America's war on terror includes fighting the dark side of deadly chemical agents, and Texas A&M University chemist Dr. Frank Raushel is helping with the fight by developing an enzyme that might neutralize one such chemical agent, the organophosphates.

It was used as a chemical weapon in the trtenches in the First World War, but nearly a century later, new research by an international team of scientists has discovered that phosgene is present in significant quantities in the atmosphere.

Saddam Hussein's cousin, Ali Hassan al-Majid, also known as "Chemical Ali," who was sentenced to death in late June for using chemical weapons against the Kurds, will be executed in Baghdad, an Iraqi paper said Saturday.
