Following a first round of presidential elections May 29, "between two populisms" is the catchphrase being used by Colombia's media for an unprecedented moment. A pair of political "outsiders" are to face each other in the June 19 run-off: Gustavo Petro, a former guerilla leader and Colombia's first leftist presidential contender, versus Rodolfo Hernández, a construction magnate whose pugnacious swagger inevitably invites comparison to Donald Trump. Hernández, an independent candidate and the former mayor of Bucaramanga, rose precipitously in an ostensibly anti-establishment campaign driven by social media, winning him the epithet "King of TikTok." But Colombia's political establishment is now lining up behind him to defeat Petro. The former mayor of Bogotá and a veteran of the demobilized M-19 guerillas, Petro is the candidate of a new progressive coalition, Colombia Humana, emphasizing multiculturalism and ecology as well as more traditional social justice demands.

A report to the Security Council by a panel of UN human rights experts finds that foreign fighters and private military companies are responsible for grave abuses in Libya—especially naming Russia's Wagner Group. The report was classified "confidential," but a copy was leaked to the Associated Press. It finds that both Turkish-backed militias loyal to the Tripoli-based Government of National Accord (GNA) and the Wagner Group, apparently contracted by eastern warlord Khalifa Haftar, have employed mercenaries who were veterans of the internal war in Syria. The GNA-aligned militias are implicated in abuses of migrants, who have been "regularly subjected to acts of slavery, rape and torture." The Wager Group is accused of planting unmarked anti-personnel mines on the southern periphery of Tripoli, when the city was besieged by Haftar's forces from April 2019 to an October 2020 ceasefire.

Ukrainian prosecutor general Iryna Venediktova announced May 14 that her office is preparing war crimes cases against 41 suspects, on charges including "the bombing of civilian infrastructure, the killing of civilians, rape and looting." Venediktova has said that her office is investigating more than 10,700 potential war crimes involving more than 600 suspects.

A May 4 report from Amnesty International finds that a militia funded and backed by Libya's Tripoli-based Government of National Unity is responsible for a litany of crimes, including unlawful killings, torture, rape, forced labor, and the interception and return of migrants and refugees to the country's notoriously harsh detention centers. Created by government decree in January 2021, the Stability Support Authority (SSA) is commanded by one of the most powerful militia leaders in Tripoli, Abdel Ghani al-Kikli AKA "Gheniwa," who was appointed despite a well-documented history of crimes and serious human rights violations committed by forces under his command.

Forces in the Central African Republic, identified by witnesses as Russian mercenaries, "appear to have summarily executed, tortured, and beaten civilians since 2019," Human Rights Watch finds in a new report. On April 15, the United Nations announced it wil investigate the circumstances in which at least 10 people were killed in the CAR's northeast, with initial reports alleging involvement by Russian forces from the paramilitary Wagner Group. In the attacks three days earlier, up to 15 civilians were killed at the villages of Gordil and Ndah, some 1,000 kilometers northeast of the capital Bangui. Local officials and aid workers told AFP the attacks were carried out by elements of the "FACA [Central African Armed Forces] and their allies"—the term used by both the authorities and the UN for Russian mercenaries. HRW documents other such claims. On July 21, 2021, apparently Russian-speaking forces killed at least 12 unarmed men near the town of Bossangoa, some 300 kilometers north of the capital. HRW is calling upon the CAR's Special Criminal Court (SCC) or the International Criminal Court to "investigate these incidents as well as other credible allegations of abuse by Russia-linked forces with a view to criminal prosecution."

The junta in Mali is accusing France of spying and subversion after the French military used a drone to film footage that Paris says shows Russian mercenaries burying bodies in a mass grave near a military base. The French government says the bodies were buried outside the base at Gossi, Tombouctou region, in a scheme to falsely accuse its departing forces of leaving behind mass graves. Video from the drone was released after pixelated images appeared on social media of corpses being buried in sand, with text accusing France of atrocities in Mali. France claims the bodies were brought to Gossi from Hombori, immediately to the south, where Malian troops and Russian mercenaries have been carrying out an operation against jihadist insurgents. The junta has acknowledged that 18 militants were killed in the operation. (The Guardian, AfricaNews, BBC News, Al Jazeera)

A court created seven years ago to prosecute war crimes in the Central African Republic was due to open its first trial this month. But a no-show by defense lawyers means victims' associations and others pushing for justice will have to wait a little longer. The Bangui-based Special Criminal Court (SCC) is a hybrid tribunal composed of national and international jurists tasked with prosecuting war crimes, genocide, and crimes against humanity. It took time to become operational because of staff recruitment challenges, insecurity, and limited resources. Arrest warrants have also not been executed, and the government has released high-profile suspects without SCC authorization. Its inaugural trial—set to resume in April—concerns three members of the 3R rebel group accused of involvement in a 2019 massacre. Rebel groups remain active across the CAR, which has one of the highest per capita humanitarian caseloads in the world.

At least 150 were killed April 24 as paramilitary troops attacked a village in Sudan's conflicted Darfur region. Fighters from the Rapid Support Forces (RSF), many riding motorbikes or driving vehicles mounted with machine-guns, swept in on the village of Kereinik, torching houses and shops and firing on residents. More than 80,000 families fled their homes to seek refuge at the army headquarters in the village center. Hostilities between the Arab-dominated RSF and Masalit villagers began days earlier, after two Arab herders were reportedly killed by former rebel fighters. The fighting has since spread to the nearby town of  Geneina, capital of West Darfur state. Sudan's central government is said to be sending in military reinforcements and warplanes to contain the situation. (NYT, Dabanga, Sudan Tribune, NRC)
