Gunfire rang out early on Monday across parts of Goma, the largest city in eastern Congo, hours after Rwanda-backed rebels said they had seized the city despite the United Nations Security Council's calling for an end to the offensive.

Rebels say they have taken control of the city of Goma in eastern Democratic Republic of Congo, although this has been denied by the government. Residents shared videos of M23 rebels patrolling Goma's main streets following a lightning advance against the Congolese army on Sunday that saw tens of thousands of people fleeing neighbouring towns.

The M23 militia, funded and directed by Rwanda, said it had seized the city of Goma, terrifying its people, many of whom sought shelter there after fleeing the rebel advance.
