(Bloomberg) — Ethiopia’s northern Tigray remains unstable as fighting continues in several areas, including the outskirts of the regional capital, Mekelle, according to the United Nations.

More than 4.5 million people in the war-torn region need emergency food assistance, the UN’s Office for the Coordination of Humanitarian Affairs said in a report compiled after two missions to the province last month.
