Some 1,500 to 2,000 protesters demonstrated against the Rio de Janeiro state government and militarized police the evening of July 22, the first day of Pope Francis' weeklong visit to Brazil. The protest, reportedly called by the anarchist groups Anonymous Rio and Anonymous Brazil, started as Francis, on his first international trip since he took office in March, was meeting with Brazilian president Dilma Rousseff and Rio state governor Sérgio Cabral in the Guanabara Palace, the state's main administrative building, in the city of Rio de Janeiro. Shortly after the pope left the meeting, someone hurled a molotov bomb at line of police agents, who responded with tear gas and water cannons. Two agents were injured by the bomb, and other people were hurt in the melee that followed, including a photographer from the Agence France-Presse wire service.

Indigenous communities in Arauco province in Chile's central Biobío region have announced plans for a march on Aug. 2 to protest a proposal before the National Congress to extend Forestry Decree 701 for another 20 years. Community residents, who belong to the Mapuche group, Chile's largest ethnicity, say the forestry laws have allowed timber companies to take over traditional Mapuche lands starting in 1974 under the 1973-1990 dictatorship of Gen. Augusto Pinochet. The most important of these companies are Arauco (Celulosa Arauco y Constitución), largely owned by the Angelini family, and Forestal Mininco, controlled by the Matte family. According to Mapuche activists, there is little chance that the forestry proposal will be defeated, since many of the congressional candidates from Mapuche areas in the upcoming Nov. 17 elections are being financed by these two powerful families.

Indigenous Mapuche occupied four oil wells in the Vaca Muerta region in the southwestern Argentine province of Neuquén on July 16 to protest a $1 billion agreement between the state-controlled Yacimientos Petrolíferos Fiscales (YPF) oil company and the California-based Chevron Corporation to drill for oil in the area's shale deposits. (In an earlier item we wrote erroneously that the drilling was for natural gas.) The Mapuche say that the drilling, which uses the controversial method known as hydrofracking, will damage the local environment, and that the agreement was made without the required prior consultation with the indigenous communities. The protesters were also expressing solidarity with indigenous Ecuadorians who won a $19 billion judgment in 2011 against Chevron for environmental damage. The company refuses to pay.

On July 14 the three-member Appeals Court of Copiapó province in Chile's northern Atacama region unanimously upheld its April 10 order suspending work at Toronto-based Barrick Gold Corporation's Pascua Lama mine until the company has adopted measures to repair current damage to the environment and to prevent further damage in the future. The court found that in its responses to the previous order the company "repeatedly" displayed "an obstinate attitude" and that it "doesn't provide information on time and in proper form." Pascua Lama is an open-pit gold, silver and copper mine under construction in the Andes on both sides of the border between Argentina and Chile. Five indigenous Diaguita communities had filed a complaint against the mine, charging that the construction had damaged glaciers near the site that provide water for area residents. The mine is also subject to a May 24 suspension ordered by Chile's environmental regulator, Juan Carlos Monckeberg. (Associated Press, July 15, via Terra, Peru)

Tens of thousands of Brazilian workers participated in a one-day general strike in 20 or more cities on July 11, with strikers holding generally peaceful rallies and marches that blocked highways and bridges at dozens of points throughout the country. The strikers' demands included the reduction of the work week from 44 to 40 hours; a speeding up of the agrarian reform program; greater public funding for health and education; control of inflation; and changes in economic policy. The action, the National Day of Struggles, was called by the six main labor confederations, including the Unified Workers Central (CUT), which is affiliated with the center-left Workers Party (PT) of President Dilma Rousseff. The Landless Rural Workers Movement (MST) and the National Students Union (UNE) backed the strike. 

In a press conference on July 11 representatives of Argentina's indigenous Mapuche and of indigenous communities in the Vaca Muerta region in the southwestern province of Neuquén announced plans to block the California-based Chevron Corporation from drilling for natural gas in their territories. In December 2012 Argentina's state-controlled Yacimientos Petrolíferos Fiscales (YPF) oil company signed an agreement for a $1 billion hydrofracking pilot project in the Vaca Muerta area, despite a November decision by an Argentine judge to embargo Chevron's assets in Argentina because of a $19 billion judgment against the company in Ecuador for environmental damage and injuries to the health of indigenous residents in the Amazon rainforest. YPF and Chevron are scheduled to sign an additional accord on July 15; the oil companies deny that the drilling will be on Mapuche lands.

According to declassified British and US documents that the Washington, DC-based research group National Security Archive (NSA) made public on June 25, Israel secretly bought 80-100 tons of Argentine uranium oxide ("yellowcake") in the 1963-1964 period. The uranium ore was purchased to be used as fuel at Israel's Dimona nuclear reactor in the Negev desert and ultimately for producing plutonium for the country's clandestine nuclear weapons program. France had cut off Israel's supply of French uranium, and the Israeli government was looking for new sources, including South Africa and Argentina. The Argentine president at the time was Arturo Umberto Illia (1963-66) of the centrist Radical Civic Union (UCR).

More than 100,000 Chileans marched in Santiago on June 26 in the latest massive demonstration for a system of free secondary and higher education to replace the heavily privatized system created under the 1973-1990 military dictatorship. There were similar protests in cities throughout the country, along with walkouts by port workers in support of the students' demands. In addition to high school and university students, the march drew port workers, teachers, copper miners and municipal health workers.
