The “Convention on Prohibitions or Restrictions on the Use of Certain Conventional Weapons which may Be Deemed to be Excessively Injurious or to Have Indiscriminate Effects” entered into force on 2 December 1983, six months after twenty States had deposited their instruments of ratification, acceptance, approval or accession. The three Protocols annexed to the Convention also entered into force on that date; Protocol I prohibits the use of weapons with non-detectable fragments, Protocol II prohibits or limits the use of mines, booby-traps and other devices, and Protocol III prohibits or limits the use of incendiary weapons.
