26 May 2004 -- U.S. officials say testing has confirmed that an artillery shell detonated in Iraq recently contained the deadly nerve agent sarin.
The U.S. military said last week that American troops had discovered the shell, which had been rigged into a roadside bomb. The 155-millimeter round exploded, releasing what was believed to be a small of sarin.
The round is believed to date from before the 1991 Gulf War. U.S. officials said it is unclear whether the attackers who used the shell for the roadside bomb knew it contained sarin.
It is the first time any chemical weapon has been found in Iraq since the U.S.-led invasion in March 2003.
