Fighting between DR Congo's military and M23 rebels killed more than 900 combattants in the country's restive east before the insurgents were routed, a senior military official told AFP on Monday.
"Between 20 May and 5 November, the... (army) had 201 dead and 680 wounded. On the M23 side, there were 721 dead and 543 captured, including 72 Rwandans and 28 Ugandans," said General Jean-Lucien Bahuma, a senior commander in the North Kivu region where the fighting took place.
Three UN peacekeepers were also killed.
The M23 rebels, one of many armed groups operating in the mineral-rich but impoverished east of the Democratic Republic of Congo, were routed by the national army, who were backed by a 3,000-strong special UN intervention brigade.
The UN has accused Uganda and neighbouring Rwanda of backing the M23. Both countries have denied the charges.
Hopes for a political deal to end the latest bloody insurgency to plague eastern DR Congo were dashed on 12 November, when the government and the defeated insurgents failed to sign a much hoped-for peace deal.
