Enforced disappearance in the context of "Dirty War"

The Russian-occupied territories of Ukraine are areas of southern and eastern Ukraine that are controlled by Russia as a result of the Russo-Ukrainian War and the ongoing invasion. In Ukrainian law, they are defined as the "temporarily occupied territories". As of 2024, Russia occupies almost 20% of Ukraine and about 3 to 3.5 million Ukrainians are estimated to be living under occupation; since the invasion, the occupied territories lost roughly half of their population. The United Nations Human Rights Office reports that Russia is committing severe human rights violations in occupied Ukraine, including arbitrary detentions, enforced disappearances, torture, crackdown on peaceful protest and freedom of speech, enforced Russification, passportization, indoctrination of children, and suppression of Ukrainian language and culture.

The occupation began in 2014 with Russia's invasion and annexation of Crimea, and its de facto takeover of Ukraine's Donbas during a war in eastern Ukraine. In 2022, Russia launched a full-scale invasion. However, due to fierce Ukrainian resistance and logistical challenges (e.g. the stalled Russian Kyiv convoy), the Russian Armed Forces retreated from northern Ukraine in early April. In September 2022, Ukrainian forces launched the Kharkiv counteroffensive and liberated most of that oblast. Another southern counteroffensive resulted in the liberation of Kherson that November.

Disappeared Detainees (Spanish: detenidos desaparecidos, DD. DD) is the term commonly used in Latin American countries to refer to the victims of kidnappings, usually taken to clandestine detention and torture centers, and crimes of forced disappearance, committed by various authoritarian military dictatorships during the 1970s and 1980s, and officially recognized, among others, by the governments of Argentina (1984) and Chile (1991).

At 7:15 p.m. on September 23, 1972, President Ferdinand Marcos announced on television that he had placed the Philippines under martial law, stating he had done so in response to the "communist threat" posed by the newly founded Communist Party of the Philippines (CPP), and the sectarian "rebellion" of the Muslim Independence Movement (MIM). Opposition figures of the time (such as Lorenzo Tañada, Jose W. Diokno, and Jovito Salonga) accused Marcos of exaggerating these threats and using them as an excuse to consolidate power and extend his tenure beyond the two presidential terms allowed by the 1935 constitution. Marcos signed Proclamation No. 1081 on September 21, 1972, marking the beginning of a fourteen-year period of one-man rule, which effectively lasted until Marcos was exiled from the country on February 25, 1986. Proclamation No. 1081 was formally lifted on January 17, 1981 by Proclamation No. 2045, although Marcos retained essentially all of his powers as dictator until he was ousted in February 1986.

This nine-year period in Philippine history is remembered for the Marcos administration's record of human rights abuses, particularly targeting political opponents, student activists, journalists, religious workers, farmers, and others who fought against the Marcos dictatorship. Based on the documentation of Amnesty International, Task Force Detainees of the Philippines, and similar human rights monitoring entities, historians believe that the Marcos dictatorship was marked by 3,257 known extrajudicial killings, 35,000 documented tortures, 737 enforced disappearances, and 70,000 incarcerations. After Marcos was ousted, government investigators discovered that the declaration of martial law had also allowed the Marcoses to hide secret stashes of unexplained wealth that various courts later determined to be "of criminal origin".

A death squad is an armed group whose primary activity is carrying out extrajudicial killings, massacres, or enforced disappearances as part of political repression, genocide, ethnic cleansing, or revolutionary terror. Except in rare cases in which they are formed by an insurgency, domestic or foreign governments actively participate in, support, or ignore the death squad's activities.

Death squads are distinguished from assassination groups by their permanent organization and the larger number of victims (typically thousands or more) who may not be prominent individuals. Other violence, such as rape, torture, arson, or bombings may be carried out alongside murders. They may comprise a secret police force, paramilitary militia groups, government soldiers, policemen, or combinations thereof. They may also be organized as vigilantes, bounty hunters, mercenaries, or contract killers. When death squads are not controlled by the state, they may consist of insurgent forces or organized crime, such as the ones used by cartels.

The Detenidos Desaparecidos (Disappeared Detainees) of state terrorism in Argentina are victims of forced disappearance before, during, and after the last civic-military dictatorship in Argentina, the National Reorganization Process, from 1976 to 1983. Held in clandestine detention centers, they were subjected to torture and, in many cases, killed. The first disappearances and clandestine detention centers began in 1975 under the constitutional government of Isabel Perón and continued until 1984 during the constitutional government of Raúl Alfonsín.

Declassified U.S. government documents from 2006 reveal that a Chilean intelligence agent reported in a 1978 cable to his superiors that Argentine military personnel from Battalion 601 estimated they had killed or disappeared approximately 22,000 people between 1975 and mid-1978. Around the same time, according to these documents, the then-U.S. ambassador in Buenos Aires, Robert Hill, stated: "It is our estimate that at least several thousand were killed, and we doubt it will ever be possible to establish a more specific figure."
