Tens of thousands of students, teachers and supporters protested Chile's education policies with a huge demonstration in Santiago on June 16 that the local daily La Tercera said was "the most massive march since the return of democracy" in 1990; the University of Chile radio station called it "historic." The Carabineros militarized police gave a crowd estimate of 80,000, while organizers said 100,000 people had attended. Thousands more held marches in the cities of Concepción, La Serena, Temuco and Valparaíso. The nationwide protest followed several days of student strikes at dozens of high schools and universities.

More than 5,000 agricultural workers blocked the Trans-Amazonian highway in the northern Brazilian state of Pará on June 15 and 16 to push demands for land, government aid and an end to violence against activists. They continued the action after one protester was run over and killed on June 15, but they agreed to open up the highway on June 16 as the result of an agreement for Presidency Minister Gilberto Carvalho and representatives of the Mining and Energy Ministry and the Agrarian Development Ministry to meet with them on June 20.

A group of Haitians left homeless by a January 2010 earthquake demonstrated in Port-au-Prince on June 10 to demand action on the housing situation and an end to forced evictions from the displaced persons camps. "We've had enough of living in tents, we want decent housing" was one of the slogans. The protest followed violent evictions from camps in the Delmas section of Port-au-Prince carried out on May 23 and May 25 by Delmas municipal authorities and agents of the National Police of Haiti (PNH).

Leaked US diplomatic cables show that "[t]he US embassy in Haiti worked closely with factory owners contracted by Levi's, Hanes, and Fruit of the Loom to aggressively block a paltry minimum wage increase for Haitian assembly zone workers" in 2009, according to an article in the New York and Haiti-based weekly newspaper Haïti Liberté. The article, published jointly with the US weekly magazine The Nation, is based on some of the 1,918 previously unpublished cables concerning Haiti that the WikiLeaks group has released to Haïti Liberté.

Statistics given to US senator Dianne Feinstein (D-CA) by the US Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) confirm claims that a high percentage of the illegal firearms in Mexico are smuggled from the US, although less than the 90% sometimes claimed in the past. The availability of illegal weapons in Mexico is a major factor in the more than 35,000 drug-related deaths in the country since President Felipe Calderón Hinojosa began militarizing the fight against drug cartels in December 2006.

Campesino organizations from the Lower Aguán Valley in northern Honduras marched in Tegucigalpa on June 9 to protest the killings of Aguán campesinos and to demand that the government act on its promise last year to distribute 3,000 hectares of land to campesino families. The Honduras section of the international campesino group Vía Campesina joined in the demonstration, along with the Alliance for Food Sovereignty and Agrarian Reform (SARA) and members of the National Popular Resistance Front (FNRP), the country's main alliance of social movements. The groups say 39 campesinos have been murdered in the course of a longstanding land dispute in the valley.

On June 9 four Mapuche activists imprisoned in Chile's central Araucanía region decided to end a liquids-only hunger strike they started on March 15 to protest their convictions in what they considered an unfair trial. The prisoners—José Huenuche Reimán, Jonathan Huillical Méndez, Héctor Llaitul Carillanca and Ramón Llanquileo Pilquimán—stopped the fast after relatives, human rights organizations and members of the Catholic church made an agreement to form a Commission for the Defense of the Rights of the Mapuche People to promote and defend indigenous rights.

The WikiLeaks group is releasing a total of 1,918 previously unpublished US diplomatic cables concerning Haiti to the weekly newspaper Haïti Liberté, which is published in New York and Port-au-Prince. The cables cover a period of seven years, from April 17, 2003 to Feb. 28, 2010, shortly after the January 2010 earthquake that shattered much of southern Haiti. The newspaper is planning a series of articles based on the cables. The first article, which appeared in the May 25-30 edition, details US diplomats' unsuccessful efforts to keep former president René Préval (2006-2011) from having Haiti join PetroCaribe, a program through which Venezuela supplies oil to Caribbean Basin countries on favorable terms. Later articles are to show how the US government backed assembly plant owners fighting an increase in the minimum wage and how the US militarized the distribution of aid after the earthquake.
