Syrians using Chemical Weapons in Darfur?

The Channel News reports that Syria might have tested chemical weapons on Darfur refugees in agreement with the Sudanese government (hat tip: Andrew Sullivan).

"According to [The German Newspaper] Die Welt, the Syrians had suggested close cooperation on developing chemical weapons, and it was proposed that the arms be tested on the rebel SPLA, the Sudan People's Liberation Army, in the south.

But given that the rebels were involved in peace talks, the newspaper continued, the Sudanese government proposed testing the arms on people in Darfur."

The article claims that "injuries apparently caused by chemical arms were found on the bodies of the victims." So far, the mainstream media hasn't picked this up, and I have no idea how much credibility the story has. But if it's true, it provides a deadly accent to the need for immediate US and global intervention in Darfur.
