I think those pieces are more suitable for Use of chemical weapons in the Syrian civil war Here they seem to me like WP SYNTH considering they preceded the Ghouta attack and the U S said it ruled out rebel use of chemical weapons in the attack and I d note the U S is not friendly with Nusra which it has since targeted with airstrikes while del Ponte ended up apparently reversing her position anyway I can maybe see a case for mentioning the U S report on Nusra in the Capability section just as something like The United States Defense Intelligence Agency concluded in a June 2013 report that Jabhat al Nusra a hardline rebel group had been working toward developing a chemical weapons capability REF
