At least 770 killed in Goma, east DRC, in fighting with Rwanda-backed M23

Rebels had captured the city in January in major escalation of 10-year-old conflict

At least 773 people were killed in eastern Democratic Republic of the Congo's largest city of Goma and its vicinity this week amid fighting with Rwanda-backed rebels who captured the city in a major escalation of a decade-long conflict, Congolese authorities have said.

The rebels' advance into other areas was slowed by a weakened military that recovered some villages from them.
