M23's last occupation of Goma was short-lived, and within a year they were a defeated force. This time, things are different.

Rwanda-backed rebels claim they have captured eastern Congo’s largest city, Goma, as the United Nations describe a “mass panic” among its 2 million people and Congo’s government say the rebel advance was a “declaration of war.

Kenyan President William Ruto said Monday that the presidents of Rwanda and Congo have agreed to attend a meeting Wednesday to discuss developments in eastern Congo, where M23 rebels say they have seized control of Goma on the Congo-Rwandan border.
