Hundreds of taxi drivers from across Colombia converged on Bogotá March 14, clogging the streets and blocking intersections to demand the government ban Uber. Streams of slow-moving yellow cabs, many sporting with the Colombian tri-color flag finally joined in a caravan that ended in a mass rally at the Plaza de Bolívar. A handful of taxi drivers were arrested for forcing passengers out of cabs and other infractions, and a dozen vehicles impounded. At least one Uber driver's vehicle was reportedly damaged.  The mobilization, dubbed "M-14," was joined by labor unions, students, miners, truckers and campesinos both in the capital and in solidarity protests around the country. Opposition to President Juan Manuel Santos' austerity program was also a part of the mobilization's demands.

Venezuela's President Nicolás Maduro on March 9 ordered creation of a "Special Military Zone" in the so-called Orinoco Mineral Arc following reports of a massacre of at least 28 at a mining camp in the region. The order came after survivors and kin of the disappeared miners blocked roads connecting the remote region with the city of Tumeremo to demand action. Witnesses said the camp, in Sifontes municipality, was seized by armed men who gunned down the workers, dismembered their bodies with a buzz-saw, then forced survivors to load the remains in a truck which drove off into the jungle. "We won't rest until we find those responsible for these acts, which in the eyes of all Venezuelans are abominable," said Defense Minister Vladimir Padrino. But Bolívar state Gov. Francisco Rangel of the ruling PSUV was assailed by miners and the opposition for denying that any massacre had taken place. "So far there's not any indication of any person killed or missing," he said March 7, three days after the reports first broke. "What happened there, according to the security forces, was another clash between armed gangs that are trying to control mining activities in the area."

Despite the peace process in Colombia, assassinations continue against leaders of the country's campesino and indigenous communities who stand up to landed interests. On Feb. 28, Maricela Tombé, a leader of Playa Rica community, in El Tambo municipality of Cauca department, was killed by unknown gunmen in the village center. The mother of two children, Tombé was the former president of the Environmental Campesino Association of Playa Rica, and had led efforts at community land recovery. Leaflets threatening the community and signed by a local paramilitary group had recently been left in El Tambo. (El Tiempo, March 1) Late January saw the disappearance of Henry Pérez, a community leader at La Gabarra, Tibú, Norte de Santander, after menacing leaflets had similarly been left in local villages.

The city council of Ibagué, capital of Colombia's Tolima department, voted Feb. 29 to a approve a popular "consulta" on a proposed mineral project for the municipality—two months after Mayor Guillermo Alfonso Jaramillo proposed the ground-breaking move. AngloGold Ashanti hopes to develop an open-pit gold mine at La Colosa in neighboring Cajamarca municipality, which could impact the Río Coello that flows into Ibagué and provides much of its water supply. Another downstream municipality that depends on the river, Piedras, declared against the project following a similar popular consultation in 2013. But the upcoming Ibagué vote marks the first time a departmental capital will hold such a process on a development project. Jaramillo cites Law 136 of 1994, which gives municipalities the right to determine the development of subsoil resources within their territories.

Agents of Colombia's Fiscalía General on Feb. 26 arrested Santiago Uribe Vélez, brother of former president and current right-wing senator Álvaro Uribe Vélez for alleged involvement in the 12 Apostles paramilitary group that terrorized Yarumal municipality, Antioquia department, in the 1990s. The prominent Yarumal rancher was arrested in Medellín, and is said to be suspected of aggravated homicide "delinquency"—meaning involvement in organized crime. An investigation opened in 2014 into his role in the paramilitary group, which is said to have carried out a campaign of at least 33 assassinations of suspected FARC supporters. (El Espectador, El Espectador, Feb. 29) Attorney Daniel Prado Albarracín, representing victims of the 12 Apsotles, is calling for the Santiago Uribe to also be investigated on charges of torture and forced displacement. (El Espectador, March 1)

Amid controversial proposals for a "demobilization zone" where FARC fighters could gather before laying down arms under a pending peace accord, leaders of Colombia's indigenous peoples have volunteered to have their autonomous authorities oversee the process. Legislative deputy Germán Bernardo Carlosama López, representing the indigenous district of Gran Mallama, Nariño department, last week sent a letter to Interior Minister Juan Fernando Cristo posing indigenous authorities as a neutral force that could secure the demobilization zones. He stated: "The FARC have made clear that it is not prudent that members of the Public Force be resposible for guaranteeing the security of these possible zones; therefore, the experience and wisdom that characterizes the Indigenous Guard, with its example of dignified defense of human rights and model of peaceful resistance, could open and pave the way for this momentous process." A contingent of indigenous leaders has traveled to Havana, Cuba, to discuss the idea with negotiators. (El Espectador, Feb. 25)

Protesters opposed to the Trans-Pacific Parternship marched through downtown Lima Feb. 25 and engaged in clashes with police, as a break-away group vandalized the headquarters of the APRA party. Lima has seen at least four protests against the TPP since Peru signed the agreement in New Zealand on Feb. 4, but these were the first to end in violence. Police used tear-gas after protesters threw rocks and set fires. "The TPP is the most dangerous trade agreement signed in history because it threatens national sovereignty, access to medicine and the Internet, healthy eating and a clean environment," read flyers passed out by the protesters. Protest organizers Dignity Collective denied having vandalized the APRA building in a statement the following morning, while also condemning "excessive repression" by the police and demanding that the 20 arrested protesters be freed. Former Cabinet chief Jorge del Castillo responded in comments to the media that the protesters were sympathizers of the Shining Path. (Peru Reports, Feb. 26; Prensa Latina, Feb. 25)

Exit polls suggest Bolivia's President Evo Morales has narrowly lost a referendum to amend the constitution and allow him to run for a fourth consecutive term. The constitution change would let Morales remain in power until 2025. Opposition supporters are already celebrating the referendum result in parts of La Paz.  However, Vice President Alvaro García Linera said the results so far are a "technical tie." The vote takes place amid controversy over who is responsible for a deadly incident of political violence four days earlier in El Alto, the sprawling working-class suburb of La Paz that is a traditional stronghold of Morales' ruling Movement Toward Socialism (MAS).
