Rwanda-backed rebels who captured eastern Congo’s largest city said Thursday they want to take their fight to the far-off capital, Kinshasa, while Congo’s president called for a massive military mobilization to resist the rebellion with his Defense minister rejecting calls for talks.

The Rwanda-backed M23 armed group vowed Thursday to "continue the march of liberation" to the DR Congo capital Kinshasa, as its fighters made further advances in the mineral-rich east of the country.

The rebel leader whose fighters have captured Goma, the biggest city in eastern Democratic Republic of Congo, has vowed to continue their offensive all the way to the capital, Kinshasa. Corneille Nangaa, who heads an alliance of rebel groups that includes the M23, said their ultimate aim was to topple President Félix Tshisekedi's government.
