By a unanimous vote, on Oct. 24 Chile's Supreme Court of Justice overturned the convictions of two young Mapuche prisoners for the attempted homicide of Gen. Iván Besmalinovic, a commander of the carabineros militarized police, in November 2011. The two prisoners had been on a liquids-only hunger strike along with two other Mapuche prisoners since Aug. 27 in the city of Angol in the southern region of Araucanía. After receiving word of the court's decision, the hunger strikers met with members of their home community, Wente Winkul Mapu, and on Oct. 25 they decided to end their fast.

Thousands marched in Santiago on Oct. 15 to demand respect for the rights of Chile's indigenous peoples—the Mapuches in the south, Aymara speakers in the north, and the Pascuenses (Rapa Nui) of Easter Island. The march, sponsored by the Meli Wixan Mapu Organization, the José Guiñón communities, the community of Wente Winkul Mapu and the Temukuikui Autonomous Mapuche Community, also demanded the release of four Mapuche prisoners who had been on hunger strike in the southern city of Angol for 50 days. Media estimates for participation ranged from 3,000 to 7,000.

Five prisoners from Chile's indigeous Mapuche group began a hunger strike on Oct. 1 in the city of Temuco in the southern Araucanía region, joining four Mapuche prisoners who have been on hunger strike in Angol, also in Araucanía, since Aug. 27. The Temuco strikers—Leonardo Quijón Pereira, Luis Marileo Cariqueo, Fernando Millacheo, Guido Bahamondes and Cristian Levinao--said they were protesting the conspiracy by the "state, the business owners and the large landowners to use the laws against us to keep us far from our families and loved ones." The prisoners are asking to be moved to the Angol prison, which is closer to their homes, and are calling on the government to end the "humiliating and annoying searches the Gendarmerie of Chile [the prison authorities] carries out on relatives and friends who visit us in the prison."

Members of the Huilliche indigenous group blocked the highway between Valdivia and Paillaco in southern Chile's Los Ríos region the morning of Sept. 28, burning rubbish and setting up barricades to protest a Sept. 21 Supreme Court decision denying them access to a sacred site. A communiqué from an organization calling itself the Huilliche Aynil Leufu Mapu Mo Resistance claimed responsibility for the action, which was also in support of a hunger strike that five Mapuche prisoners in Angol, Araucanía region, began on Aug. 27. The Huilliche are a sub-group of the Mapuche, the largest indigenous group in Chile.

The Sept. 11 anniversary of Chile's 1973 coup exploded into a night of street battles in Santiago that ended with one officer of the Carabineros dead, 26 people wounded, and 255 arrested, including 83 minors. Five public buses were set on fire to make street barricades, and more than 400 others sustained broken windows and other damage, prompting the transportation agency to shut service throughout the city. There was widespread looting through the night, and at least 58,000 homes were left without power after hooded protesters threw metal chains onto power lines. The Carabineros officer was apparently killed when he tried to stop the looting of a supermarket in the northern district of Quilicura.

As of Aug. 31 six Mapuche activists were on hunger strike to protest what they consider the Chilean government's repression of struggles by the indigenous group, the country's largest. The strikers include five prisoners in Angol, in the southern region of Araucanía, and Pascual Catrilaf, a machi (healer and spiritual authority) who lives in Temuco, also in Araucanía. A seventh striker, Mewlen Huencho, a werkén (spokesperson) for the Mapuche Territorial Alliance, ended her six-day fast at the Santiago offices of the United Nations Children's Fund (UNICEF) after speaking to UNICEF officials on Aug. 31.

A Brazilian federal judge in Pará on Aug. 31 agreed to conduct the first trial against members of the former dictatorship for alleged crimes during the military's rule from 1964-1985. The defendants are two retired army reserve members, Col. Sebastiao de Moura and Maj. Licio Maciel, accused of kidnappings during suppression of the guerilla movement in the Araguaia region between 1972 and 1975. The judge agreed with prosecutors that Brazil's 1979 amnesty law, which provides amnesty for members of the government and military alleged to have committed political crimes between 1961 and 1975, does not apply because bodies of the alleged kidnapping victims were never found, and the cases are therefore still technically open.

A Brazilian federal judge on Aug. 23 ruled that permits for more than 120 proposed hydro-electric dams in the Upper Paraguay River Basin cannot be issued without first conducting environmental impact assessments, dealing a blow to a major thrust of development planned for the states of Mato Grosso and Mato Grosso do Sul. The ruling comes in response to a request from state and federal prosecutors in Mato Grosso do Sul, who petitioned the 1st Federal Court in Coxim for an injunction suspending construction of 126 new dams in the Pantanal, a vast region of wetlands in the basin. The ruling also impacts 20 already operating hydro plants, which will be able to continue running under their current licenses, but must submit to an impact study before seeking license renewals. Utilities must seek approval for the studies from the Brazilian Institute for the Environment and Natural Resources (IBAMA) as well as state authorities before the projects can move ahead.
