The UN refugee agency says it has regained access to two camps in Ethiopia’s northern Tigray region hosting Eritrean refugees.

It said aid had now reached Mai Aini and Adi Harush camps - hosting about 23,000 refugees - but warned that conditions in the camp were still dire.

The UNHCR noted that it only had limited access to the two camps due to the fluid security situation. It said healthcare was unavailable and clean drinking water was running out.

It is now calling for help to safely transfer the refugees to new facilities in Alemwach near Dabat town, 135km (83 miles) away.

The UN agency has also expressed concern over fresh displacement from fighting in Amhara and Afar regions – with an estimated 170,000 people internally displaced. It also observes that more refugees had been crossing into Sudan.

The agency is appealing for more than $164.5m (£118.9m) to assist about 750,000 people in Tigray - and some 120,000 Ethiopian refugees in Sudan.

The conflict, which began in November last year, has forced over two million people to flee their homes, with hundreds of thousands pushed into famine conditions.
