Congo's leader has called on young people to enlist in the army to help fight Rwanda-backed rebels attempting to seize more territory in the country's conflict-battered east.

As an East African bloc urged an immediate ceasefire in eastern Democratic Republic of Congo, Rwandan-backed M23 rebels who seized the city of Goma extended their advance on Wednesday, and Congo said it planned a campaign to recover lost territory.

Local sources said Kigali-backed fighters were advancing on a new front and had seized two districts in South Kivu province, after the rebel group’s capture of most of Goma, the capital of North Kivu.

The rebels, which Rwanda denies supporting, have long been funded at least in part by the illicit mineral trade.

Many Congolese see the rebel advance as an invasion of their country by a foreign power in an attempt to seize land and Congo’s valuable rare minerals.

The group's capture of most of Goma, the capital of North Kivu province, is a dramatic escalation in a region that has seen decades of conflict involving multiple armed groups.

Kagame's comments clearly suggested that he wants South Africa to back off from DR Congo, where its military involvement dates back to the late 1990s. It first joined the UN's peacekeeping mission, Monusco, following the end of the racist system of apartheid in 1994.
