By Yassin Kombi and Sonia Rolley GOMA, Democratic Republic of Congo (Reuters) - Dead bodies lay in the streets, gunfire rang out and hospitals were overwhelmed in east Congo's largest city Goma where M23 rebels backed by Rwanda faced pockets of resistance on Tuesday from army and pro-government militias.

Fighting between Rwanda-backed rebels and the Congolese army continued for a second day in Goma, amid calls by African leaders for an immediate cease-fire.

There are growing international calls for peace talks to end the escalation of violence in the east of the Democratic Republic of Congo. The fate of the economic and trading hub Goma is still unclear. UN officials have said the situation is chaotic with fighting continuing in parts of the city.
