United Nations secretary-general António Guterres has welcomed the African Union’s appointment of three high-level envoys to help resolve the conflict in the Tigray region of Ethiopia. AU chairperson president Cyril Ramaphosa has appointed former presidents of Mozambique and Liberia, Joaquim Chissano and Ellen Johnson-Sirleaf, and South Africa’s Kgalema Motlanthe as envoys. More than 30-thousand people have fled Tigray for Sudan to escape fighting between national and regional forces. Guterres says the UN supports efforts towards peace and stability in Ethiopia.
