Residents of San Juan Jáchal, in Argentina's northwestern province of San Juan, took to the streets in protest after an industrial malfunction caused a pipe carrying cyanide to Barrick Gold's nearby Veladero gold mine to rupture and spill an undetermined amount of its contents in the area on Sept. 13. Protesters who converged on the town hall said town residents had repeatedly warned on social media and through text messages to authorities that the pipe had a faulty valve—and that no move to address the problem was taken even after messages reported that spills had reached the banks of the Río Jáchal. The river is the source of water for the town, and municipal taps have been cut off since the spill. (MercoPress, InfoBae, Sept. 16; Reuters, InfoBae, Sept. 14)

Without fanfare in either country, some 3,000 US troops are now arriving in Peru for an anti-drug "training mission." The troops embarked, along with several cargo planes, on the USS George Washington Sept. 1—sparking street protests in Lima. Thousands filled downtown Lima chanting slogans against the "Yankee terrorists," and several US flags were burned. Ex-congressman Gustavo Espinoza decried what he called a "military invasion." He suggested that the US had ulterior motives behind the mobilization: "What is looming is a sort of 'sting operation'...designed to enhance the North American presence not only in Peru but in the Americas... The Empire seeks to change the correlation of forces now in place in the region." (HispanTV, Sept. 2; TeleSUR, Sept. 1)

The latest edition of the English-language ISIS magazine Dabiq, released online Sept. 9, contains the predictable parade of perversions. Two men, Norwegian and Chinese nationals, are offered for sale as slaves. The destruction of ancient temples at the Palmyra archaeological site is trumpeted. Child soldiers are glorified as "lion cubs" of the "caliphate." The 9-11 attacks are hailed as the "blessed operations." But it also features an interview with Abul Mughirah al-Qahtani, identified as the "delegated leader" of the Islamic State's Libyan "province," in which he harshly criticizes several rival jihadist outfits, including Ansar al-Sharia, the Abu Salim Martyrs Brigade (ASMB), the Libyan Islamic Fighting Group (LIFG), and the Libyan Dawn coalition.

India's National Investigation Agency (NIA) on Sept. 3 announced a Rs 7 lakh (approx. $10,500) bounty on Naga insurgent leader SS Khaplang in connection with an attack on an army convoy in Manipur three months ago that killed 18 soldiers. The 75-year-old rebel heads the National Socialist Council of Nagaland-Khaplang (NSCN-K), that has long waged an armed struggle for an independent Naga homeland uniting parts of Manipur, Arunachal Pradesh and Assam states along with areas of Burma. In early August, India's central government signed a peace agreement with the rival NSCN-IM (Isak-Muivah, named for leaders Isak Chisi Swu and Thuingaleng Muivah). But the Khaplang faction is not yet recognizing the accord, and the bounty appears to signal Delhi's impatience—or a strategy to keep the Naga struggle divided.

Ecuador's Secretary of Communications (Secom) on Sept. 8 officially informed the free-speech advocacy organization Fundamedios that it is being dissolved for promoting "indisputably political" material, in violation of the country's Unified Information Regulatory System for Social Organizations (RUOS). The case rests on Fundamedios linking on its Twitter feed to material critical of President Rafael Correa and his government—especially from the blogs Estadodepropaganda.com and SentidoComunEcuador.com. The organization has 10 days to appeal, but Fundamedios director César Ricaurte said he has little faith in the process, calling the announcement "A chronicle of a death foretold."

The constitutional chamber of El Salvador's Supreme Court of Justice on Aug. 24 ruled that the country's notoriously violent street gangs and those who support them financially will now be classified as "terrorist groups." The ruling came in a decision rejecting four challenges to the constitutionality of the country's Special Law Against Terrorist Acts (LECAT). The ruling defines terrorism as the "organized and systematic exercise of violence," placing the label on any group that attempts to usurp the state's monopoly on use of force. The ruling upholds the freezing of funds for any persons believed linked to the named groups, and a ban on any negotiation with the groups. At issue are the rival Mara Salvatrucha and Barrio 18 gangs.

Venezuelan President Nicolas Maduro on Aug. 21 indefinitely closed a busy border crossing with Colombia and declared a 60-day state of emergency in several nearby towns after three soldiers were shot and wounded in an apparent clash with smugglers. Authorities said two assailants on a motorcycle fired on a patrol in the border town of San Antonio del Táchira, wounding a civilian as well as the two army lieutenants and a captain. Maduro has mobilized some 15,000 troops the area, and says the Simon Bolívar International Bridge, over the Río Táchira that forms the border, will remain closed until the assailants are apprehended. Colombian President Juan Manuel Santos has protested the border closure, signaling another flare-up between the uneasy South American neighbors.

A Guarani-Kaiowa indigenous leader was shot dead Aug. 29 at Douradina municipality in Brazil's Mato Grosso do Sul state, one week after his community occupied part of their ancestral lands. Community leaders had warned of an imminent attack, after their encampment was surrounded by gunmen in 30 vehicles. Semião Vilhalva of the Nanderu Marangatu community was killed when the gunmen, hired by local ranchers, finally stormed the encampment—reportedly in the presence of government agents. The encampment was re-established after the attack, but suffered a second assault on Sept. 3. "They came in and began to shoot everywhere," said one Guarani leader.
