Congolese President Félix Tshisekedi has vowed to restore government authority in the east, where Rwanda-backed M23 rebels have seized much of the city of Goma and are reportedly advancing south to seize more territory.

The president of the Democratic Republic of the Congo announced a strong response from the Congolese army to the armed attacks by M23 rebels, accusing Rwanda of supporting the rebels and the international and African communities of remaining silent over tensions on the border.

M23's last occupation of Goma was short-lived, and within a year they were a defeated force. This time, things are different.
