Ethiopia invokes self-defence at UN as Eritrea rejects invasion claim

Ethiopia has told the UN Security Council it is taking measures in self-defence against Eritrea, accusing its neighbour of sending troops into northern Ethiopia. The letter, dated Friday and reported by the Associated Press on Saturday, invokes Article 51 of the UN Charter but does not specify what military measures Addis Ababa has taken.

Claims and counterclaims

Foreign Minister Gedion Timothewos alleges that Eritrean infantry and mechanised units crossed the border and occupied parts of the north. The letter did not identify the occupied areas or provide supporting evidence, AP reported. Eritrean Information Minister Yemane Gebremeskel has instead accused Ethiopia of aggression over its pursuit of sovereign access to the Red Sea. Reuters separately reported the competing statements on Friday. Neither government’s account alone establishes the full scale of the deployments.

Why this is a new escalation

The formal UN notification moves the confrontation beyond last week’s diplomatic rupture. AP also reported Ethiopian federal police entering Mekelle after opposition forces withdrew, while a conflict monitor recorded Eritrean troops crossing at Zelambesa earlier in the week. The risk is renewed fighting affecting communities still recovering from the 2020–22 Tigray war, with implications for security around the Red Sea.
