Led by the National Confederation of Artisenal Miners (CONAMI), small-scale independent gold miners led strikes and protests across several regions of Peru last week. The southern rainforest region of Madre de Dios was most affected, with regional capital Puerto Maldonado virtually shut down for several days following initiation of the paro (civil strike) on March 5. Thousands of miners filled the streets, wearing helmets and plastic ponchos color-coordinated to represent their geographic zone. Other social movements observed the paro in solidarity, and most businesses shut down. The region's estimated 18,000 artisenal miners—the vast majority of them "informal"—are demanding the aborgation of recent presidential decrees mandating that only legally recognized mining activity will be permitted. Some 3,000 miners are currently camped out in Puerto Maldonado as they await the arrival of a cabinet-level commission led by Environment Minister Manuel Pulgar Vidal and Energy and Mines Minister Jorge Merino to establish a dialogue on "formalization" of the artisenal miners. Luis Otzuka, leader of the Madre de Dios Regional Artisenal Mining Federation (FEDEMIN), said the strike will be maintained until a solution is reached.

On March 5, a special intelligence unit of Peru's National Police announced the arrest of Walter Díaz Vega AKA "Freddy" or "Percy"—said to be the successor of the Shining Path leader "Comrade Artemio," himself captured weeks earlier. Comrade Freddy was apprehended in the hamlet of Alto Alianza, José Crespo y Castillo district, Leoncio Prado province, Huánuco region. The hamlet is in the Magdalena Valley, an arm of the Upper Huallaga Valley, one of two zones of the country where a state of emergency remains in effect due to Shining Path activity. Comrade Freddy, apparently betrayed by infiltrators, was transfered to the National Anti-Terrorism Directorate (DIRCOTE) in Lima for interrogation. The National Police hailed the arrest as a "mortal blow" against the Shining Path.

On Feb. 29 the Superior Court of Colombia's Cundinamarca department upheld a lower court's conviction of journalist Luis Agustín González for "injurias" ("abuse" or "insults") against former governor and senator María Leonor Serrano de Camargo. The court threw out the lower court's conviction of González for libel. The journalist faces a sentence of 18 months in prison and fine of 9.5 million pesos (about $5,450).

Hundreds of relatives and friends of people killed or injured in the crash of an Argentine commuter train on Feb. 22 marched in downtown Buenos Aires the night of Feb. 28 to demand a thorough investigation of the accident and punishment for those responsible. Carrying candles, pictures of the victims and signs describing the commuter trains as "metal tombs," the protesters called for a meeting with President Cristina Fernández de Kirchner. The march ended with a vigil at the Obelisk in the Plaza de la República. (Clarín, Buenos Aires, Feb. 28)

New confrontations broke out in Chile's southern Aysén region on the morning of March 3 when police agents confronted about 100 protesters at barricades residents had set up in the small town of Puerto Ingeniero Ibáñez. Like residents of other parts of the region, protesters in the town had resumed blocking traffic a few days earlier when the government of right-wing president Sebastián Piñera set new conditions for negotiations.

Leaders of the Ngöbe-Buglé indigenous group suspended talks with Panamanian officials and resumed their blockade of the Pan American highway on March 1 after four young protesters were wounded by rubber bullets near the National Assembly building in Panama City. The Ngöbe-Buglé and their supporters had shut down traffic in the western provinces of Chiriquí and Veraguas for more than a week starting on Jan. 30 but lifted the roadblocks on Feb. 7 when the government of rightwing president Ricardo Martinelli agreed to hold talks on their demands to ban all mining and hydroelectric projects from Ngöbe-Buglé territories.

US Secretary of Homeland Security Janet Napolitano on Feb. 28 defended the US-backed war on the drug cartels, despite the growing violence in Mexico and Central America. On a five-day tour of the region, Napolitano insisted in a joint press conference with Mexican Interior Minister Alejandro Poire that the US and Mexico would maintain "a continuing effort to keep our peoples from becoming addicted to dangerous drugs.... It's a different type of crime and it's a different type of plague, but that's also why it is so important that we act not only bi-nationally, but in a regional way, to go after the supply of illegal narcotics."

In an official report, Paraguay's Department of Indigenous Affairs (INDI) confirmed this week that an uncontacted tribe is living on lands in the northern Chaco region owned by a controversial ranching company. Signs of the isolated Ayoreo tribe have been found on lands of the Brazilian firm River Plate. The investigation shows clear signs of the presence of the so-called "hiding tribe"—detailing footprints, holes dug to capture tortoises, and broken branches. INDI warned that the tribe is being "forced to flee to other areas to avoid being discovered." The evidence will have consequences for cattle ranching companies River Plate and BBC SA, which have already been accused of putting the lives of the Ayoreo at risk. Satellite images from 2011 revealed their destruction of almost 4,000 hectares of forest inhabited by uncontacted bands, and led to the companies being charged with illegal deforestation.
