• Who are the M23 rebels and why is there fighting in DRC?

Dead bodies lay on the streets and explosions and gunfire echoed across the largest city in eastern Democratic Republic of the Congo (DRC) on Tuesday, as fighting continued to rage between the army and Rwanda-backed M23 rebels.

Residents reported continuing gun and mortar fire in Goma, the capital of North Kivu province and a regional humanitarian hub for displaced people, after M23 fighters entered the city on Sunday.
