Residents in eastern Congo's largest city, Goma, woke up on Monday morning uncertain about who is in control of the city, which Rwanda-backed rebels claimed to have captured.

M23 rebels in the Democratic Republic of Congo were reported to have taken the key eastern city of Goma in fierce fighting with government forces that sent streams of refugees fleeing area communities.

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.

The Democratic Republic of Congo’s government says the Rwanda-backed rebels’ advance constitutes a “declaration of war."

Goma is on the brink of falling after M23 rebels and Rwandan troops entered the eastern Congolese regional capital. The border between DRC and Rwanda was closed, and Kenyan President William Ruto convened an extraordinary East African Community summit amidst escalating uncertainty.

Residents of eastern Congo's largest city of Goma greeted the arrival of Rwanda-backed rebels with trepidation on Monday, some staying indoors and others coming out to cheer in what one called a "show" of happiness.
