Sarin gas confirmed in Baghdad roadside bomb

Comprehensive testing has confirmed the presence of the chemical weapon sarin in the remains of a roadside bomb discovered this month in Baghdad, US government officials said.

The determination, made by a laboratory in the US that officials would not identify, verifies what earlier, less-thorough field tests had found: the bomb was made from an artillery shell designed to disperse the deadly nerve agent on the battlefield, the two officials said yesterday.
