The Ethiopian government has urged Tigrayan forces to surrender, as federal troops battle to take control of the region.
This comes as parliament has voted to strip dozens of MP’s from Tigray of their immunity from prosecution.
The fighting, which began over a week ago, is reported to have killed hundreds of combatants on both sides.
Ethiopia’s federal government is sounding confident. Defence Minister Kenea Yadeta said it would not be long before the leaders in Tigray, from the Tigray People’s Liberation Front (TPLF) party, were on trial.
He talked of appointing an interim administration in areas taken by federal troops.
But with all telecommunication switched off it is hard to verify what has been happening since the fighting began.
Both sides have been speaking of success and are also accusing the other of committing atrocities.
What is clear is that civilians are suffering. Thousands have fled to Sudan.
The UN fears a major emergency may be brewing and says its negotiating with both sides to enable humanitarian corridors to be opened.
