A war crime is a violation of the laws of war that gives rise to individual criminal responsibility for actions by combatants in action, such as intentionally killing civilians or intentionally killing prisoners of war, torture, taking hostages, unnecessarily destroying civilian property, deception by perfidy, wartime sexual violence, pillaging, and for any individual that is part of the command structure who orders any attempt to committing mass killings including genocide or ethnic cleansing, the granting of no quarter despite surrender, the conscription of children in the military and flouting the legal distinctions of proportionality and military necessity.
The Geneva Convention relative to the Protection of Civilian Persons in Time of War, more commonly referred to as the Fourth Geneva Convention and abbreviated as GCIV, is one of the four treaties of the Geneva Conventions. It was adopted in August 1949, and came into force in October 1950. While the first three conventions dealt with combatants, the Fourth Geneva Convention was the first to deal with humanitarian protections for civilians in a war zone. There are currently 196 countries party to the 1949 Geneva Conventions, including this and the other three treaties.
An unlawful combatant, illegal combatant or unprivileged combatant/belligerent is a person who directly engages in armed conflict in violation of the laws of war and therefore is claimed not to be protected by the Geneva Conventions. The International Committee of the Red Cross points out that the terms "unlawful combatant", "illegal combatant" or "unprivileged combatant/belligerent" are not defined in any international agreements. While the concept of an unlawful combatant is included in the Third Geneva Convention, the phrase itself does not appear in the document. Article 4 of the Third Geneva Convention does describe categories under which a person may be entitled to prisoner of war status. There are other international treaties that deny lawful combatant status for mercenaries and children.
The law of war is the component of international law that regulates the conditions for initiating war and the conduct of hostilities. Laws of war define sovereignty and nationhood, states and territories, occupation, and other critical terms of law.
Non-combatant is a term of art in the law of war and international humanitarian law to refer to civilians who are not taking a direct part in hostilities; persons, such as combat medics and military chaplains, who are members of the belligerent armed forces but are protected because of their specific duties ; combatants who are placed hors de combat; and neutral persons, such as peacekeepers, who are not involved in fighting for one of the belligerents involved in a war. This particular status was first recognized under the Geneva Conventions with the First Geneva Convention of 1864.
The Second Geneva Convention for the Amelioration of the Condition of Wounded, Sick and Shipwrecked Members of Armed Forces at Sea is one of the four treaties of the Geneva Conventions. The Geneva Convention for the Amelioration of the Condition of Wounded, Sick and Shipwrecked Members of Armed Forces at Sea was first adopted in 1949, replacing the Hague Convention (X) of 1907. It adapts the main protective regime of the First Geneva Convention to combat at sea.
The First Geneva Convention for the Amelioration of the Condition of the Wounded in Armies in the Field, held on 22 August 1864, is the first of four treaties of the Geneva Conventions. It defines "the basis on which rest the rules of international law for the protection of the victims of armed conflicts."
The Hague Conventions of 1899 and 1907 are a series of international treaties and declarations negotiated at two international peace conferences at The Hague in the Netherlands. Along with the Geneva Conventions, the Hague Conventions were among the first formal statements of the laws of war and war crimes in the body of secular international law. A third conference was planned for 1914 and later rescheduled for 1915, but it did not take place because of the start of World War I.
Francs-tireurs were irregular military formations deployed by France during the early stages of the Franco-Prussian War (1870–71). The term was revived and used by partisans to name two major French Resistance movements set up to fight against the Nazi Germany during World War II.
Legality of the Threat or Use of Nuclear Weapons[1996] ICJ 3 is a landmark international law case, where the International Court of Justice gave an advisory opinion stating that while the threat or use of nuclear weapons would generally be contrary to international humanitarian law, it cannot be concluded whether or not such a threat or use of nuclear weapons would be lawful in extreme circumstances where the very survival of a state would be at stake. The Court held that there is no source of international law that explicitly authorises or prohibits the threat or use of nuclear weapons but such threat or use must be in conformity with the UN Charter and principles of international humanitarian law. The Court also concluded that there was a general obligation to pursue nuclear disarmament.
International humanitarian law (IHL), also referred to as the laws of armed conflict, is the law that regulates the conduct of war. It is a branch of international law that seeks to limit the effects of armed conflict by protecting persons who are not participating in hostilities and by restricting and regulating the means and methods of warfare available to combatants.
Customary international law is an aspect of international law involving the principle of custom. Along with general principles of law and treaties, custom is considered by the International Court of Justice, jurists, the United Nations, and its member states to be among the primary sources of international law.
Protocol I is a 1977 amendment protocol to the Geneva Conventions concerning the protection of civilian victims of international war, such as "armed conflicts in which peoples are fighting against colonial domination, alien occupation or racist regimes". In practice, Additional Protocol I updated and reaffirmed the international laws of war stipulated in the Geneva Conventions of 1949 to accommodate developments of warfare since the Second World War (1937–1945).
The Geneva Convention on Prisoners of War was signed at Geneva, July 27, 1929. Its official name is the Convention relative to the Treatment of Prisoners of War, Geneva July 27, 1929. It entered into force 19 June 1931. It is this version of the Geneva Conventions which covered the treatment of prisoners of war during World War II. It is the predecessor of the Third Geneva Convention signed in 1949.
War can heavily damage the environment, and warring countries often place operational requirements ahead of environmental concerns for the duration of the war. Some international law is designed to limit this environmental harm.
Distinction is a principle under international humanitarian law governing the legal use of force in an armed conflict, whereby belligerents must distinguish between combatants and protected civilians. Combatant in this instance means persons entitled to directly participate in hostilities and thus are not afforded immunity from being directly targeted in situations of armed conflict. Protected civilian in this instance means civilians who are enemy nationals or neutral citizens outside of the territory of a belligerent power.
Air warfare must comply with laws and customs of war, including international humanitarian law by protecting the victims of the conflict and refraining from attacks on protected persons.
The Geneva Conventions are international humanitarian laws consisting of four treaties and three additional protocols that establish international legal standards for humanitarian treatment in war. The singular term Geneva Convention colloquially denotes the agreements of 1949, negotiated in the aftermath of the Second World War (1939–1945), which updated the terms of the two 1929 treaties and added two new conventions. The Geneva Conventions extensively define the basic rights of wartime prisoners, civilians and military personnel; establish protections for the wounded and sick; and provide protections for the civilians in and around a war-zone.
In international humanitarian law and international criminal law, an indiscriminate attack is a military attack that fails to distinguish between legitimate military targets and protected persons. Indiscriminate attacks strike both legitimate military and protected objects alike, thus violating the principle of distinction between combatants and protected civilians. They differ from direct attacks against protected civilians and encompass cases in which the perpetrators are indifferent as to the nature of the target, cases in which the perpetrators use tactics or weapons that are inherently indiscriminate, and cases in which the attack is disproportionate, because it is likely to cause excessive protected civilian casualties and damages to protected objects.
