Just in case you needed another example of how dangerous the Iraq war has made this world, here you go. In Iraq pre -91, there was a facility known as Muthanna. Shortly after the 91 invasion, it was placed under U.N. control. Everything in the facility was catalogued and monitored. When UNMOVIC went back in, they made sure that nothing in that facility had been moved while they were gone (It had not). This location held roughly 2500 old sarin-filled rockets, which the UN had sealed in a bunker surrounded by concrete and brick instead of taking the risk of destroying the stuff.
Guess what the Duelfer report tells us about this site? You guessed it. Looted. They don't know for certain whether or not anything important/chemical in nature was taken, but the actual concrete bunkers that contained the old chemical shells were broken into.
Charles Duelfer's arms teams say all U.N.-sealed structures at the Muthanna site were broken into. If the so-called Bunker 2 was breached and looted, it would be the second recent case of restricted weapons at risk of falling into militants' hands.
