Colombia's oldest rebel group FARC has undergone significant changes concerning military strategy since entering the ongoing peace talks with the government, according to a new report. The report by think tank Fundación Paz y Reconciliación which was partly released in national newspaper El Espectador on Dec. 17 revealed how the rebel organization changed their military strategies, adapting to the rhythm of this year's peace talks. "In September and October when the negotiations were in a crisis due to a lack of progress concerning the point of political participation, [the FARC] launched a minor offensive, attacking the oil and energy infrastructure that left Tumaco 20 days without power. This shows that the operational capacity of the FARC is not that decimated," the report was quoted in El Espectador.

The Fiscalía, Colombia's public prosecutor, on Dec. 9 formally charged a notorious drug kingpin for masterminding several massacres between 1988 and 1994 in which hundreds of people were killed. The crimes, dubbed the Massacre of Trujillo after the town where they were committed in Valle del Cauca department, resulted in the deaths of up to 342 people. Among the victims were unionists, alleged guerrilla supporters, and a priest. Some of the victims were tortured and dismembered as a warning to rebel groups FARC and ELN, and their sympathizers. Diego Montoya AKA "Don Diego" is accused of conspiring with members of the army, police, regional politicians and paramilitary groups aligned to the infamous Cali Cartel. Several members of the security forces have also been charged for their alleged role in the killings.

For a second consecutive day Dec. 10, thousands of protesters continued to occupy Plaza Bolívar, the central square in Bogotá, to oppose the removal of the Colombian capital's populist mayor, Gustavo Petro. A left-wing populist and former guerilla fighter, Petro was ordered to step down by Colombia's Prosecutor General Alejandro Ordoñez—officially over irregularities in a reform of the city’s garbage collection system. Under the decision, Petro is barred from holding public office for 15 years. But Petro told his supporters in the plaza, "I am still mayor," and assailed Ordoñez's decision as a "coup against democracy." Protesters pledge to remain in the plaza until the decision is overturned, with banners reading "Respect my vote," and accusing the conservative Ordoñez of being a "golpista" (coup-plotter.)

Some 100 troops from ESMAD, the feared Mobile Anti-Disturbance Squadron of the Colombian National Police force, were mobilized Nov. 21 to the corregimiento (unincorporated village) of Urimaco, in the outlying rural zone of Cúcuta, capital of Norte de Santander department, to evict an encampment of campesinos who had been displaced from their homes by political violence in the region. At least 50 makeshift dwellings and small farm plots were destroyed in the operation, carried out at the behest of Cúcuta municipal authorities. Local attorney Germán Urbina says he intends to bring suit against the authorities, charging the eviction was carried out in violation of an April order from Colombia's Constitutional Court mandating that new housing be provided for the squatters before they could be expelled.

Two gunmen described as sicarios (hired assassins) killed Juan Álvaro Pai, a traditional governor of the Awá indigenous people, in an incursion into the resguardo (reserve) Inda Guacaray, in Colombia's southern Nariño department, Nov. 30. The gunmen arrived in the resguardo on a motorcycle, immediately made for Pai's home, and upon finding him fired six bullets into his body. Víctor Gallo, mayor of local Tumaco municipality, demanded that the Fiscalía (public prosecutor) and National Police open an urgent investigation, protesting the atmosphere of "impunity" that allows aggression against the Awá. In early July, Awá held a public demonstration, blocking the Pan-American Highway for a week, to protest the violence directed against their communities by various armed actors in Colombia's civil war. 

Sergio Úlcue Perdomo, a campesino leader representing veredas (hamlets) in the municipality of Caloto, in Colombia's southwestern Cauca department, was killed by unknown gunmen in civilian clothes who invaded his family's shelter in vereda Marañón on Nov. 17. Family members, including children, looked on as he was slain. The family has been living in the improvised shelter since November 2011, when they were forced by paramilitary threats to abandon their traditional lands and home in vereda El Pedregal. In 2009, Úlcue Perdomo led an effort to document rights abuses by the Colombian army and allied paramilitaries at the veredas of El Pedregal and El Vergel, bringing a complaint before the Inter-American Commission on Human Rights (CIDH) on behalf of some 175 families. The CIDH issued a "Precuationary Measure," MC-97-10, calling on the Colombian government to guarantee the safety of the threatened families. (Corporación Justicia y Dignidad via Rebelión, Nov. 19)

Colombia's government and the FARC rebels signed a landmark agreement on Nov. 6 that is supposed to guarantee the guerrilla group's political participation. The accord is the second of six foreseen pacts to end nearly 50 years of civil war in Colombia. "We have come to a fundamental agreement about the second point of the agenda," FARC and government negotiators said in a joint statement read by the Norwegian delegate, one of the mediators at the peace talks in Havana. The pact, which comes just two weeks before the one-year anniversary of the opening of the talks, outlines "guarantees for the exercise of the political opposition in general and in particular for the new movements that arise after the signing of the Final Agreement." Details are not be made public until a final deal has been signed.

The Constitutional Court of Colombia ruled in an unreleased decision on Oct. 23 that a constitutional amendment and pursuant statute (PDF) expanding the military justice system is unconstitutional. Magistrate Jorge Ivan Palacio announced that the decision was based on "procedural defects" within the law. The measure would have placed violations of international human rights law involving the armed forces—categorizing them as acts related to military service—under the jurisdiction of an expanded military justice system. Advocacy groups such as Human Rights Watch have alleged that the measure would have increased impunity for human rights violators. Defense Minister Juan Carlos Pinzón, however, expressed the belief that the ruling was a blow to the military that would decrease morale. He also suggested that the government would attempt a revised version of the bill. Under the current law, all human rights cases are to be tried in civil court. The decision is not subject to appeal.
