On Oct. 22 three Costa Rican environmental activists marked two weeks on hunger strike against the projected Las Crucitas open-pit gold mine in San Carlos in the north of the country. Some 14 activists from two organizations, the North Front Against Mining and the Not One Mine Coordinating Committee, began the action on Oct. 8 in an encampment in front of the Presidential Residence in San José. Most of the 14 ended their fast for medical reasons but continued to support the three remaining strikers.

Thousands of Argentines rallied in the Plaza de Mayo in Buenos Aires on Oct. 21 to protest the killing of the student Mariano Ferreyra during a demonstration the day before. Ferreyra, a member of the Trotskyist Workers Party (PO), was shot in the chest in what appeared to be a clash between armed members of the Railroad Workers Union (UF) and temporary workers demanding that laid-off workers get permanent employment with the Roca Railroad, which was privatized in the 1990s. Three others were wounded in the incident, one seriously. There were reports that the police did nothing to stop the supposed UF members when they attacked the protesters.

Two unidentified men shot and killed Catarino Torres Pereda, general secretary of the Citizen Defense Committee (Codeci), at the indigenous rights group's office in Tuxtepec in the southern Mexican state of Oaxaca on the afternoon of Oct. 22. The murderers escaped in a car waiting for them nearby. In the evening members of Codeci and other organizations protested the assassination with a demonstration at the Alameda de León plaza in the city of Oaxaca, the state capital.

Bolivian President Evo Morales, on an official visit to Iran, said Oct. 25 that the Islamic Republic and Bolivia pursue a common objective in fighting against imperialism and injustice in the world. "Iran and Bolivia have identical revolutionary conscience which allows for the expansion of relations and accounts for the closeness of the two states," IRNA reported the Bolivian leader as saying in the northwestern Iranian city of Tabriz.

UN Special Rapporteur on torture Manfred Nowak called Oct. 23 for the Obama administration to launch an inquiry into the role of the US in human rights violations allegedly committed in Iraq. Nowak's comments follow the release of government information on WikiLeaks that included thousands of previously classified documents. Many of the documents purportedly illustrate instances of abuse, torture and murder carried out by US and Iraqi forces.

Canadian Guantánamo Bay detainee Omar Khadr on Oct. 25 pleaded guilty to all five charges against him, including conspiracy, murder and aiding the enemy. Under the terms of the agreement, Khadr will serve up to eight more years in prison in addition to the eight he has already spent in detention. At least one of those years will be spent at Guantánamo Bay. One other purported condition of the plea is that the US will support Khadr's eventual application for transfer to Canada, a bargain that has been agreed to by the US and Canada through a series of sealed diplomatic notes. The guilty plea marks a reversal from Khadr's original stance, voiced by one of his attorneys, that he would not accept a plea deal. Khadr's sentence will be determined by a panel of seven senior military officers at a hearing that will begin this week.

On Oct. 22, Costa Rica dispatched a group of some 70 heavily armed national police to the northern border following claims of an incursion by Nicaraguan soldiers, who were reported to be causing damage to local properties. The police troops apparently found no evidence of an incursion, but Costa Rican Public Security Minister José María Tejerino said a contingent will be permanently stationed at Barra del Colorado border outpost as a preventative measure.

At least 13 young people were shot dead and 15 wounded in an attack on a house party in Ciudad Juárez—the second such massacre in less than a week in the violence-torn Mexican city bordering Texas. Gunmen in three cars drove up to the home around 11 PM on Oct. 22 and began shooting, the Chihuahua state prosecutor's office said. The dead were 14 to 20 years old, and a 9-year-old was gravely wounded. On Oct. 17, gunmen similarly stormed two homes in Ciudad Juárez, killing nine young people. (AP, Oct. 23)
