The tri-border region where the Sahel countries of Burkina Faso, Niger and Mali come together is the scene of fast-mounting massacres by presumed Islamist militants. At least 80 people were killed in an ambush in Burkina Faso on Aug. 18. The target was a  convoy near the town of Arbinda, but scores of civilians were slain along with 17 soldiers and members of a pro-government militia. On Aug. 4, presumed militants killed 30 civilians, soldiers and militiamen in an attack near the town of Markoye. The assailants first attacked civilian villagers, and then fired on soldiers responding to the raid. State media reported that government troops killed 16 of the attackers.

At least three people are dead following an outbreak of inter-communal violence in Djibouti on Aug. 1. Fighting erupted in several areas between members of the Afar ethnic group, which straddles Djibouti's borders with Ethiopia and Eritrea, and the Issa, the country's other main ethnicity, which is a sub-group of the Somali people and straddles the borders with Ethiopia and Somalia. Issa protesters blocked the rail line and road connecting Djibouti's port to Ethiopia, a key artery for the landlocked Horn of Africa giant. The violence came in response to a deadly attack on Somali Issa civilians four days earlier within Ethiopia. Militia fighters from Ethiopia's Afar region raided the town of Gedamaytu (also known as Gabraiisa) in neighboring Somali region, reportedly killing hundreds of residents. The two regions have long been at odds over three contested kebeles (districts) on their shared border, which are predominately inhabited by Issa but located within the regional boundaries of Afar.

Mozambique's President Filipe Nyusi is usually wary of foreign military intervention. But the grim situation in Cabo Delgado seems to have forced his hand. Last week, Rwanda began deploying a 1,000-strong police and military force to the insurgency-hit northern province. And troops from the Southern African Development Community regional bloc are also set to arrive in the coming days. Some reports suggest the Rwandans will set up around the Afungi peninsula, where a multi-billion dollar gas project is located. Their battlefield enemy—known locally as al-Shabab—is formidable and entrenched, as Mozambique's army and its mercenary allies know well. Lost in the military chatter is much mention of Cabo Delgado's worsening humanitarian crisis: More than 700,000 people have been uprooted—68,000 since late March—and close to a million are now facing severe hunger.

The war in Ethiopia's Tigray region appears to have entered a dangerous new phase, as Addis Ababa reneged on a unilateral ceasefire July 14. Ethnic militias are now mobilizing from across Ethiopia. Prime Minister Abiy Ahmed started to pulled federal troops out of the northern region last month amid a string of battlefield losses to the rebel Tigray Defense Forces (TDF). But he reversed course as the TDF launched a fresh offensive to recapture western lands annexed by neighboring Amhara region during the eight-month conflict. Amhara officials assert that the lands belong to their region, and are calling up a militia force, risking a widening ethnic conflict. Also entering the fray are forces from Oromia (Abiy's home region), Sidama, and the Southern Nations, Nationalities & Peoples (SNNP) region. Escalation now seems inevitable in a war that has already left hundreds of thousands facing famine.

Pre-Trial Chamber II of the International Criminal Court (ICC) issued a decision on July 9, unanimously confirming charges against Sudanese militia leader Ali Muhammad Ali Abd-Al-Rahman. Consequently, Abd-Al-Rahman, who is also known as Ali Kushayb, was committed to trial before an ICC trial chamber. Abd-Al-Rahman was a top commander of the Janjaweed militia, and one of the most senior leaders in the tribal hierarchy in Wadi Salih locality, Central Darfur state. He is also a leader of the Popular Defense Forces, the more regularized successor to the Janjaweed. He is alleged to have led pro-government campaigns against Darfur rebel groups, ultimately displacing 40,000 and murdering 300 civilians.

An apparent squad of mercenaries, arriving in nine brand-new Nissan Patrol vehicles, staged a night raid on the home of Haiti's President Jovenel Moïse in the upscale Port-au-Prince suburb of of Pèlerin in the wee hours of July 7, and shot him dead. His wife, Martine, was also gravely wounded. The seemingly professional hit job followed weeks of rapidly rising violence in Haiti. On June 29, three gunmen on motorcycles killed at least 15 people in the Delmas 32 area of Port-au-Prince. Shortly later, gunmen believed to be from the same group carried out the targeted assassinations of prominent women's rights activist Marie Antoinette "Netty" Duclaire and Radio Télé Vision 2000 journalist Diego Charles, who were together at Charles' home in the Christ-Roi neighborhood.

As the US withdraws and the Taliban advance across large stretches of Afghanistan, women are taking up weapons in local militias to defend their villages. In Ghor province, ethnic Hazara women posed for social-media photos wielding rifles and rocket-launchers, pledging to resist by arms a return to "the dark era of Taliban." With US and NATO forces evacuating Bagram Air Base, prelude to a full withdrawal by Sept. 11, the Taliban are rapidly seizing territory. Since launching a spring offensive, the Taliban have doubled their area of control, and now hold nearly 100 of Afghanistan's 407 districts. In retreat, the central government is calling upon civilians to form militias to fight back.

US warplanes carried out strikes June 28 on Iran-backed militias in Syria and Iraq. The Pentagon said the targets were arms depots in the border area used by the militias Kataib Hezbollah and Kataib Sayyid al-Shuhada, which have carried out attacks against US personnel in Iraq for years. "The United States took necessary, appropriate and deliberate action designed to limit the risk of escalation—but also to send a clear and unambiguous deterrent message," Pentagon spokesman John Kirby said. Iraqi militia officials told the Associated Press in Baghdad and the Assad regime's SANA news agency that four militiamen were killed. Kataib Sayyid al-Shuhada vowed retaliation: "We will remain the shield defending our beloved nation, and we are fully ready…to respond and take revenge."
