A wave of student protests demanding education reform in Chile has been met with harsh repression, leading to charges of "torture" recalling the era of military rule. Clashes with police during President Michelle Bachelet's state-of-the-nation addres in Valparaiso made English-language headlines May 21. Demonstrators set up barricades and hurled fire-bombs, torching a pharmacy and supermarket, while police fired tear-gas and water cannon. A security guard reportedly died from smoke inhalation. Three days later, protesters actually invaded the presidential palace in Santiago, forcing their way past guards. Winning few headlines outside Chile is the controversy over abuse of arrested protesters. Most egregious is the case of Roberto Zambrano Freire, 18, who was arrested at a protest outside the National Institute, the country's most prestigious school, on May 17 and apparently beaten after being made to strip naked while in custody. The student's father, Roberto Zambrano Sepúlveda, says he is pressing for an investigation but is not optimistic, noting that "It is my boy's word against the Carabineros." He added: "The Carabineros of Chile continue operating with the same methods as the under the dictatorship." (TeleSur, BBC News, Diario UChile, BiobioChile, La Tendencia, RPP, Univision)

The UN Commission on the Limits of the Continental Shelf (CLCS) ruled on March 28 that Argentina's maritime territory includes the area surrounding the Falkland Islands. Argentina had previously submitted to the commission a report fixing the territory at 350 [nautical] miles from its coast instead of 200. The commission made clear that it was not in a position to consider and qualify parts of the submission that are subject to dispute. The commission's findings expand the maritime territory of Argentina by 35%. Susana Malcorra, Argentina's foreign minister, maintained that the findings reaffirm the country's sovereignty rights over the resources of its continental shelf. The findings have been dismissed by the UK as recommendations that are not legally binding.

President Obama's visit to Argentina this week coincided with the 40th anniversary of the 1976 military coup that opened the country's "Dirty War," in which thousands of leftist dissidents were killed or "disappeared" during a seven-year dictatorship. Obama made note of the occassion, joining with Argentine President Mauricio Macri to visit the Monument to the Victims of State Terrorism at Remembrance Park in Buenos Aires. But the visit was boycotted and protested by some advocates of justice for the "Dirty War" victims. "We will not allow the power that orchestrated dictatorships in Latin America and oppresses people across the world to cleanse itself and use the memory of our 30,000 murdered compatriots to strengthen its imperialist agenda," said a statement by Myriam Bregman of the Center for Human Rights Professionals and other advocates. Nora Cortiñas of the Mothers of the Plaza de Mayo said: "I lament that Marci has accepted that the executive of the United States come during these days. It is inappropriate, a provocation."

In Brazil's biggest protests since the end of the military dictatorship in 1985, thousands have poured into the streets in cities cities across the country to denounce President Dilma Rousseff's appointment of her predecessor and political mentor, Luiz Inacio "Lula" da Silva, as chief of staff. Days of nationwide demonstrations reached a climax as Lula was sworn in on March 17. In Brasilia, riot police fired pepper spray to disperse protesters who massed outside the presidential palace, chanting "Dilma out!" Demonstrators say Rousseff transparently appointed Lula in order to give him immunity as he comes under investigation in a corruption scandal at the state oil company Petrobras.

Argentine lawyer and federal prosecutor Alberto Nisman was the victim of murder according to Criminal Appeals Court Prosecutor Ricardo Sáenz in a Feb. 25 decision. The declaration is the first time a judicial authority has suggested the death as a homicide since the mysterious tragedy in January 2015. Sáenz recommended that the case be handed to federal authorities and investigated as a murder. The prosecutor wrote that he agreed with the assassination theory that Nisman's family presented in a complaint to the appeals court in Buenos Aires and that all the evidence points to Nisman's death as a murder, not a suicide. Judge and Nisman's former wife, Sandra Arroyo Salgado, also maintains that the case be handed over to federal authorities in order to fulfill their role as the country's institution for investigating the suspicious death of a public servant. The court will evaluate Sáenz's findings on March 18.

Riot police fired rubber bullets and tear-gas at protesting public-sector workers recently laid off by budget cuts in Argentina's La Plata municipality on Jan. 8, with several left wounded. The workers were protesting a decision by local mayor Julio Garro that canceled 4,500 contracts on Dec. 31. The country's new right-wing President Mauricio Macri's administration has laid off 10,000 public-sector workers since the beginning of 2016. In his one month since taking office, he has signed 29 Necessity and Urgency Decrees (DNUs) intended to institute structural reform and reverse the legacy of his center-left predecssor  Cristina Fernández de Kirchner. The mass lay offs have affected workers throughout Argentina and more are expected.

Brazil's Minster of Natural Environment said Nov. 27 that the country's government plans to sue BHP Billiton Ltd., Vale SA, and Samarco Mineração SA for $5.24 billion for damages caused by a dam collapse at an iron ore site the two co-own. The iron ore site, Samarco Mineração SA, is a joint mining venture between the two companies. BHP Billiton Ltd. is the largest mining company, and Vale SA is the biggest ore miner in the world. The dam contained and released 60 million cubic meters of mine waste and mud that killed at least 13 people, left approximately 11 people missing, and devastated an entire village when it collapsed earlier this month. Brazilian Minister Izabella Teixeira announced that the government would seek to create a fund to compensate victims and to pay for the environmental recovery of the effected areas. The fund would be created gradually as a percentage of the companies' profits. The Special Rapporteurs sent by the UN Office of the High Commissioner for Human Rights (OHCHR) reported  that the "steps taken by the Brazilian government, Vale and BHP Billiton to prevent harm were clearly insufficient" and that "this disaster serves as yet another tragic example of the failure of businesses to adequately conduct human rights due diligence to prevent human rights abuses." 

Brazilian mining company Samarco has agreed to pay at least $260 million in compensation for the Nov. 11 collapse of two dams it used to hold waste water from iron ore, which caused an avalanche of mud to inundate nearby villages in Minas Gerais state. Eleven people were killed and 12 are missing, presumed dead. The village of Bento Rodrigues was totally destroyed, with more than 500 people left homeless. Residents are being temporarily housed in hotels in the city of Mariana. Some 250,000 local residents are also left without drinking water. The mud is still being tested for potential toxins from the mine. In imposing the fine, Brazilian environmental agency IBAMA called the disaster "the worst mining accident in Brazil's history." Operations at the facility remain suspended, with Samarca admitting that two more dams at the site are "at risk of collapsing."
