From MSNBC today. Jim Miklaszewski reporting:

Following up on that story from last night, military officials tell NBC News that on April 10, 2003, when the Second Brigade of the 101st Airborne entered the Al QaQaa weapons facility south of Baghdad, that those troops were actually on their way to Baghdad, that they were not actively involved in the search for any weapons, including the high explosives, H.M.X. and R.D.X. The troops did observe stock piles of conventional weapons but no H.M.X. or R.D.X. and because the Al Qaqaa facility is so huge, it's not clear that those troops from the 101st were actually anywhere near the bunkers that reportedly contained the H.M.X. and R.D.X. Three months earlier, during an inspection of the Al Qaqaa compound, the International Atomic Energy Agency secured and sealed 350 metric tons of H.M.X. and R.D.X. Then in March shortly before the war began, the I.A.E.A. conducted another inspection and found that the H.M.X. stockpile was still intact and still under seal. But inspectors were unable to inspect the R.D.X. stockpile and could not verify that the R.D.X. was still at the compound. Pentagon officials say elements of the 101st airborne did conduct a thorough search of several facilities around the Al QaQaa compound for several weeks during the month of April in search of W.M.D. They found no W.M.D. And Pentagon officials say it's not clear at that time whether those other elements of the 101st actually searched the Al QaQaa compound. Now, Pentagon officials say U.S. troops and members of the Iraq Survey Group did arrive at the Al QaQaa compound on May 27. And when they did, they found no H.M.X. or R.D.X. or any other weapons under seal at the time. Now, the Iraqi government is officially said that the high explosives were stolen by looters. Pentagon officials claim it's possible -- they're not sure, they say, but it's possible that Saddam Hussein himself ordered that these high explosives be removed and hidden before the war. What is clear is that the 350 metric tons of high explosives are still missing, and that the U.S. or Iraqi governments or international inspectors for that matter cannot say with any certainty where they are today.
