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.

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.

Peru's President Ollanta Humala declared a 60-day state of emergency in the rainforest region of Madre de Dios in response to reports of mercury poisoning by outlaw gold-mining operations. According to country's Environment Ministry, as many as 50,000 people or 41% of the population of Madre de Dios, have been exposed to mercury contamination. The government plans to send hospital ships and loads of untainted fish to the area, where mercury has contaminated local waterways. Illegal gold production has increased five-fold in Peru since 2012, and it is estimated to provide 100,000 direct jobs in the country, 40% of which are in Madre de Dios. Peru is the world's sixth largest gold producer, but an estimated 20% of its annual output is of unknown origin. (Mining.com, La República, May 24)

Lima was treated to the spectacle of topless women being tear-gassed by police at a protest outside the Congress building against a new law to toughen strictures on abortion. Riot police broke up the semi-nude sit-in organized by feminist groups to oppose the pending legislation, which would impose penalties of 50 days community service on women who seek an abortion. Many of the women wrote "KEIKO NO VA" (Stop Keiko) on their torsos—a reference to right-wing presidential candidate Keiko Fujimori, who has recently taken a hard line on abortion, now opposing it even in cases of rape. Protesters also recalled her intransigent support for her father, imprisoned ex-dictator Alberto Fujimori, who carried out a campaign of forced sterilization of peasant women during his period in power in the 1990s.

A wave of student protests demanding education reform in Chile has been met with harsh repression, leading to charges of "torture" recalling the era of military rule. Clashes with police during President Michelle Bachelet's state-of-the-nation addres in Valparaiso made English-language headlines May 21. Demonstrators set up barricades and hurled fire-bombs, torching a pharmacy and supermarket, while police fired tear-gas and water cannon. A security guard reportedly died from smoke inhalation. Three days later, protesters actually invaded the presidential palace in Santiago, forcing their way past guards. Winning few headlines outside Chile is the controversy over abuse of arrested protesters. Most egregious is the case of Roberto Zambrano Freire, 18, who was arrested at a protest outside the National Institute, the country's most prestigious school, on May 17 and apparently beaten after being made to strip naked while in custody. The student's father, Roberto Zambrano Sepúlveda, says he is pressing for an investigation but is not optimistic, noting that "It is my boy's word against the Carabineros." He added: "The Carabineros of Chile continue operating with the same methods as the under the dictatorship." (TeleSur, BBC News, Diario UChile, BiobioChile, La Tendencia, RPP, Univision)

A court on the Greek island of Lesbos on May 20 ruled that Turkey is an "unsafe third country" for asylum seekers, throwing into doubt the EU-Turkey migrant deal. The panel of judges refused to reject an asylum application by a Syrian refugee and have him deported to Turkey. The decision came the same day that 51 refugees and migrants of different nationalities were forcibly returned to Turkey by Greek authorities. (Ekathimerini, May 20) Amnesty International's Giorgos Kosmopoulos hailed the decision, charging that Turkey is not complying with standards of the Refugee Convention. "Until it becomes a safe country nobody should be returned there," he said. He cited violations of the rights to work, medical care and family life, and said there have been "widespread returns of Syrians back to Syria from Turkey." On the pact with the EU, he added: "The whole deal should stop and refugees should be settled in other European countries safely and with dignity." (BBC News, May 21)

Security forces opened fire on protesters storming Baghdad's Green Zone on May 20, killing three and wounding some 20. A journalist covering the protest was also killed. Thousands of demonstrators had gathered in the capital's Tahrir Square before several hundred tried to enter the fortified Green Zone, which houses government institutions and foreign consulates. Security forces responded to the breach by opening fire on the protesters, using tear-gas and live rounds. Protesters had reportedly entered the prime minister's office before they were forced to retreat. The incident marked the second time in recent weeks that protesters mobilized by Shi'ite cleric Moqtada al-Sadr succeeded in breaching the Green Zone, demanding reform and an end to corruption. After this new breach, Sadr issued a statement to his followers, saying: "I respect your choice and your peaceful spontaneous revolt. Curse the government that kills its children in cold blood." (Rudaw, Rudaw, Rudaw, May 20)
