List of war crimes


This article lists and summarizes the war crimes committed since the Hague Conventions of 1899 and 1907 and the crimes against humanity and crimes against peace that have been committed since these crimes were first defined in the Rome Statute.
Since many war crimes are not prosecuted, historians and lawyers will often make a serious case that war crimes occurred, even if there was no formal investigations or prosecution of the alleged crimes or an investigation cleared the alleged perpetrators.
War crimes under international law were firmly established by international trials such as the Nuremberg Trials and the Tokyo Trials, in which Austrian, German and Japanese leaders were prosecuted for war crimes committed during World War II.

1899–1902 Second Boer War

The term "concentration camp" was used to describe camps operated by the British Empire in South Africa during the Second Boer War in the years 1900–1902. As Boer farms were destroyed by the British under their "Scorched Earth" policy, many tens of thousands of women and children were forcibly moved into the concentration camps. Over 26,000 Boer women and children were to perish in these concentration camps.

1899–1902 Philippine–American War

In November 1901, the Manila correspondent of the Philadelphia Ledger wrote: "The present war is no bloodless, opera bouffe engagement; our men have been relentless, have killed to exterminate men, women, children, prisoners and captives, active insurgents and suspected people from lads of ten up, the idea prevailing that the Filipino as such was little better than a dog..."
In response to the Balangiga massacre, which wiped out a U.S. company garrisoning Samar town, U.S. Brigadier General Jacob H. Smith launched a retaliatory march across Samar with the instructions: "I want no prisoners. I wish you to kill and burn, the more you kill and burn the better it will please me. I want all persons killed who are capable of bearing arms in actual hostilities against the United States,..."
The war resulted in the deaths of at least 200,000 Filipino civilians. Some estimates for total civilian dead reach up to 1,000,000.

1914–1918: World War I

was the first major international conflict to take place following the codification of war crimes at the Hague Convention of 1907, including derived war crimes, such as the use of poisons as weapons, as well as crimes against humanity, and derivative crimes against humanity, such as torture, and genocide. Before, the Second Boer War took place after the Hague Convention of 1899. The Second Boer War is known for the first concentration camps for civilians in the 20th century.

1923–1932: Pacification of Libya

At least 50,000 people were executed during the Spanish Civil War. In his updated history of the Spanish Civil War, Antony Beevor writes, "Franco's ensuing 'white terror' claimed 200,000 lives. The 'red terror' had already killed 38,000." Julius Ruiz concludes that "although the figures remain disputed, a minimum of 37,843 executions were carried out in the Republican zone with a maximum of 150,000 executions in Nationalist Spain."
César Vidal puts the number of Republican victims at 110,965. In 2008 a Spanish judge, Socialist Baltasar Garzón, opened an investigation into the executions and disappearances of 114,266 people between 17 July 1936 and December 1951. Among the murders and executions investigated was that of poet and dramatist Federico García Lorca.

1939–1945: World War II

Axis powers

The Axis Powers were some of the most systematic perpetrators of war crimes in modern history. Contributing factors included Nazi race theory, a desire for "living space" that justified the eradication of native populations, and militaristic indoctrination that encouraged the terrorization of conquered peoples and prisoners of war. The Holocaust, the German attack on the Soviet Union and occupation of much of Europe, the Japanese occupation of Manchuria and the Philippines and attack on China all contributed to well over half of the civilian deaths in World War II and the conflicts that led up to the war. Even before post-war revelations of atrocities, Axis militaries were notorious for their brutal treatment of captured combatants.

Crimes perpetrated by Germany

According to the Nuremberg Trials, there were four major war crimes that were alleged against German military men and officers, each with individual events that made up the major charges.
1. Participation in a common plan of conspiracy for the accomplishment of crimes against peace
2. Planning, initiating and waging wars of aggression and other crimes against peace
3. War Crimes
Atrocities against enemy combatants or conventional crimes committed by military units, and include:
4. Crimes against Humanity
Crimes committed well away from the lines of battle and unconnected in any way to military activity, distinct from war crimes
Other crimes against humanity included:
At least 10 million, and perhaps over 20 million perished directly and indirectly due to the commission of crimes against humanity and war crimes by the Nazi regime, of which the Holocaust lives on in particular infamy, for its particularly cruel nature and scope, and the industrialised nature of the genocide of Jewish citizens of states invaded or controlled by the Nazi regime. At least 5.9 million Jews were murdered by the Nazis, or 66 to 78% of Europe's Jewish population, although a complete count may never be known. Though much of Continental Europe suffered under the Nazi occupation, Poland, in particular, was the state most devastated by these crimes, with 90% of its Jews as well as many ethnic Poles slaughtered by the Nazis and their affiliates. After the war, from 1945–49, the Nazi regime was put on trial in two tribunals in Nuremberg, Germany by the victorious Allied powers.
The first tribunal indicted 24 major Nazi war criminals, and resulted in 19 convictions and 3 acquittals, 2 of the accused died before a verdict was rendered, at least one of which by killing himself with cyanide. The second tribunal indicted 185 members of the military, economic, and political leadership of Nazi Germany, of which 142 were convicted and 35 were acquitted. In subsequent decades, approximately 20 additional war criminals who escaped capture in the immediate aftermath of World War II were tried in West Germany and Israel. In Germany and many other European nations, the Nazi Party and denial of the Holocaust is outlawed.

Two wounded Australians managed to escape the massacre and provide eyewitness accounts of the Japanese treatment of wounded prisoners of war, as did locals who witnessed the massacre. Official records indicate that 150 wounded men were killed.
Laha massacre, 1942War crimes In 1946, the Laha massacre and other incidents which followed the fall of Ambon became the subject of the largest ever war crimes trial, when 93 Japanese personnel were tried by an Australian tribunal, at Ambon.

Palawan Massacre, 1944War crimes In 1948, in Lt. Gen. Seiichi Terada was accused of failing to take command of the soldiers in the Puerto Princesa camp. Master Sgt. Toru Ogawa and Superior Private Tomisaburo Sawa were the only few soldiers who were charged for the actual involvement since most of the soldiers garrisoned in the camp had either died or went missing in the days following the victory of the Philippines campaign. In 1958, all charges were dropped and sentences were reduced.Following the US invasion of Luzon in 1944, the Japanese high command ordered that all POWs remaining in the island are to be exterminated at all cost. As a result, on December 14, 1944, units from the Japanese Fourteenth Area Army stationed in the Puerto Princesa POW camp in Palawan rounded up 150 remaining POWs still garrisoned in the camp, herded them into air raid shelters, before dousing the shelters with gasoline and setting it on fire.

Yamashita pleaded inability to act and lack of knowledge of the massacre, due to his commanding other operations in the area. The defense failed, establishing the Yamashita Standard, which holds that a commander who makes no meaningful effort to uncover and stop atrocities is as culpable as if he had ordered them. His chief of staff Akira Mutō was condemned by the Tokyo tribunal.

Crimes perpetrated by Romania

Crimes perpetrated by the Chetniks

ideology revolved around the notion of a Greater Serbia within the borders of Yugoslavia, to be created out of all territories in which Serbs were found, even if the numbers were small. A directive dated 20 December 1941, addressed to newly appointed commanders in Montenegro, Major Đorđije Lašić and Captain Pavle Đurišić, outlined, among other things, the cleansing of all non-Serb elements in order to create a Greater Serbia:
kill a Partisan through heart extraction
The Chetniks systemically massacred Muslims in villages that they captured. In late autumn of 1941 the Italians handed over the towns of Višegrad, Goražde, Foča and the surrounding areas, in south-east Bosnia to the Chetniks to run as a puppet administration and NDH forces were compelled by the Italians to withdraw from there. After the Chetniks gained control of Goražde on 29 November 1941, they began a massacre of Home Guard prisoners and NDH officials that became a systematic massacre of the local Muslim civilian population.
Several hundred Muslims were murdered and their bodies were left hanging in the town or thrown into the Drina river. On 5 December 1941, the Chetniks received the town of Foča from the Italians and proceeded to massacre around 500 Muslims. Additional massacres against the Muslims in the area of Foča took place in August 1942. In total, more than 2000 people were killed in Foča.
In early January, Chetniks entered Srebrenica and killed around 1000 Muslim civilians there and in nearby villages. Around the same time the Chetniks made their way to Višegrad where deaths were reportedly in the thousands. Massacres continued in the following months in the region. In the village of Žepa alone about three hundred were killed in late 1941. In early January, Chetniks massacred fifty-four Muslims in Čelebić and burned down the village. On 3 March, Chetniks burned forty-two Muslim villagers to death in Drakan.
In early January 1943 and again in early February, Montenegrin Chetnik units were ordered to carry out "cleansing actions" against Muslims, first in the Bijelo Polje county in Sandžak and then in February in the Čajniče county and part of Foča county in southeastern Bosnia, and in part of the Pljevlja county in Sandžak.
Pavle Đurišić, the officer in charge of these operations, reported to Mihailović, Chief of Staff of the Supreme Command, that on 10 January 1943: "thirty-three Muslim villages had been burned down, and 400 Muslim fighters and about 1,000 women and children had been killed, as against 14 Chetnik dead and 26 wounded".
In another report sent by Đurišić dated 13 February 1943, he reported that: "Chetniks killed about 1,200 Muslim fighters and about 8,000 old people, women, and children; Chetnik losses in the action were 22 killed and 32 wounded". He added that "during the operation the total destruction of the Muslim inhabitants was carried out regardless of sex and age". The total number of deaths caused by the anti-Muslim operations between January and February 1943 is estimated at 10,000. The casualty rate would have been higher had a great number of Muslims not already fled the area, most to Sarajevo, when the February action began. According to a statement from the Chetnik Supreme Command from 24 February 1943, these were countermeasures taken against Muslim aggressive activities; however, all circumstances show that these massacres were committed in accordance with implementing the directive of 20 December 1941.
Actions against the Croats were of a smaller scale but comparable in action. In early October 1942 in the village of Gata, where an estimated 100 people were killed and many homes burnt in reprisal taken for the destruction of roads in the area carried out on the Italians' account. That same month, formations under the command of Petar Baćović and Dobroslav Jevđević, who were participating in the Italian Operation Alfa in the area of Prozor, massacred over 500 Croats and Muslims and burnt numerous villages. Baćović noted that "Our Chetniks killed all men 15 years of age or older. ... Seventeen villages were burned to the ground." Mario Roatta, commander of the Italian Second Army, objected to these "massive slaughters" of noncombatant civilians and threatened to halt Italian aid to the Chetniks if they did not end.

Crimes perpetrated by the Ustashas

The Ustaša intended to create an ethnically "pure" Greater Croatia, and they viewed those Serbs then living in Croatia, Bosnia and Herzegovina as the biggest obstacle to this goal. Ustasha ministers Mile Budak, Mirko Puk and Milovan Žanić declared in May 1941 that the goal of the new Ustasha policy was an ethnically pure Croatia. The strategy to achieve their goal was:
  1. One-third of the Serbs were to be killed
  2. One-third of the Serbs were to be expelled
  3. One-third of the Serbs were to be forcibly converted to Catholicism
The Independent State of Croatia government cooperated with Nazi Germany in the Holocaust and exercised their own version of the genocide against Serbs, as well as Jews and Gypsies inside its borders. State policy towards Serbs had first been declared in the words of Milovan Žanić, a minister of the NDH Legislative council, on 2 May 1941:
This country can only be a Croatian country, and there is no method we would hesitate to use in order to make it truly Croatian and cleanse it of Serbs, who have for centuries endangered us and who will endanger us again if they are given the opportunity.
According to the Simon Wiesenthal Center, "Ustasa terrorists killed 500,000 Serbs, expelled 250,000 and forced 250,000 to convert to Roman Catholicism. They murdered thousands of Jews and Gypsies." The execution methods used by the Ustasha were particularly brutal and sadistic and often included torture, dismemberment or decapitation. A Gestapo report to Heinrich Himmler from 1942 stated, "The Ustaše committed their deeds in a bestial manner not only against males of conscript age but especially against helpless old people, women and children."
Numerous concentration camps were built in the NDH, most notably Jasenovac, the largest, where around 100,000 Serbs, Jews, Roma, as well as a number of Croatian political dissidents, died, mostly from torture and starvation. It was established in August 1941 and not dismantled until April 1945, shortly before the end of the war. Jasenovac was a complex of five subcamps and three smaller camps spread out over, in relatively close proximity to each other, on the bank of the Sava river. Most of the camp was at Jasenovac, about southeast of Zagreb. The complex also included large grounds at Donja Gradina directly across the Sava River, the Jastrebarsko children's camp to the northwest, and the Stara Gradiška camp for women and children to the southeast.
Unlike Nazi camps, most murders at Jasenovac were done manually using hammers, axes, knives and other implements. According to testimony, on the night of August 29, 1942, guards at the camp organized a competition to see who could slaughter the most inmates, with guard and former Franciscan priest Petar Brzica winning by cutting the throats of 1,360 inmates. A special knife called called a "Srbosjek" was designed for the slaughtering of prisoners. Prisoners were sometimes tied with barbed wire, then taken to a ramp near to the Sava River where weights were placed on the wires, their throats and stomachs slashed before their bodies were dumped into the river. After unsuccessful experiments with gas vans, camp commander Vjekoslav Luburić had a gas chamber built at Jasenovac V, where a considerable number of inmates were killed during a three-month experiment with sulfur dioxide and Zyklon B, but this method was abandoned due to poor construction. The Ustashe cremated living inmates as well as corpses. Other methods of torture and killing done included: inserting hot nails under finger nails, mutilating parts of the body including plucking out eyeballs, tightening chains around ones head until the skull fractured and the eyes popped and also, placing salt in open wounds. Women were subjected to rape and torture, including breast mutilation. Pregnant women had their wombs cut out.
An escape attempt on 22 April 1945 by 600 male inmates failed and only 84 male prisoners escaped successfully. The remainder and about 400 other prisoners were then murdered by Ustasha guards, despite the fact that they knew the war was ending with Germany's capitulation. All the female inmates from the women's camp had been massacred by the guards the previous day. The guards then destroyed the camp and everything associated with it was burned to the ground. Other concentration camps were the Đakovo camp, Gospić camp, Jadovno camp, Kruščica camp and the Lepoglava camp.
Ustasha militias and death squads also burnt villages and killed thousands of civilian Serbs in the country-side in sadistic ways with various weapons and tools. Men, women, children were hacked to death, thrown alive into pits and down ravines, or set on fire in churches. Some Serb villages near Srebrenica and Ozren were wholly massacred, while children were found impaled by stakes in villages between Vlasenica and Kladanj. The Glina massacres, where thousands of Serbs were killed, are among the more notable instances of Ustasha cruelty.
Ante Pavelić, leader of the Ustasha, fled to Argentina and Spain which gave him protection, and was never extradited to stand trial for his war crimes. Pavelić died on 28 December 1959 at the Hospital Alemán in Madrid, where the Roman Catholic church had helped him to gain asylum, at the age of 70 from gunshot wounds sustained in an earlier assassination attempt by Montenegrin Blagoje Jovović. Some other prominent Ustashe figures and their respective fates:
Most Ustashe fled the country following the war, mainly with the help of Father Krunoslav Draganović, secretary of the College of Sian Girolamo who helped Ustasha fugitives immigrate illegally to South America.

Crimes perpetrated by the Ukrainian nationalists

The Ukrainian OUN-B group, along with their military force – Ukrainian Insurgent Army – are responsible for a genocide on the Polish population in Volhynia and Eastern Galicia. Starting in March 1943, with its peak in the summer 1943, as many as 80,000 -100,000. Although the main target were Poles, many Jews, Czechs and those Ukrainians unwilling to participate in the crimes, were massacred as well. Lacking good armament and ammunition, UPA members commonly used tools such as axes and pitchforks for the slaughter. As a result of these massacres, almost the entire non-Ukrainian population of Volhynia was either killed or forced to flee. However, the premix of this ethnic cleansing was the war of Polish partisan Homeland Army against Ukraine, in which Poland wanted to re-occupy Western Ukraine, treacherously captured in 1921. Homeland Army committed a genocide of Ukrainians during this conquest campaign, killed as many as 15000 mostly in near-border villages and practiced unprecedented cruelty against UPA partisans.

American mutilation of Japanese war deadWar crimes Though there are no known prosecutions, the occasional mutilation of Japanese remains were recognised to have been conducted by U.S. forces, declared to be atrocities, and explicitly forbidden by order of the U.S. Judge Advocate General in 1943–1944.Many dead Japanese were desecrated and/or mutilated, for example by taking body parts as souvenirs or trophies. This is in violation of the law and custom of war, as well as the 1929 Geneva Convention on the Sick and Wounded which was paraphrased as saying "After every engagement, the belligerent who remains in possession of the field shall take measures to search for wounded and the dead and to protect them from robbery and ill-treatment." in a 1944 memorandum for the U.S. Assistant Chief of the Staff.

IncidentType of crimePersons responsibleNotes
Razing of FriesoytheBreach of The 1907 Convention Respecting the Laws and Customs of War on Land, Article 23, which prohibits acts that "destroy or seize the enemy's property, unless such destruction or seizure be imperatively demanded by the necessities of war."No investigation; no prosecutions. Major-general Christopher Vokes commander of the Canadian 4th Armoured Division freely admitted ordering the action, commenting in his autobiography that he had "No feeling of remorse over the elimination of Friesoythe."In April 1945 the town of Friesoythe in north-west Germany was deliberately destroyed by the Canadian 4th Armoured Division acting on the orders of its commander, Major-general Christopher Vokes. The destruction was ordered in retaliation for the killing of a Canadian battalion commander. Vokes may have believed at the time that this killing had been carried out by German civilians. The rubble of the town was used to fill craters in the local roads.

Almost 20 years of fighting... has killed half a million people. Many of the dead are children... The LRA kidnaps children and forces them to join its ranks. And so, incredibly, children are not only the main victims of this war, but also its unwilling perpetrators... The girls told me they had been given to rebel commanders as "wives" and forced to bear them children. The boys said they had been forced to walk for days knowing they would be killed if they showed any weakness, and in some cases forced even to murder their family members... every night up to 10,000 children walk into the centre of Kitgum... because they are not safe in their own beds... more than 25,000 children have been kidnapped...this year an average of 20 children have been abducted every week.

During the Algerian Civil War of the 1990s, a variety of massacres occurred through the country, many being identified as war crimes. The Armed Islamic Group has avowed its responsibility for many of them, while for others no group has claimed responsibility. In addition to generating a widespread sense of fear, these massacres and the ensuing flight of population have resulted in serious depopulation of the worst-affected areas. The massacres peaked in 1997, and were particularly concentrated in the areas between Algiers and Oran, with very few occurring in the east or in the Sahara.

1994–1996/1999–2009: Russia-Chechnya Wars

2003–2011: Iraq War

; During the Iraq War
Allegations of war crimes in the 2006 Lebanon War refer to claims of various groups and individuals, including Amnesty International, Human Rights Watch, and United Nations officials, who accused both Hezbollah and Israel of violating international humanitarian law during the 2006 Lebanon War, and warned of possible war crimes. These allegations included intentional attacks on civilian populations or infrastructure, disproportionate or indiscriminate attacks in densely populated residential districts.
According to various media reports, between 1,000 and 1,200 Lebanese citizens were reported dead; there were between 1,500 and 2,500 people wounded and over 1,000,000 were temporarily displaced. Over 150 Israelis were killed ; thousands wounded; and 300,000–500,000 were displaced because of Hezbollah firing tens of thousands of rockets at major cities in Israel.

2003–2009/2010: Darfur conflict; 2005–2010: Civil war in Chad

During the Darfur conflict, Civil war in Chad
The conflict in Darfur has been variously characterised as a genocide.
Sudanese authorities claim a death toll of roughly 19,500 civilians while many non-governmental organizations, such as the Coalition for International Justice, claim over 400,000 people have been killed.
In September 2004, the World Health Organization estimated there had been 50,000 deaths in Darfur since the beginning of the conflict, an 18-month period, mostly due to starvation. An updated estimate the following month put the number of deaths for the 6-month period from March to October 2004 due to starvation and disease at 70,000; These figures were criticised, because they only considered short periods and did not include deaths from violence. A more recent British Parliamentary Report has estimated that over 300,000 people have died, and others have estimated even more.

2008–2009 Gaza War

There were allegations of war crimes by both the Israeli military and Hamas. Criticism of Israel's conduct focused on the proportionality of its measures against Hamas, and on its alleged use of weaponised white phosphorus. Numerous reports from human right groups during the war claimed that white phosphorus shells were being used by Israel, often in or near populated areas. In its early statements the Israeli military denied using any form of white phosphorus, saying "We categorically deny the use of white phosphorus". It eventually admitted to its limited use and stopped using the shells, including as a smoke screen. The Goldstone report investigating possible war crimes in the 2009 war accepted that white phosphorus is not illegal under international law but did find that the Israelis were "systematically reckless in determining its use in build-up areas". It also called for serious consideration to be given to the banning of its use as an obscurant.

2009 Sri Lankan Civil War

There are allegations that war crimes were committed by the Sri Lankan military and the rebel Liberation Tigers of Tamil Eelam during the Sri Lankan Civil War, particularly during the final months of the conflict in 2009. The alleged war crimes include attacks on civilians and civilian buildings by both sides; executions of combatants and prisoners by the government of Sri Lanka; enforced disappearances by the Sri Lankan military and paramilitary groups backed by them; acute shortages of food, medicine, and clean water for civilians trapped in the war zone; and child recruitment by the Tamil Tigers.
A panel of experts appointed by UN Secretary-General Ban Ki-moon to advise him on the issue of accountability with regard to any alleged violations of international human rights and humanitarian law during the final stages of the civil war found "credible allegations" which, if proven, indicated that war crimes and crimes against humanity were committed by the Sri Lankan military and the Tamil Tigers. The panel has called on the UNSG to conduct an independent international inquiry into the alleged violations of international law. The Sri Lankan government has denied that its forces committed any war crimes and has strongly opposed any international investigation. It has condemned the UN report as "fundamentally flawed in many respects" and "based on patently biased material which is presented without any verification".

2011–present: Syrian civil war

International organizations have accused the Syrian government, ISIL and other opposition forces of severe human rights violations, with many massacres occurring. Chemical weapons have been used many times during the conflict as well. The Syrian government is reportedly responsible for the majority of civilian casualties and war crimes, often through bombings. In addition, tens of thousands of protesters and activists have been imprisoned and there are reports of torture in state prisons. Over 470,000 people were killed in the war by 2017.
