A vigilante calling herself Diana​ the Hunter (Diana la Cazadora) claimed credit in a series of communiques for the slaying of two bus drivers last week in northern Mexico's Ciudad Juárez, saying the killings were revenge for sexual abuse of women by night-shift drivers. "I and other women suffered... but we can't stay quiet," one of the e-mails said. "I am the instrument of vengeance for several women." Witnesses to the first killing Aug. 28 said a black-clad woman with a blonde wig or dyed hair approached the  driver, took out a pistol, shot him in the head and left the bus. The same killer told the second victim before dispatching him, "You guys think you're real bad, don't you?" The targeted bus line brings many women back and forth from the maquiladoras that ring Ciudad Juárez.

Tens of thousands took to the streets across Colombia last week, as workers and students joined the strike launched by campesinos in the north of the country. Violent clashes were reported Aug. 29, primarily from Bogotá, where police fired tear gas into a crowd of some 10,000 assembled in the city's main square, Plaza Bolívar. Witnesses report that despite a strong police presence, the demonstrators remained calm for several hours, with speakers encouraging peaceful protest—until a group arrived (possibly agents provocateurs) who began throwing firecrackers and debris at the police line, sparking the melee. Within 15 minutes, the square had been cleared, though clashes with the ESMAD riot squad continued in the streets surrounding the plaza. Some 20 were injured in the street fighting. Riots were also reported in Soacha, a working-class city on the outskirts of Bogotá, where dozens of masked men clashed with riot police, prompting local authorities to order a curfew.

At least 47 are dead following what appears to have been an Iraqi military assault on Camp Ashraf, a refugee settlement inhabited by exiled members of the People's Mujahdeen Organization of Iran (PMOI), or Mujahedeen Khalq. According to official reports, residents attempted to storm an army post at the entrance to the camp, prompting troops to open fire. PMOI said the post was stormed after the army fired mortar rounds on the camp. PMOI also accused Iraqi forces of executing at least five camp residents—after they had been subdued and hand-cuffed. (NYT, NBC, PMOI, Sept. 1)

Members of the Human Rights Commission of Bolivia's lower-house Chamber of Deputies announced Aug. 30 that they will visit three indigenous leaders from the contested Isiboro Sécure National Park and Indigenous Territory (TIPNIS), who for weeks have refused to leave the remote rainforest reserve to avoid being arrested by National Police troops. Leaders Fernando Vargas, Adolfo Chávez and Pedro Nuny have been maintaining a vigil at the office of the TIPNIS Subcentral of the Indigenous Council of the South (CONISUR) since orders were issued for their arrest on charges related to a supposed attack on a rival CONISUR leader, Gumercindo Pradel. The three wanted leaders charge the government of President Evo Morales with attempting to divide the organization to undermine resistance to a planned highway through the reserve. (ANF, Aug. 30; NACLA, Aug. 27)

Indigenous and environmentalist protesters clashed with police in Ecuador Aug. 27, as a mobilization dubbed a zapateo (foot-stamping) against plans to open the Yasuni Amazon reserve to oil drilling was held in both Quito and Cuenca. Carlos Pérez, leader of the ECUARUNARI indigenous alliance, said police fired rubber bullets on protesters in Quito, leaving 12 hurt—claims denied by the Interior Ministry. At the capital's Plaza de la Independencia, protesters were confronted by an organized counter-demonstration made up of supporters of the ruling Alianza PAIS. After the march, protesters held a public assembly in the city's Plaza Bolívar, where they agreed to meet every Thursday outside the Environment Ministry in an ongiong campaign until their demands are met. The movement is demanding a consulta popular—public discussion and referendum—on the fate of Yasuni. Ecuador's National Assembly is currently considering President Rafael Correa's proposal to open oil blocs within the reserve. (El Universo, Guayaquil, Aug. 29; AFP, Aug. 28)

Less than a year before Colombia's 2014 elections, the country's Supreme Court ordered the arrest Aug. 29 of a presidential primary candidate for former President Alvaro Uribe's Democratic Center party. Luis Alfredo Ramos, former senator and governor of Antioquia,  is under investigation for suspected ties to paramilitary groups—the latest elite figure to be linked to the "para-politics" scandal. Judicial authorities are probing Ramos' purported collaboration with Freddy Rendón AKA "El Aleman"—a now "demobilized" commander of the United Self-Defense Forces of Colombia (AUC). Ramos is also suspected of links to Juan Carlos Sierra AKA "El Tuso"—another AUC commander now imprisoned in the US on drug trafficking charges. "El Tuso" is reported have made major contributions to Ramos' political campaigns. Ramos is expected to be arrested imminently.

Mexican army troops on Aug. 27 disarmed members of the "community police" force after a brief scuffle on the coastal highway in Guerrero state. Some 800 members of the self-defense patrol and their supporters were marching from the pueblo of El Paraíso, Ayutla de los Libres municipality, to  Cruz Grande, Florencio Villareal municipality, when approximately 200 troops in armored vehicles surrounded them, and demanded they surrender their rifles and machetes. In a few minutes of physical struggle, some 300 patrol members were disarmed, and 10 detained. Women, children and elders also participated in the march, which was called to demand liberty for movement leader Nestora Salgado García and 13 "community police" members from Olinalá pueblo.

Canada-based Kinross Gold is said to be rethinking plans for expansion of its massive open-pit mine at Tasiast, Mauritania, after a strike shut the facility for 10 days this month. Amid the shut-down, rating experts at the Bank of Montreal downgraded Kinross and removed the expansion of the Tasiast mine from production forecasts for the company. Some 1,500 workers, representing 98% of the labor force at the mine, walked off the job Aug. 8, demanding better health coverage and respect for Mauritania's labor code. The conflict seems to have begun when managers demanded the mine remain in operation during the Muslim holy day of Eid al-Fitr. The strike, called by Mauritania's main trade union confederation, the CGTM, was resolved Aug. 19 under terms that were not made public. The International Trade Union Confederation (ITUC), with which the CGTM is affiliated, is demanding "urgent clarification" on the fate of one worker for subcontractor Canary Log, allegedly found dead under "obscure circumstances" near the mine site during the strike.
