Le Monde on Witnessing Chemical Weapons; NPR on Whether Rebels Could Be Responsible

As we wait for the US to provide evidence that the Asad regime is responsible for the use of chemicals in Syria, here's an eyewitness report from Le Monde that claims to have witnessed such a use.

That seems to be fairly conclusive, and most have dismissed Syrian government claims that it was the rebels who used the weapons. But to give the Devil's Advocate an argument, NPR addresses the question "Is it Possible the Syrian Rebels (Not Assad) Used Chemical Weapons?"  I'm not endorsing the idea, merely pointing to the article.
