As Venezuela lurches deeper into political crisis, President Nicolas Maduro has announced a new phase in the government's controversial "Operation Liberate the People" security program, pledging to cleanse the country of gang-related crime. Thousands of elite military troops have been deployed across Caracas, with five new "permanent" bases and over 130 checkpoints established in the city. Perhaps not coincidentally, this comes as Maduro has declared a "state of emergency" throughout the country in response to a supposed US-backed conspiracy against him by the political opposition, earning rebukes from Amnesty International, which called the declaration "alarming."

A federal judge in Mexico ruled May 9 that drug lord Joaquín "Chapo" Guzmán may be extradited to the US—where he faces numerous federal charges of drug trafficking, kidnapping, money laundering and murder in Chicago, Miami and New York. Mexico's Exterior Secretariat has 30 days to decide whethe to approve the extradition, but Guzmán's lawyers say there are multiple appeals pending against extradition, and that to extradite him before these are exhausted would be a violation of his human rights. Mexico's Third District for Penal Processes, which approved the extradition, says that all legal requirements have been met. The identity of the judge in the case remains secret under special rules in place for prosecution of cartel bosses. (Jurist, BBC News)

Mayor Rosa Pérez Pérez of Chenalhó, Chiapas, stepped down May 26—after days of violence in the indigenous Maya municipality that even turned deadly. Pérez finally resigned after two state lawmakers from her Mexican Ecologist Green Party (PVEM) were taken captive by opponents at a meeting called to negotiate an end to the dispute at the offices of the Catholic diocese of San Cristóbal de las Casas. The lawmakers were forcibly removed from the premises by masked men who invaded the meeting and drove them to Chenalhó, where they were held to demand Pérez's resignation. By then, some 250 residents of outlying hamlets had fled inter-factional violence and taken refuge in government offices in Chenalhó's municipal center. A 56-year-old man was killed in fighting at the hamlet of Puebla. Violence has continued even after the resignation, with a 14-year-old girl shot in Puebla, where several homes were put to the torch. Opponents charged Pérez with diverting funds for development projects to her personal account, and say she represents the traditional ruling families of Chenalhó, who for the past generation have terrorized opposition with paramilitary groups to maintain power. The PVEM, now the ruling party in Chiapas, is assailed by critics as a "satellite party" of Mexico's ruling machine, the Institutional Revolutionary Party (PRI).

Striking teachers on May 28 took over the installations of three radio and TV stations in Tuxtla Gutiérrez, capital of Mexico's Chiapas state, in an ongoing campaign against President Enrique Peña Nieto's proposed education reform. Days earlier, state and federal police violently evicted a protest camp ste up by the teachers in Tuxtla's central plaza. The National Coordinator of Education Workers (CNTE) is demanding that the national government cancel the new education reform. Campesinos from rural Chiapas villages have mobilized local marches in support of the teachers. The pending reform would impose strict teacher evalutions, but critics say it fails to address the critical problem of under-resourced schools in poor areas of the country. The pending reform was crafted with the participation of business-friendly groups such as Mexicanos Primero, led by figures including Televisa president Emilio Azcárraga.

Presumed militants of the Niger Delta Avengers struck four pipelines in three days, halting production at key facilities. On May 25, militants blew up a pipeline at Chevron's Escravos facility in Delya state, shutting down all the company's onshore activities in the Niger Delta. The following day, militants hit a Nigerian National Petroleum Corporation (NNPC) pipeline at the Batan oil-field in Warri, Delta state. The day after that, pipelines operated by Shell and Agip in neighboring Bayelsa state were blown up. The NDA had days earlier warned Chevron that no repairs should be carried out on facilities previously targeted by the group, until their demands are fully met. NDA claimed on its official website May 11 that it suspected Chevron was preparing to carry out repair works at the Okan Valve platform, which was blown up by the group at the start of the month. Among its demands, NDA wants to "free the people of the Niger Delta from environmental pollution, slavery and oppression," according to a statement on the group's site. A May 31 deadline had been set for oil companies to quit the Niger Delta.

Argentina’s last dictator, Reynaldo Bignone, and other former military officers were sentenced to prison on May 27 for their roles in Operation Condor in the 1970s. The criminal court in Buenos Aires handed Bignone a 20-year prison term on top of his previous sentences for crimes against humanity. The trial began with 22 defendants, but five died or were absolved. According to attorneys for advocacy groups, this was an important step in human rights because "it is the first time the existence of Operation Condor has been proved in court." Operation Condor was a multi-state campaign that created and sanctioned death squads from South American countries to kidnap, torture and kill political opponents from each others' countries who had fled their country of origin. Evidence was produced during the trials that showed the US was aware of Operation Condor and played a role.

On May 25, Argentina's Revolution Day, some 20 townspeople in Jáchal, San Juan province, held a "patriotic march" to oppose the local operations of Barrick Gold—only to be surrounded and arrested by the police. Organizers said the march was peaceful, but the town's mayor, Miguel Vega, said that he was illegally detained and assaulted by protesters. The town saw a recent controversy, when the municipal council, with Vega's support, voted down a measure to hold a popular consulta or referndum on the mine's operations. (InfoBae, Diario La Provincia, May 26; Diario de Cuyo, May 19) Meanwhile, operators of Argentina's biggest open-pit mine at Bajo de la Alumbrera, Catamarca province, also the site of repeated protest campaigns, announced that the facility will be closing next year, its lode of gold and copper nearly exhasuted.

The US responded this week to the Syrian Kurds' declaration of autonomy, with State Department spokesman Mark Toner saying: "We've...made it clear to these Kurdish forces [in Syria] that they should not seek to create autonomous, semi-autonomous zones." He added that Kurdish forces in Syria "should not seek to retain the territory that they liberate, rather that they should make sure it's returned to whatever civilian authorities there are and able to—so that all displaced people can return there." This is a barely veiled reference to accusations that Syrian Kurdish forces are engaging in "ethnic cleansing" against Arabs and Turkmen in areas liberated from ISIS. But not only are these charges dubious, but Toner's statement ignores that often the only "civilian authorities" are in fact those of the Kurdish autonomous administration. More ominously, he warned that the US is in close dialogue with Turkey on the question and understands Ankara's "concerns regarding Kurdish forces in northern Syria." (This as Turkey is wagng a brutal counterinsurgency against Kurdish rebels within its own territory, to Washington's silence.) Ironically, he added that the Kurdish militias in Syria "are effective fighting forces and that they are willing to take on and dislodge Daesh," using the popular pejorative for ISIS in the Middle East.
