35. Iraqi Terrorists Used Mustard Gas Against US Soldiers in Baghdad, 2006: 2 Wounded
For American soldiers deployed to Iraq, the most imminent danger was often IEDs. They were frequently not only hidden from view but also undetectable. No one had any idea of the threat until the device had already exploded and caused injuries or even fatalities.
In Baghdad in 2006, terrorists constructed an IED that was filled with mustard gas. The mustard gas was inside chemical weapon artillery shells, which may have been leftover from when the CIA armed Iraqi forces in the 1980s in the Iran-Iraq War. Two soldiers were injured in the attack.
