The Day of Remembrance for all Victims of Chemical Warfare is an annual event held on April 29 as a “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.” It is officially recognised by the United Nations (UN) and has been celebrated since 2005. On the 2013 observance day, the UN Secretary-General Ban Ki-moon gave a speech where he stated:
On this Remembrance Day, I urge the international community to intensify efforts to rid the world of chemical weapons, along with all other weapons of mass destruction. Let us work together to bring all States under the Convention and promote its full implementation. This is how we can best honour past victims and liberate future generations from the threat of chemical weapons.
