Quick Summary

Regional forces in northern Ethiopia's Tigray seized control of three airports and clashed with federal troops on September 23, signaling the start of a major offensive after months of growing tensions following a peace deal that ended the 2020-2022 conflict. This new fighting threatens to trigger wider war due to deteriorating ties between Ethiopia and Eritrea, Sudan's civil war, and tensions over Red Sea access. The article focuses on how the Tigray People's Liberation Front (TPLF) alliance with other armed groups aims at overthrowing Prime Minister Abiy Ahmed's government, potentially drawing in neighboring countries like Eritrea and complicating regional stability further.

Story summary

As of October 10, 2026, Ethiopian forces regained control of Adigrat, a strategic border city near Eritrea, after reports of an earlier incursion by Eritrean troops. This development follows two weeks of escalating conflict in Ethiopia’s Tigray region where Tigrayan rebels seized airports and clashed with federal troops in neighboring regions like Afar and Amhara. Ethiopian Airlines suspended flights to three Tigray airports amid the fighting.

Ethiopia accused Eritrea of an "all-out invasion" in a letter to the UN Security Council, while Eritrea denied this claim. Both nations have mobilized their military along their shared border, heightening fears of regional war involving neighboring countries like Sudan and Djibouti. Reports suggest up to 8,000 Eritrean soldiers may have crossed into Tigray recently.

The renewed conflict threatens to undo progress made since a 2022 peace deal ended two years of civil war in Ethiopia. Diplomatic tensions between Addis Ababa and Asmara over territorial disputes persist, complicating efforts at de-escalation. International observers are concerned about the potential for wider regional instability if fighting intensifies further.

🔮 The strikes, which also targeted a cargo vessel at sea near Odesa, follow Tuesday's bombardments with missiles and drones that knocked out power to swathes of Ukraine, a week before US-brokered peace talks were set to resume.
🔮 While Ramaswamy, 41, faced sharp backlash over his ad campaign, Trump continued to back the Republican candidate and accused the media of a coordinated attack to undermine his chances. US Vice-President J.D. Vance similarly defended his “good friend” Ramaswamy while on the campaign trail in Ohio. But Democrats swiftly criticised the ad, as did some Republicans including outgoing Ohio governor Mike DeWine, who could not run again due to term limits. In the ad by Ramaswamy’s campaign, Acton’s estranged mother – Donna Arthur – said her daughter has “lied her entire life” and should not be allowed to become governor. Acton issued a statement in October saying that she and her brother had “endured abuse, hunger, and neglect” as children. “Between the ages of 10 and 12, I was sexually abused by her husband, while my birth mother did nothing to protect me,” she said.
🔮 It was a striking Democratic gain in a state President Donald Trump carried by more than 16 percentage points in 2024 and where the race had initially been expected to be safely Republican.
🔮 The top Democrat in the US House of Representatives vowed on Nov 3 he would use his expected majority to go after corruption, in an election when alleged grift by President Donald Trump has been top of voters’ minds.
🔮 In an interview with Fox News, Trump said Democrats would send legislation he considered “insane” to his desk and that he would veto it.
🔮 Three-term Republican Texas Governor Greg Abbott lost to Democratic state Representative Gina Hinojosa in a stunning upset that ends the Republican Party’s three-decade hold on the governor’s office, US media projected on Nov 3.
🔮 Talarico defeated the state’s Attorney-General Ken Paxton, a close ally of President Donald Trump who survived impeachment and years of scandal, NBC News and CBS News projected.
🔮 Democrat Kathy Hochul was projected to win a second full term as New York’s governor, defeating Republican Bruce Blakeman in a race polls showed her leading throughout the campaign.
🔮 Trump says he will accept results of US midterm elections Erica L. Green and Tyler Pager AI generated
🔮 But after initially saying Trump was “cautiously optimistic,” the mood music changed as Democrats looked increasingly likely to deal the president a bruising setback that could upend his last two years in power.

Narrative

The peace process began to unravel after splits emerged within the TPLF, and a hardline faction of the party reasserted control over the region, kicking out an interim administration. Most recently, the TPLF formed an alliance with six other armed groups from across Ethiopia, including former enemies from the war, aimed at overthrowing Prime Minister Abiy Ahmed's government. It is not clear how many members of the alliance were involved in clashes on Wednesday but Ethiopia is home to many heavily armed regional groups.
