On Nov. 20 tens of thousands of protesters marched through downtown Mexico City in the fourth National and Global Day of Action for Ayotzinapa, demanding the return of 43 missing students from the Raúl Isidro Burgos Rural Teachers' College, located in Ayotzinapa in the southwestern state of Guerrero. The students were abducted the night of Sept. 26-27 in the Guerrero city of Iguala de la Independencia, apparently in a joint action by municipal police and local drug gangs; three other students were killed in the incident, along with three bystanders. The Nov. 20 demonstration, which also marked the official anniversary of the start of the 1910 Mexican Revolution, coincided with the arrival in the capital of three caravans led by parents of the missing students; the parents had spent a week traveling through different parts of Mexico to increase public awareness about the disappearances.

Two students were wounded on Nov. 15 at the campus of the National Autonomous University of Mexico (UNAM), in the Coyoacán section of the Federal District (DF, Mexico City), when a police agent fired his pistol at a group of youths. Witnesses said the incident started when two men from the DF judicial police and two women from the DF prosecutor's office arrived in a car and began photographing students near the Che Guevara Auditorium; student activists have been meeting in the auditorium to plan actions protesting the killing of six people and the abduction of 43 teachers' college students in Iguala de la Independencia in the southwestern state of Guerrero the night of Sept. 26-27. When a group of students challenged the four officials, one of the two agents responded by assaulting a student and then firing his pistol at the ground. The same agent fired again, several times, as all four officials fled the campus on foot, pursued by a group of students. The shots wounded one student in the foot and grazed another student's knee; a dog was also injured.

A group of 43 Mexican teachers' college students missing since the night of Sept. 26-27 were killed by gang members and their bodies were burned and disposed of in Cocula municipality in the southwestern state of Guerrero, federal attorney general Jesús Murillo Karam announced at a Nov. 7 press conference in Mexico City. Three members of the Guerreros Unidos ("United Warriors") criminal organization confessed to having participated in the execution of the students and the incineration of their bodies, according to Murillo Karam, who said the remains were so thoroughly burned that it might be difficult to extract DNA for identification. The Mexican government is planning to send the remains to technicians in Austria. The attorney general said he understood the skepticism of the students' parents about his office's findings, more than a month after the events: "It's natural…and it doesn't surprise me."

Students, teachers and parents attacked government office buildings in Chilpancingo, the capital of the southwestern state of Guerrero, on Oct. 13 in ongoing protests over the killing of six people, including three students, and the disappearance of 43 other students in Iguala de la Independencia the night of Sept. 26-27. The demonstrators blocked the entrances to the main state office building from around 11 am, keeping some 1,500 employees trapped for more than five hours. In the evening, after some skirmishes with riot police, the protesters broke into one of the buildings and set it on fire. There were also attacks on various vehicles and on Chilpancingo's city hall.

Tens of thousands of people demonstrated in Mexico and internationally on Oct. 8 to protest the killing of six people and the wounding of at least 20 more the night of Sept. 26-27 by municipal police and people in civilian dress in the city of Iguala in the southwestern state of Guerrero. The demonstrators demanded the return of 43 students who have been missing since that night; all are from the militant Raúl Isidro Burgos Rural Teachers’ College in the town of Ayotzinapa. "They were taken alive, we want them back alive" and "We are all Ayotzinapa" were among the slogans protesters chanted in at least 25 Mexican states and 60 cities, including many in other countries, along with calls for the Guerrero state government and Mexico’s federal government to "go away.”

On Oct. 4 authorities in the southwestern state of Guerrero announced that they had found charred human remains in a group of mass graves in Iguala de La Independencia municipality, at Pueblo Viejo community in the countryside northwest of the city. Guerrero chief prosecutor Iñaky Blanco Cabrera would only say that there were human bones and that specialists would need to use DNA tests to identify the victims. State police agents at the site on Oct. 4 told reporters off the record that there could be anywhere from four to 19 bodies, but on Oct. 5 Blanco Cabrera said the total number was 28. It seemed likely that the remains were of teachers' college students missing since the night of Sept. 26-27, when Iguala police opened fire on three buses carrying students from the militant Raúl Isidro Burgos Rural Teachers' College, located in the town of Ayotzinapa. Originally 25 students were reported missing after the incident, but parents and student leaders later raised the number to 43.

An Israeli military offensive on the Palestinian territory of Gaza starting on July 8 has brought widespread condemnation from governments and activists in Latin America. The response to the current military action, which is codenamed "Operation Protective Edge," follows a pattern set during a similar December 2008-January 2009 Israeli offensive in Gaza, "Operation Cast Lead," when leftist groups and people of Arab descent mounted protests and leftist and center-left governments issued statements sharply criticizing the Israeli government.

Latin American activists joined thousands of environmentalists and farmers around the world in an international protest May 24 against genetically modified (GM) crops and Monsanto, the Missouri-based multinational that dominates the transgenic seed industry. This was the third March Against Monsanto since May 25 last year, and organizers expected the day of action to include protests in some 351 cities in 52 countries.
