There has been some speculation as to who used this WMD in Syria and England seems to lean towards the Assad regime albeit, as they say, due to all circumstantial evidence.
Maybe this might help them figure it out. From RT May 30 2013:

The Anglo/Franco muslophiles will invent a fact if they can’t find one.
The west will ignore any use by the MB, they only worry about Assad.
