicide attack on the U.N. headquarters, and the March 17, 2004 attack on the Mount Lebanon Hotel, both in Baghdad. It is not clear whether these attacks were mounted using explosives from Al Qa'qaa. However, on October 28, 2004 a video was released by a group calling itself "Al-Islam's Army Brigades, Al-Karar Brigade" in which a masked man claimed that "the American intelligence" had helped them to obtain a "huge amount of the explosives that were in the Al Qa'qaa facility" and that the explosives would be "use[d] against the occupation forces and those who cooperate with them in the event of these forces threatening any Iraqi city." And a December 2003 report from a joint Defense Department intelligence task force concluded that the insurgents in Iraq "retain access to virtually all the weapons systems and ordnances previously controlled by the Iraqi military, security and intelligence assets. Unsecured arms depots and storage sites, in addition to open and black market availability of weapons and ammunition, eliminate the need for the [insurgents] to maintain a formidable arsenal." Montgomery McFate of the Human Terrain Team program noted in 2005: The high explosives The high explosives were stored under the supervision of the United Nations due to their sensitive nature and dual use in WMDs. According to the IAEA, there were 340 tonnes consisting of: 194.741 tonnes of HMX, 141.233 tonnes of RDX, and 5.800 tonnes of PETN. These explosives were stored in solid crystalline form and could be used to make powerful plastic explosives, are safe to transport and do not detonate on impact. The total quantity, 341.744 tonnes (753,417 pounds), would require approximately 40 large trucks to convey. Chemical weapons equipment In addition to the explosives, al Qa'qaa held some of the remnants of Iraq's chemical warfare program from the early 1990s, "including 800 pieces of chemical equipment." The areas that had been involved in chemical processing were "wrecked by fire and possible extensive looting" after the invasion; as The New York Times reported, "Unknown is the fate of such equipment there like separators, heat exchangers, mixers and chemical reactors, all of which
