United Nations aid agencies have called for an immediate temporary ceasefire in Ethiopia following more than two weeks of fighting between the army and regional forces in Tigray.
They have had no access to the conflict zone and want humanitarian corridors to be set up.
The UN fears hundreds, possibly thousands of civilians have been killed.
More than 30,000 refugees have arrived in Sudan – many are hungry and frightened, over half of them are children.
The UN has appealed for funding and is planning for the possible arrival of around 200,000 refugees over the coming months.
