Syrian doctors to show the US evidence of Assad’s use of chemical weapons

"Recent reports suggest that militant forces in Syria, including Isis, are developing a chemical weapons capability of their own."
My apologies if this has already been pointed out, but it is a libel on the Syrian rebel groups fighting Assad that they have done any such thing, just as it was a lie two years ago when it was claimed that such rebel groups attacked themselves with sarin. This libel should not be reproduced in a respectable newspaper.
