II restricts landmines, booby traps Protocol III restricts incendiary weapons Protocol IV restricts blinding laser weapons (adopted on October 13, 1995, in Vienna) Protocol V sets out obligations and best practice for the clearance of explosive remnants of war, adopted on November 28, 2003, in Geneva Protocol II was amended in 1996 (extending its scope of application), and entered in force on December 3, 1998. The amendment extended the restrictions on landmine use to internal conflicts; established reliability standards for remotely delivered mines; and prohibited the use of non-detectable fragments in anti-personnel landmines (APL). The failure to agree to a total ban on landmines led to the Ottawa Treaty. Protocol I: Non-Detectable Fragments Protocol I on Non-Detectable Fragments prohibits the use of any weapon the primary effect of which is to injure by fragments which are not detectable in the human body by X-rays. The reason is that such fragments are difficult to remove and cause unnecessary suffering. The protocol applies when the "primary effect" is to injure by non-detectable fragments and does not prohibit all use of e.g. plastic in weapons design. Protocol II: Mines, Booby Traps and Other Devices Protocol II on Prohibitions or Restrictions on the Use of Mines, Booby-Traps and Other Devices was amended on May 3, 1996, to strengthen its provisions and extend the scope of application to cover both international and internal armed conflicts. The protocol regulates, but does not ban, land mines. It prohibits the use of non-detectable anti-personnel mines and their transfer; prohibits the use of non-self-destructing and non-self-deactivating mines outside fenced, monitored and marked areas; prohibits directing mines and booby traps against civilians; requires parties to the conflict to remove mines and booby traps when the conflict ends; broadens obligations of protecting peacekeeping and other missions of the United Nations and its agencies; requires States to enforce compliance with its provisions within their jurisdiction; and calls for penal sanctions in case of violation. Protocol III: Incendiary Weapons Protocol III on Prohibitions or Restrictions on the Use of Incendiary Weapons prohibits, in all circumstances, making the civilian population as such, individual civilians or civilian objects, the object of attack by any weapon or munition which is primarily designed to set fire to objects or to cause burn injury to persons through the action of flame, heat or a combination thereof, produced by a chemical reaction of a substance delivered on the target.
