Prosecutors in Brazil have opened an investigation after reports that illegal gold-miners on a remote Amazon river massacred at least 10 members of an "uncontacted" indigenous band. If confirmed, this means up to a fifth of the entire band have been wiped out. Two gold-miners have been arrested in the case. The killings allegedly took place last month along the Rio Jandiatuba in the Vale do Javari Indigenous Territory, a huge area  in Amazonas state bordering Peru. The region is known as the "Uncontacted Frontier," as it shelters more isolated peoples than anywhere else on Earth. Reports of the massacre only emerged after the miners started boasting about the killings, showing off "trophies" in the nearest town.

Colmbia's highest judicial body, the Fiscalía General, has opened investigations into the slaying six demobilized FARC fighters and nine family members of demobilized guerillas in apparent reprisal attacks since the peace accord took effect late last year. The attacks took place in the departments of Caquetá, Antioquia, Putumayo, Tolima, Cauca and Valle del Cauca. (El Espectador, July 27) But the wave of deadly attacks on social leaders across Colombia has also persisted, in spite of the peace process. Human rights group Global Witness, which annually releases a report on the world's most dangerous countries for environmental defenders, this year names Colombia as second only to Brazil. The group counts 37 environmental activists slain in Colombia in 2016, compared to 26 in 2015. In the first six months of 2017, the figure was already up to 22. (El Colombiano, July 19)

Tens of thousands of Argentines held protests across the country Sept. 1, demanding answers one month after the disappearance of an indigenous rights activist. Demonstrators held photos of Santiago Maldonado, who was last seen when border police evicted a group of indigenous Mapuche from lands in the southern Patagonia region owned by Italian clothing company Benetton. In Buenos Aires, protesters converged on the Plaza de Mayo, iconic for its role in the struggle to demand justice for the "disappeared" under the military dictatorship. The Buenos Aires march ended in running street battles with the riot police.

Israeli authorities have revoked the citizenship of hundreds of Bedouin Palestinians in the Negev desert in recent years, leaving many stateless and without recourse to appeal the decision. Since the establishment of Israel in 1948 the Bedouin community has faced policies of dispossession and displacement. More than half of the 160,000 Bedouin in the Negev live in "unrecognized" villages, leaving them deprived of water, electricity and other basic infrastructure. In recent years, Israeli authorities have started revoking the citizenship of Bedouin residents, according to a new report in Haaretz newspaper.

Cambodia's National Assembly on July 10 passed a bill which prohibits political parties from being affiliated with convicted criminals. Commentators believe the law is aimed at weakening the opposition Cambodia National Rescue Party (CNRP). The CNRP's former leader, Sam Rainsy, recently resigned from the party after he was sentenced to two years in prison on defamation charges. As a result of the new law, Rainsy will no longer be able to be affiliated with the CNRP in any manner. The CNRP gained significant political strength in the 2013 Cambodian elections when the party took a total of 55 seats in the National Assembly, leading many to believe the defamation charges against Rainsy were politically motivated.

Protesters blocked the train line to the Inca archaeological site of Machu Picchu, stranding thousands of tourists during a 48-hour paro (civil strike) by residents of Peru's Cuzco region. British-owned PeruRail company announced that service was suspended July 13-4 because of the blockades. At issue is a planned new airport for the Cuzco area, that was suspended in March due to controversies surrounding the construction contract. The airport—slated for Chinchero Valley, to the north of Cuzco's capital in neighboring Urubamba province—has now been pushed back until 2020. Local residents were eager for the region's first intercontinental airport to boost tourism revenues, and as a symbol of autonomy from Lima. Constantino Sallo, president of the Defense Front for the Interests of Chinchero District, demanded the government set a timetable of between 90 and 120 days to break ground on the project.

After an all-night negotiating session with protest leaders in Colombia's Pacific port of Buenaventura June 5, government representatives pledged to invest $517 million in local infrastructure in return for a lifting of the civic strike that has rocked the region for weeks. Despite a curfew, confrontations had continued in the port city between residents and the feared National Police riot squad, ESMAD. On the night of May 31, clashes with ESMAD troops again filled the streets with tear-gas. Protesters continued to call on President Juan Manuel Santos to follow through on his promises of new schools, housing, hospitals and potable water for the long-neglected Pacific coast region. The strike primarilly impacted the adjacent departments of Valle del Cauca, where Buenaventura is located, and Chocó to the north. (TeleSur, Colombia Reports, June 6; El Espectador, May 31)

After a near-breakdown in Colombia's peace process last month, Colombia's government is scrambling to revive the disarmament and demobilization of the FARC guerillas—under pressure from a citizen mobilization. The popular networks Marcha Patriótica and Congreso de los Pueblos joined on June 1 for a youth demonstration in support of the peace process, with some 600 holding vigil in downtown Bogotá. (El Espectador June 1; Contagio Radio, May 31) A new deadline of June 20 has now been set for FARC fighters to turn over all their weapons. UN monitors and the FARC say that 30% of the arms have now been handed over to the UN team overseeing the disarmament. (BBC News, June 8; El Espectador, May 30)
