Residents of the besieged city of Goma, in the east of the Democratic Republic of Congo, say they are gripped by fear as gunshots continue to ring out around their homes, days after rebel forces claimed they had taken over.

The scene is the result of the invasion of Goma on January 27th by M23, an armed group under the control of Rwanda, Congo’s neighbour, which abuts the city. Paul Kagame, Rwanda’s president, has escalated a crisis whose origins go back decades.

Rwanda-backed rebels claimed on Monday they captured eastern Congo’s strategic city of Goma, the hub of a region containing trillions of dollars in mineral wealth that remains largely untapped.

Bodies are lying on the streets. Medical staff in overwhelmed hospitals are treating hundreds of wounded civilians against the backdrop of gunfire and mortar fire.

Rwanda's President Paul Kagame said he agreed with the U.S. government on the need for a ceasefire in eastern Congo but gave no indication of bowing to calls for Rwandan troops and the M23 rebels they support to withdraw from Goma.

Fighting with M23 rebels in eastern Democratic Republic of Congo left six United Nations peacekeepers dead, UN officials said Saturday.

M23 rebels claim they now control the Congolese city of Goma—an act Congo's government described as a 'declaration of war.'

President Paul Kagame said Rwanda was ready for "confrontation" as he rejected criticism over his backing for M23 rebels who were pushing south on Thursday in eastern Democratic Republic of Congo after capturing the major city of Goma.

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.

"We are asking all Goma residents to go back to normal activities," said Corneille Nangaa, head of Alliance Fleuve Congo, the political coalition backing the M23, just two days after heavy fighting subsided, leaving bodies in the streets and the city cut ...

In June last year, Rwanda's government spokesperson Yolande Makolo hit out about the presence of mercenaries in eastern DR Congo, saying it was a violation of the Geneva Conventions, which prohibit the use of hired combatants. In response, Congolese government spokesperson Patrick Muyaya dismissed what he called Rwanda's perennial complaint.
