Mass killings in the context of Anton Weiss-Wendt

The East Timor genocide refers to the campaign of systematic killings, repression and state terrorism against the East Timorese people by Indonesia's New Order regime between 1975 and 1999, during the invasion and subsequent occupation of East Timor.

The Indonesian military framed their counter-insurgency operations as "pacification" and "anti-communist stabilisation" while operating with total impunity and engaging in a large-scale extermination of the East Timor's population, including mass killings, forced displacement, starvation, and the destruction of East Timor's social and political fabric. During the occupation period, the Indonesian government received diplomatic and military support from Australia and the United States.

Investigative Assistance for Violent Crimes Act of 2012 (IAVCA) is a federal law in the United States that clarifies the statutory authority for federal law enforcement agencies to provide investigatory assistance to the States. The Act provided that, upon request from a state or local government, federal law enforcement may assist in the investigation of violent crime occurring in non-federal, public places. The Act did not create any new crimes but rather mandated a definition, across federal law enforcement agencies, of "mass killings" as a killing of three or more victims in the same incident. The Act enabled the Federal Bureau of Investigation to develop a program of research and training to address active shooter incidents.

The White Terror (Russian: Белый террор, romanized: Belyy terror) in the former Russian Empire refers to violence and mass killings carried out by the White movement and its governments of Russia during the Russian Civil War (1917–1923). Individual acts against Bolshevik rule, such as assassinations, commenced at least by the end of 1917. Violence on any sizable scale on the part of the Whites arguably began in early 1918, continuing until the defeat of the Whites at the hands of the Red Army from 1920 to 1922. Unlike in the case of the Red Terror, there was no formal decree which kickstarted the White Terror. The White Terror was most acute in the Far East, under warlords such as Grigory Semyonov and Baron Roman von Ungern-Sternberg.

Though the Bolsheviks' Red Terror officially began on September 5, 1918 in response to several planned assassinations of Bolshevik leaders, incidents of violence carried out by Bolsheviks and their supporters had been ongoing since the October Revolution. According to some Russian historians, the White Terror was a series of premeditated actions directed by their leaders; this view is contested by Russian historians who view it as spontaneous and disorganized. According to some historians, the White Terror evolved from a disorganized policy to a system of political repression sanctioned by the Russian State and its system of military dictatorship which targeted not only the Bolsheviks, but members of other parties and other people as well. Some historians believe the antisemitic pogroms carried out by the Whites to be a part of the White Terror.

The Masalit genocide is a series of ongoing persecutions and mass killings of the Masalit people in West Darfur carried out by the Rapid Support Forces (RSF) and its allies as part of the Darfur genocide. The genocide has been recognized by Genocide Watch, the government of the United States, American academic Eric Reeves, Governor of West Darfur Khamis Abakar, and The Economist.

The genocide started in 2023 when the RSF began committing organized massacres of Masalit civilians in Darfur days after the beginning of the Sudanese civil war. It has encompassed the Ardamata massacre, Misterei massacre, and Battle of Geneina, all of which targeted Masalit civilians in the area of Geneina in West Darfur, as well as the El Fasher massacre, which is targeting the Zaghawa people in North Darfur.

The July massacre was the violent suppression and mass killings in Bangladesh during the July Revolution from 16 July to 5 August 2024. Triggered by the reinstatement of a controversial quota system and widespread public dissatisfaction, the crackdown was carried out by the government led by the Awami League, its affiliated groups such as the Chhatra League, and various law-enforcement agencies.

In June 2024, the Bangladesh Supreme Court reinstated the quota system in government jobs, triggering the resurgence of the quota reform movement in early July. Following weeks of demonstrations, tensions escalated on July 15 after clashes between protesters and members of the Chhatra League. In the days that followed, law enforcement agencies, including the Police, RAB, and BGB, as well as members of the ruling party's student, youth and volunteer wings, were involved in violent confrontations with the protesters. These clashes resulted in numerous deaths, including among protesters, law enforcement personnel, party members, bystanders, and children. By early August, the violence had resulted in substantial casualties, with estimates of fatalities ranging from two hundred to one thousand, and thousands more reported injured.
