The Conference of the States Parties at its Tenth Session decided that a memorial Day of Remembrance for all Victims of Chemical Warfare would be observed on 29 April each year — the date in 1997 on which the Chemical Weapons Convention entered into force.
This commemoration provides an opportunity to pay tribute to the victims of chemical warfare, as well as to reaffirm the commitment of the Organization for the Prohibition of Chemical Weapons (OPCW) to the elimination of the threat of chemical weapons, thereby promoting the goals of peace, security, and multilateralism.
In his 2014 message, Secretary-General Ban Ki-Moon said that “the horrific use of chemical weapons in the Syrian Arab Republic in 2013 casts a shadow over this year’s commemoration. I cannot forget the deeply shocking images I saw. The use of chemical weapons in Syria was a deplorable offense against humanity.”
