On March 13 the Bolivian government declared three days of mourning for union and leftist leader Domitila Barrios de Chungara, who died of lung cancer at her home in Cochabamba earlier that day. Born into a mineworkers' family in 1937, Barrios de Chungara started her political work in a women's auxiliary for the mineworkers union in the Siglo XX mining district and eventually became a prominent union leader. In 1978 she initiated the mass hunger strike that resulted in the collapse of the 1971-1978 dictatorship of Col. Hugo Banzer Suárez and the restoration of formal democracy.

In a surprise move on March 13, agents of Peru's National Police arrested three leaders of the struggle against the controversial Conga gold mining project in the northern region of Cajamarca, while charges were announced against some 40 others. Wilfredo Saavedra Marreros, leader of Cajamarca's Environmental Defense Front, was detained in the southern city of Tacna, where he had been invited to speak by student groups. Nearly simultaneoulsy in Cajamarca, police agents arrested Lucio Díaz Chávez, former regional president of the teachers union SUTEP, and César Tafur Tacilla, secretary general of the local construction workers union. Saavedra was taken in police custody to Cajamarca, where he was freed the next morning along with Díaz and Tafur. All three are charged with obstruction of public transport in connection with last year's protest mobilization against the Conga mine, and await orders to appear before a judge. The next day, the Cajamarca branch of the Fiscalía, Peru's attorney general, released a list of 41 activists facing identical charges—including virtually all the prominent leaders of the Cajamarca protest movement.

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.

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.
