The Democratic Republic of Congo's President Félix Tshisekedi is not taking part in regionally brokered talks aimed at ending the rebel assault on the key eastern city of Goma, state media has reported.

The leaders of DR Congo and Rwanda are meeting at an emergency East African summit in Kenya on Wednesday as M23 rebels, backed by Rwandan troops, tighten their grip on the strategic eastern city of Goma.

The president of crisis-hit Democratic Republic of Congo was set to meet his Rwandan counterpart at an emergency summit on Wednesday, as fighters backed by Kigali appeared on the brink

When M23 rebels swept into the Congolese city of Goma this week, world powers urged them to immediately withdraw. Instead, the Rwanda-backed insurgents are intent on showing they can restore order and govern.

President of the Democratic Republic of Congo said on Thursday that his troopers are fighting an insurgence by the Rwandan-backed militant group M23 which recently captured swaths of land in the east.

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.
