Renewed fighting between Ethiopian federal forces and Tigrayan rebels has left dozens of civilians dead or injured, including several children, raising fears of a fresh humanitarian crisis in northern Ethiopia. The violence, which began on September 23, has intensified across parts of the Tigray region. Medical workers at a hospital in Tigray on Tuesday said children were being treated for serious injuries, including severe leg wounds and amputations, following heavy shelling. A drone strike on a displacement camp in western Tigray on Sunday reportedly killed eight people, including a child and an aid worker, while at least six others sustained serious injuries. Meanwhile, shelling in the cities of Maychew and Alamata between September 26 and 28 critically injured at least 44 civilians, including 33 children, according to a medical source. The Ethiopian federal forces have since pushed back the Tigrayan offensive and captured the regional capital, Mekelle, after leaders and fighters of the Tigray People's Liberation Front withdrew from the city. Members of the Ethiopian National Defence Force are stationed at Mekelle's Alula Aba Nega International Airport on Tuesday. The renewed conflict has heightened concerns about a return to the devastating Tigray war of 2020 to 2022, which is estimated to have claimed about 600,000 lives.
