Rwanda-backed rebels who have captured eastern Congo’s largest city say they plan to take their rebellion to the capital and seek to gain political power.

In view of the restive situation in the country, Congo's President Félix Tshisekedi vowed a vigorous and coordinated response to push back the rebels while reaffirming his commitment to a peaceful resolution.

The latest fighting has heightened an already dire humanitarian crisis in the region, forcing half a million people from their homes since the start of the year.
