The Hague-based OPCW said President Bashar al-Assad’s government had agreed to accept the mission and had promised to provide security in areas under its control.
The use in war of “asphyxiating, poisonous or other gases” – both of which can be produced by chlorine and ammonia – is banned by the Geneva Protocol, of which Syria is a signatory.
There is rising evidence that Syria has been using Chemical Warfare with many cases of Chlorine and Ammonia inhalation being reported.
The attacks are alleged to have happened around April the 11th and soil testing seems consistent with a Chemical Weapon. In addition? Since the weapon was dropped from helicopter, the belief is that pro-Assad forces were involved.
