Einsatzgruppen (German for "task forces", ""deployment groups""; singular "Einsatzgruppe"; official full name Einsatzgruppen der Sicherheitspolizei und des SD) were "Schutzstaffel" (SS) paramilitary death squads of Nazi Germany that were responsible for mass killings, primarily by shooting, during World War II.
 The "Einsatzgruppen" had a leading role in the implementation of the Final Solution of the Jewish question ("Die Endlösung der Judenfrage") in territories conquered by Nazi Germany.
The LaSalle Heights disaster occurred in the early morning of March 1, 1965 in the city of LaSalle, Quebec when a gas line explosion destroyed a number of low-cost housing units.
 In all, 28 people lost their lives, 39 were injured and 200 left homeless.
 Most of the casualties were women and children because many men had left for work.
 The casualties might have been higher had it not been the start of the month when many men left earlier than usual to pay their monthly rent at the rental office.
The Sombra Negra (Spanish for "Black Shadow"), also known as "El Clan de Planta" ("The Plant Clan"), are (as of 2014) death squad groups based in El Salvador, allegedly composed mostly of police and military personnel, that target criminals and gang members for vigilante justice.
 The name first appeared around December 1989 in the Department of San Miguel.
 By April 1995, the group stated that it had killed 17 people, claiming that the dead were criminals or members of gangs.
 Recent years have also seen increasing accusations of continuing death squad activity targeting the Salvadoran political opposition and members of the political and social left.
 These vigilante groups are originally based in El Salvador and are not under the official jurisdiction of the government of El Salvador, which can be easily confused.
 Many Sombra Negra and/or death squads that are caught are incarcerated in separate prisons for their own safety.
An Aso Oke Hat (pronounced ), a type of soft fez, is a traditional Yoruba hat that is made of hand woven Aso Oke, cotton, velvet, or damask.
 In the Yoruba language, this hat is called a fila.
 Although these hats originated in Nigeria they are worn by many men of African descent.
 Typically, the top of the hat slouches to one side, and rests above the wearer's ear.
 It is commonly worn with the Yoruba formal attire, Agbada (equally made with Aso Oke, lace or cotton) or brocade dashiki suits.
 Many men wear a bowler hat with the lace dashiki suit.
 However, an aso oke hat or crown style kufi cap are the most common choices when wearing any other type of formal attire.
The July 2009 Ürümqi riots were a series of violent riots over several days that broke out on 5 July 2009 in Ürümqi, the capital city of the Xinjiang Uyghur Autonomous Region (XUAR), in northwestern People's Republic of China (PRC).
 The first day's rioting, which involved at least 1,000 Uyghurs, began as a protest but escalated into violent attacks that mainly targeted Han people.
 People's Armed Police were deployed, and two days later hundreds of Han people clashed with both police and Uyghurs.
 PRC officials said that a total of 197 people died, among those killed most of them are Hans, with 1,721 others injured and many vehicles and buildings destroyed; however, Uyghur exile groups say the death toll is higher.
 Many men disappeared during wide-scale police sweeps in the days following the riots; Human Rights Watch (HRW) documented 43 cases and said figures for real disappearances were likely to be much higher.
Franz Walter Stahlecker (10 October 1900 – 23 March 1942) was commander of the SS security forces ("Sicherheitspolizei" (SiPo) and the "Sicherheitsdienst" (SD)) for the "Reichskommissariat Ostland" in 1941–42.
 Stahlecker commanded "Einsatzgruppe A", the most murderous of the four "Einsatzgruppen" (death squads during the Holocaust) active in German-occupied Eastern Europe.
 He was killed in action by Soviet partisans and was replaced by Heinz Jost.
In the beginning of August 1941, the Jews of the village, about 70-80 men and over 100 women and children were assassinated.
 The mass execution was perpetrated by an Einsatzgruppen of German and Lithuanian nationalists.
Einsatzgruppen (] , "task forces" "deployment groups") were "Schutzstaffel" (SS) paramilitary death squads of Nazi Germany that were responsible for mass killings, primarily by shooting, during World War II (1939–45).
 The "Einsatzgruppen" were involved in the murder of much of the intelligentsia and cultural elite of Poland, and had an integral role in the implementation of the so-called Final solution to the Jewish question ("Die Endlösung der Judenfrage") in territories conquered by Nazi Germany.
 Almost all of the people they killed were civilians, beginning with the intelligentsia and swiftly progressing to Soviet political commissars, Jews, and Gypsies as well as actual or alleged partisans throughout Eastern Europe.
A death squad is an armed group that conducts extrajudicial killings or forced disappearances of persons for the purposes of political repression, genocide, or revolutionary terror.
 These killings are often conducted in ways meant to ensure the secrecy of the killers' identities.
 Death squads may have the support of domestic or foreign governments (see state terrorism).
 They may comprise a secret police force, paramilitary groups, government soldiers, policemen, or combinations thereof.
 They may also be organized as vigilantes.
 When death squads are not controlled by the state, they may consist of insurgent forces or organized crime.
The "Dirty War" (Spanish: "Guerra Sucia" ), was the name used by the Argentine Military Government for a period of state terrorism in Argentina from roughly 1974 to 1983 (some sources date the beginning to 1969), during which military and security forces and right-wing death squads in the form of the Argentine Anticommunist Alliance (Triple A) hunted down and killed left-wing guerrillas, political dissidents, and anyone believed to be associated with socialism.
 About 30,000 people disappeared, many of which were impossible to be formally reported due to the nature of the issue: state terrorism.
 The targets were left-wing activists, guerrillas and militants, trade unionists, students, journalists and Marxists and Peronist guerrillas and their support network in the Montoneros believed to be 150,000-250,000-strong and 60,000-strong in the ERP, as well as alleged sympathizers.
 Some 10,000 of the "disappeared" were guerrillas of the Montoneros (MPM) and the Marxist People's Revolutionary Army (ERP) although the lowest estimate is that the Montoneros and ERP had a combined strength of 5,000.
 The "disappeared" included those thought to be a political or ideological threat to the military junta, even vaguely, and they were killed in an attempt by the junta to silence the opposition and break the determination of the guerrillas.
 The worst repression reportedly occurred after the guerillas were largely defeated in 1977, when the church, labor unions, artists, intellectuals and university students and professors were targeted.
 Although the Montoneros reported having carried out some 600 armed attacks in 1977, the guerrilla threat had greatly declined.
 The junta justified this mass terror by exaggerating the guerrilla threat, and even staged attacks to be blamed on guerillas and used frozen dead bodies of guerilla fighters that had been kept in storage for this purpose.
 In late 1979, Amnesty International accused the Videla military government of being responsible for the disappearance of 15,000 to 20,000 Argentine citizens since the 1976 coup.
 That year, a special study by the New York City Bar concluded that around 10,000 Argentines had disappeared since the coup.
 According to "Registro Unificado de Víctimas del Terrorismo de Estado" (Ruvte), 662 were disappeared under the presidency of Isabel Perón and 6,348 were disappeared during the military dictatorship.
