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. 

Argentina's state firm YPF was at the point of completely shutting down oil and gas production throughout Neuquén province after indigenous Mapuche residents blocked access to to wells for 48 hours to press demands over territorial rights. The blockades were lifted Sept. 4 after a hectic days of dialogue with Mapche leaders. The blockade was undertaken by the Mapuche community of Paynemil to press authorities to complete a demarcation of traditional indigenous lands in the area, as mandated by National Law 26.160 of 2006 but still not carried out. Hundreds of wells at the Loma La Lata, Rincón del Mangrullo and Loma Campana fields were affected by the action, supposedly costing YPF millions of dollars. July saw similar protests, when the Loma Campana field was blocked by members of the Mapuche community of Campo Maripe. The issue has been outstanding for years, but the new blockades marked the first time that hydrocarbon production throughout the province was affected. (InfoBae, InfoBae, Cronista, Sept. 4; Cronista, Diario Norte, July 30)

In new protests over the Bloc 192 oil-field in the north Peruvian Amazon, some 20 indigenous Achuar and Kichwa warriors occupied the local air-strip of multinational Pluspetrol, in Trompeteros, Loreto region. They also seized a pumping station at nearby Pavayacu. The protesters are demanding better compensation for the use of their lands, and opposing the new contract for development of the field to Canadian company Pacific Stratus Energy, a subsidiary of Pacific Rubiales. A civil strike was also declared in Iquitos, the region's principal city, where barricades were built on major streets, paralyzing traffic. The Iquitos protesters, supported by the region's president, want the oil bloc to be taken over by state-owned PetroPeru. "The only thing foreign companies have done is pollute and foment distrust among local populations," said Loreto president Fernando Meléndez. "We don't see any benefits and remain an impoverished region." The bloc has been exploited for more than 40 years, most recently by Pluspetrol, an Argentine company whose contract expired Aug. 29. The 48-hour paro or civl strike was jointly called by Loreto Patriotic Front (FPL) and the Federation of Native Communities of Alto Tigre (FECONAT). (TerraPeru, Sept. 3, La República, Reuters, Sept. 2; El Comercio, Peru21, Sept. 1; Andina, Aug. 21)

The ongoing dilemmas over Palestinian statehood took a new turn this week as the Vatican objected to a Palestinian Authority request for the two observer states to the United Nations to be allowed to raise their flags at its headquarters. The Palestinian leadership called on the UN to adopt a resolution approving the raising of the Palestinian and Vatican flags alongside those of the member states. In an Aug. 28 statement, the Holy See said it would abide by any resolution, but noted that since the its founding in 1945, it has been a tradition that "only flags of member States are displayed at the UN headquarters and offices." The statement seems to be aimed at placating Israel, which harshly criticized the Vatican in June after it formally recognized a Palestinian state, signing its first bilateral accord with the Palestinian Authority, concerning the activities of the Church in the Palestinian territories. A vote on the flag resolution, sponsored by 21 countries, is to take place Sept. 15. Among the co-sponsors are Saudi Arabia, Egypt, Algeria and Jordan. An Israeli Foreign Ministry official dismissed the resolution as a "cheap and unnecessary gimmick."

Iran's regime on Aug. 26 hanged Kurdish political prisoner Behrouz Alkhani at Orumieh prison, in the country's west. The death sentence was carried out two days after more than 80 members of his family and human rights activists gathered outside the prison gates to demand a halt to his execution. Prison guards and anti-riot forces broke up the protest. Alkhani's execution took place even as Iran's Supreme Court had yet to respond to an appeal of his sentence. "Carrying out a death sentence while a prisoner is awaiting the outcome of his appeal is a serious violation of both Iranian and international law, and is an affront to justice," said Said Boumedouha of Amnesty International's Middle East program.

Protesters cut off access to the Bolivian mining city of Potosí for most of last month in a dispute with the central government over infrastructure investment. Access to the city of more than 130,000 was blocked by thousands of protesters as part of a civil strike called by the Comité Cívico Potosinista (COMCIPO). The strike was "suspended" after 27 days on Aug. 2, when the city had almost run out of petrol, food and money. But organizers declared President Evo Morales and his cabinet members "enemies of Potosí" and "persona non grata" throughout the department. They also called for the resignation of the city's mayor, William Fernández, and the departmental prefect, Juan Carlos Cejas, both from Bolivia's ruling Movement Toward Socialism (MAS).

Independent aid group Medecins Sans Frontieres (MSF) reported Aug. 25 that it had treated four members of a Syrian family who suffered from breathing difficulties and developed blisters after a mortar hit their home in Marea, Aleppo governorate. The Syrian American Medical Society also reported receiving 50 patients showing symptoms of chemical exposure in the same area. Local rebels said the shells were fired from an ISIS-held village to the east. A spokesman for one rebel group, the Shami Front, told the New York Times that half of the 50 mortars and artillery rounds that hit Marea contained sulphur mustard. The powerful irritant and blistering agent —commonly known as "mustard gas" but actually liquid at ambient temperature—causes severe damage to the skin, eyes and respiratory system.
