The conflict in Syria is just that, "baddies vs baddies"; foreign radical Islamist terrorists/militants against the Al Assad Government. Professional mercenaries are now pouring into Syria and having a high season. Passports of the dead show that many have come from Libya, Egypt, Saudi Arabia, Qatar, Chechnia, Turkey and even France or the UK.
Those who are trying to implicate the Syrian government as being behind the use of chemical weapons are seriously misguided. It defies common sense to suggest that Syrian soldiers would use chemical weapons against civilians. Rather, it is certainly more plausible that it was most likely an effort of the FSA who, among the other horrendous atrocities they have committed over the last two years (be-headings, pointblank executions, testing of chemical weapons on bunny rabbits etc) , are trying to pull western powers into a war that they are losing.
