List of war crimes
27):

Almost 20 years of fighting... has killed half a million people. Many of the dead are children... The LRA [a cannibalism cult] 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.
The International Criminal Court has launched an investigation and has issued indictments against LRA leaders.

1990–2000: Liberia / Sierra Leone: From The Times March 28, 2006 p. 43:

"Charles Taylor, the former Liberian President who is one of Africas most wanted men, has gone into hiding in Nigeria to avoid extradition to a UN war crimes tribunal... The UN war crimes tribunal in Sierra Leone holds Mr Taylor responsible for about 250,000 deaths. Throughout the 1990s, his armies and supporters, made up of child soldiers orphaned by the conflict wreaked havoc through a swath of West Africa. In Sierra Leone he supported the Revolutionary United Front (R.U.F) whose rebel fighters were notorious for hacking off the limbs of civilians.
Current action – Indicted on 17 counts of war crimes and crimes against humanity by the UN, which has issued an international warrant for his arrest. As of April 2006 located, extradited, and facing trial in Sierra Leone but then transferred to the Netherlands as requested by the Liberian government. As of the status of the main state actor in the war crimes in Liberia, Sierra Leone and the ongoing war crimes tribunal in the Hague for violating the UN sanctions, Libya's Muamar Gaddafi was elected to the post of President of the African Union. As of late January, 2011, Exxon/Mobile has resumed explorationary drilling in Libya after the exchange of the Lockerbie bombing terrorist was returned to Libya and Libya was taken off terrorist list by the Bush administration with the legal stipulation that Libya could never be prosecuted for past war crimes(regardless of guilt)in the future.

1990: Gulf War: 

1991–2000/2002: Algerian Civil War: 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 (GIA) 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 (with a smaller peak in 1994), 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: During the First Chechen War (1994–1996) and Second Chechen War (1999–2000 battle phase, 2000–2009 insurgency phase) there were many allegations of war crimes and terrorism against both sides from various human rights organizations.

1998–2006: Second Congo War: Civil war 1998–2002, est. 5 million deaths; war "sucked in" Rwanda, Uganda, Angola, Zimbabwe and Namibia, as well as 17,000 United Nations peacekeepers, its "largest and most costly" peace mission and "the bloodiest conflict since the end of the Second World War."
Fighting involves Mai-Mai militia and Congolese government soldiers. The Government originally armed the Mai-Mai as civil defence against external invaders, who then turned to banditry.
100,000 refugees living in remote disease ridden areas to avoid both sides
Estimated 1000 deaths a day according to Oxfam:
"The army attacks the local population as it passes through, often raping and pillaging like the militias. Those who resist are branded Mai-mai supporters and face detention or death. The Mai-mai accuse the villagers of collaborating with the army, they return to the villages at night and extract revenge [sic]. Sometimes they march the villagers into the bush to work as human mules."
In 2003, Sinafasi Makelo, a representative of Mbuti Pygmies, told the UN's Indigenous People's Forum that during the Congo Civil War, his people were hunted down and eaten as though they were game animals. Both sides of the war regarded them as "subhuman". Makelo asked the UN Security Council to recognise cannibalism as a crime against humanity and an act of genocide.

2003–2017: Iraqi conflict: During the Iraq War

Blackwater Baghdad shootings On September 16, 2007, Blackwater military contractors shot and killed 17 Iraqi civilians in Nisour Square, Baghdad. The fatalities occurred while a Blackwater Personal Security Detail (PSD) was escorting a convoy of US State Department vehicles en route to a meeting in western Baghdad with United States Agency for International Development officials. The shooting led to the unraveling of the North Carolina-based company, which since has replaced its management and changed its name to Xe Services.
Beginning in 2004, accounts of physical, psychological, and sexual abuse, including torture, rape, sodomy, and homicide of prisoners held in the Abu Ghraib prison in Iraq (also known as Baghdad Correctional Facility) came to public attention. These acts were committed by military police personnel of the United States Army together with the CIA. In January 2014, evidence accuses British troops of being involved in widespread torture and abuse towards Iraqi civilians and prisoners.
War crimes: 2006 al-Askari Mosque bombing by Al-Qaeda. The bombing was followed by retaliatory violence with over a hundred dead bodies being found the next day and well over 1,000 people killed in the days following the bombing – by some counts, over 1,000 on the first day alone.
The Mahmudiyah rape and killings were the gang-rape and murder of 14-year-old Iraqi girl Abeer Qassim Hamza al-Janabi and the murder of her family by United States Army soldiers on March 12, 2006. It occurred in the family's house to the southwest of Yusufiyah, a village to the west of the town of Al-Mahmudiyah, Iraq. Other members of al-Janabi's family murdered by Americans included her 34-year-old mother Fakhriyah Taha Muhasen, 45-year-old father Qassim Hamza Raheem, and 6-year-old sister Hadeel Qassim Hamza Al-Janabi. The two remaining survivors of the family, 9-year-old brother Ahmed and 11-year-old brother Mohammed, who were at school during the massacre, were orphaned by the event.
War crimes: Iraqi insurgent groups have committed many armed attacks and bombings targeting civilians. According to Iraqi Interior Minister Bayan Jabr insurgents killed over 12,000 Iraqis from January 2005 to June 2006, giving the first official count for the victims of bombings, ambushes and other deadly attacks. Iraq Body Count project data shows that 33% of civilian deaths during the Iraq War resulted from execution after abduction or capture. These were overwhelmingly carried out by unknown actors including insurgents, sectarian militias and criminals. See: Iraq War insurgent attacks, List of suicide bombings in Iraq since 2003 and List of massacres of the Iraq War for a more comprehensive list.

2006 Lebanon 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 (including Hezbollah fighters) 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 (120 military); thousands wounded; and 300,000–500,000 were displaced because of Hezbollah firing tens of thousands of rockets at major cities in Israel.

2003–2020 War in Darfur and Chadian Civil War: During the War in Darfur and the Chadian Civil War, reports of humans rights abuses and genocide surfaced, accusing the Sudanese Armed Forces and Janjaweed militias in Darfur and Eastern Chad.
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.
