Campesinos launched a strike across Colombia May 31, with some 100,000 blocking highways and effectively shutting down at least half of the country's 32 departments. One is reported dead from clashes at a roadblock outside the main Pacific port of Buenaventura, and four soliders were briefly detained by protesters on the Quibdó-Medellín highway. The "indefinite" strike, or National Agrarian Minga, was called to protest the economic policies of President Juan Manuel Santos, and especially to press him on promises made in 2013 to end a similar national strike that left dozens dead. "They have not complied with 30% of the accords," said Robert Daza of the Agrarian Summit. He charged Santos with drawing up a National Development Plan that corresponds to the needs of the Free Trade Agreement with Washington rather than Colombia's small producers. Daza said Santos is "putting the strategic resources of the nation up for sale [and] distributing the land in an unequal manner."

A court in Senegal convicted former Chadian dictator Hissène Habré of crimes against humanity committed during his rule from 1982 to 1990, and sentenced him to life imprisonment on May 30. He was found guilty of sex slavery, rape and the ordered killings of an estimated 40,000 people. The trial marks the first time a court with backing from the African Union has tried a former ruler for human rights violations, and also the first time a former African head of state was found guilty by an another African country. Habré has 15 days to appeal the sentence. Human Rights Watch lawyer Reed Brody, who initiated the trial, stated: "This verdict sends a powerful message that the days when tyrants could brutalize their people, pillage their treasury and escape abroad to a life of luxury are coming to an end. Today will be carved into history as the day that a band of unrelenting survivors brought their dictator to justice."

The 2009 coup d'etat in Honduras has recently been in the news due to revelations that it was lubricated by then-Secretary of State and current Democratic presidential frontrunner Hillary Clinton. Now comes the embarassing news that the son of Honduras' ex-president Porfirio Lobo has pleaded guilty to cocaine trafficking charges in a federal court in Manhattan, and faces a mandatory 10-year prison term. Fabio Lobo, 44, admitted to scheming to import a “multi-ton load” of cocaine into the US. Federal prosecutors said the younger Lobo was snared by DEA informants who went undercover as traffickers and started collecting evidence against him in 2013. They popped him in Haiti a year ago, and put him on a plane to New York. Said US Attorney Preet Bharara: "Whether you are a street-level dealer, a member of a cartel, or the son of a former foreign president, drug dealing is drug dealing. It is a serious federal crime for which you will be prosecuted."

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.
