Possible Mustard Release at Ukhaydir

Ammunition Storage Depot

Case Narratives are reports of what we know today about certain events of the 1990-1991 Gulf War. This particular case narrative focuses on a possible chemical agent release resulting from Coalition bombings of the Ukhaydir Ammunition Storage Depot. This is an interim, not a final, report. We hope that you will read this and contact us with any information that would help us better understand the events reported here. With your help, we will be able to report more accurately on the events surrounding incidents reported in this narrative. Please contact my office to report any new information by calling:

Special Assistant for Gulf War Illnesses
Department of Defense


Last Update: June 16, 2000

Many veterans of the Gulf War have expressed concern that their unexplained illnesses may result from their experiences in that war. In response to veterans’ concerns, the Department of Defense established a task force in June 1995 to investigate incidents and circumstances relating to possible causes. The Office of the Special Assistant to the Deputy Secretary of Defense for Gulf War Illnesses assumed responsibility for these investigations on November 12, 1996, and has continued to investigate reports of chemical warfare agent incidents.

To inform the public about the progress of these efforts, the Department of Defense is publishing on the Internet and elsewhere accounts that may contribute to the discussion of possible causes of illnesses of Gulf War veterans, along with documentary evidence or personal testimony used in compiling the accounts. This narrative is such an account.
