Practice Relating to Rule 84. The Protection of Civilians and Civilian Objects from the Effects of Incendiary Weapons
In 2005, in reply to a question concerning the use of chemical weapons by US armed forces in Iraq, the Italian Under-Secretary of State for Defence stated:
[A]s regards the field of conventional weapons, the definition of incendiary weapons adopted by the Third Protocol to the Convention of 1980, […] not yet ratified by the United States, on Prohibitions or Restrictions on the Use of Certain Conventional Weapons Which May be Deemed to be Excessively Injurious or to Have Indiscriminate Effects (Carrying Concealed Weapons), does not seem to include ammunition having incendiary effects only in accidental ways, as for example flaring, tracing, smoke-making or signalling systems.

In 2006, in reply to a question concerning the use of white-phosphorous weapons in Iraq, the Italian Under-Secretary of State to the Presidency of the Council of Ministers stated:
As concerns the area of conventional weapons, the definition of “incendiary weapons” adopted by Additional Protocol III to the 1980 Convention on prohibitions and restrictions on the use of conventional weapons whose effects could be indiscriminate or excessively toxic (carrying concealed weapons) … does not seem to include ammunition having only incidental incendiary effects such as, for instance, illuminants, tracers, smoke or signalling systems.
