On May 10, Mexico's Day of the Mother, thousands of mothers and other family members of the disappeared held a March for National Dignity in the capital, calling for action on their missing loved ones. The march, which filled the main avenues of Mexico City, was organized by a coalition made up of 60 regional collectives of survivors of the disappeared from around the country. In the days before the march, a group camped out outside the National Palace, demanding a dialogue on the matter with President Andrés Manuel López Obrador.

The International Court of Justice (ICJ) at The Hague on April 21 ruled that Colombia must end its "interference" in parts of the Caribbean off the coast of Nicaragua, and bring under control fishing and other activities in the zone. This culminates a long conflict between Nicaragua and Colombia. In two rulings in 2007 and 2012, the ICJ recognized the sovereignty of Colombia in the islands constituting the Archipelago of San Andrés. However, the rulings also recognized the jurisdiction of Nicaragua in the surrounding waters. Colombia continued its activities in those waters, prompting Nicaragua to file a new complaint with the Court in 2013. Colombia argued that its actions were necessary to fight drug trafficking and secure environmental protection of the waters. In its new ruling, the ICJ found that these waters are within the exclusive economic zone of Nicaragua, and the "intervention" of another state is contrary to international law.

El Salvador's Legislative Assembly approved a state of emergency March 27 at the request of President Nayib Bukele, in response to a sharp increase in the number of killings by criminal gangs. The emergency regimen seeks to dismantle criminal structures by prohibiting associations and disrupting their communications. It also extends the "administrative detention" period, and suspends certain constitutional freedoms.

Gunfire and explosions were reported from the Mexican border town of Nuevo Laredo in the early hours of March 14, following the arrest of a local gang leader by federal police and army troops. Juan Gerardo Treviño, also known as "N" or "El Huevo" (The Egg), is said be leader of the Tropas del Infierno (Troops of Hell), paramilitary arm of the Cartel del Noreste (Northeast Cartel), an offshoot of the notorious Zetas. Facing charges both sides of the border, he was nonetheless turned over to US authorities, apparently because he is a US citizen. He was handed over at a border bridge in Tijuana, far to the west of Nuevo Laredo, presumably to avoid attempts to free him. In the outburst of violence that greeted his arrest in Nuevo Laredo, the city's US consulate was hit with gunfire. Gang members also closed off streets with burning vehicles, attacked army outposts, and lobbed grenades at buildings. (Laredo Morning Times, Border Report, AP, La Jornada)

Mexico's President Andrés Manuel López Obrador on Feb. 9 called for a "pause" in relations with Spain, in a speech that explicitly invoked the legacy of colonialism going back to the Conquest. But the speech was clearly aimed principally at Spanish oil company Repsol, which had been favored during the presidential term of Felipe Calderón. Specifically, López Obrador questioned the granting of gas contracts in the Burgos Basin, in Mexico's northeast. He charged that Repsol operated the fields less productively than the state company Pemex had. "In the end, less gas was extracted than Pemex extracted" before the contracts, he charged.

The US Supreme Court this month heard oral arguments for two immigration cases that address the right of detained non-citizens to have a bond hearing after six months of detention. Both cases were brought by asylum-seekers who had been detained for extended periods without bond hearings following the issuance of a removal order.

A year-end report by Mexico's government registered a figure of 95,000 missing persons nationwide, with an estimated 52,000 unidentified bodies buried in mass graves. The report by the Comisión Nacional de Búsqueda de Personas (National Missing Persons Search Commission) found that the great majority of the disappearances have taken place since 2007, when Mexico began a military crackdown on the drug cartels. Alejandro Encinas, the assistant interior secretary for human rights, said that there are 9,400 unidentified bodies in cold-storage rooms in the country, and pledged to form a National Center for Human Identification tasked with forensic work on these remains. He admitted to a "forensic crisis that has lead to a situation where we don't have the ability to guarantee the identification of people and return [of remains] to their families."

Rural communities in Colombia's northeastern Arauca department held anti-war protests amid inter-factional guerilla violence that has been terrorizing the region. Demanding attention from the government and international human rights organizations, some 1,200 marched in the hamlet of Puerto Jordan on Jan. 4, and another 500 in nearby Botalón, both in Tame municipality. Mayerly Briceño, an organizer of the protests in Tame, told El Espectador: "The state has no presence here, absolutely none; they only come here to protect the oil companies, to safeguard the petroleum. This is not about them coming to militarize... More zones are leaving behind fear and taking to the streets to demand peace. It is the only thing we can do as a people, to demand that peace comes to our territory."
