About 2.3 million children in Ethiopia’s northern Tigray region are cut off from humanitarian assistance as violence continues, the UN has warned.

“Protecting these children, many of whom are refugees and internally displaced… must be a priority”, said the UN’s children’s agency Unicef.

Despite deals with the Ethiopian government, humanitarian agencies say they are being denied access to Tigray.

Government forces have been battling Tigray fighters since 4 November.

The government says it is in control of the region and the conflict is over. But Tigray People’s Liberation Front (TPLF) says it is still fighting on various fronts.

Hundreds, even thousands, of people are thought to have been killed in the conflict, while about 50,000 have fled to neighbouring Sudan
