The situation in eastern Democratic Republic of the Congo is becoming increasingly unsafe for both civilians and aid teams, the UN refugee agency, UNHCR, warned on Friday, amid threats by the M23 rebel group that its fighters are about to attack Goma, the regional capital of North Kivu.

According to the agency, some 400,000 people have been uprooted by violence in North and South Kivu since the beginning of the year alone because of intensifying violence and clashes between the M23 rebels, the Congolese Armed Forces and other armed groups.

In an exclusive interview with UN News’s Alpha Diallo, UNHCR’s chief of office in Goma, Abdoulaye Barry, told us what conditions were like in the key city that’s home to two million people.
