In Ethiopia, central government troops and fighters from the TPLF People's Liberation Front, which ruled the Tigray region, are at war. According to the UN, more than 14,500 people have fled the clashes in neighboring Sudan so far. The African Union (AU) has called for an immediate ceasefire in northern Ethiopia. AU chief Moussa Faki Mahamat appealed on Tuesday to the conflicting parties to immediately stop the fighting and “respect human rights and guarantee the protection of the civilian population”. Ethiopian government troops have meanwhile taken the strategically important airport in Humera in the north-east of the country on the borders with Sudan and Eritrea, as the state-affiliated television station Fana TV reported. Hundreds of people have now been killed in air strikes and fighting on the ground in the breakaway region of Tigray.
