Rwandan troops have begun withdrawing from eastern Democratic Republic of Congo after joining forces with the Congolese army last month to hunt down Rwandan Hutu rebels.
Witnesses near Goma saw hundreds of Rwandan soldiers marching on foot across the border Wednesday, back into Rwanda. Other troops were traveling in Rwandan military trucks.
Several thousand Rwandan troops deployed to eastern Congo last month to help Congolese forces drive out the Hutu rebels, some of whom took part in the 1994 Rwandan genocide.
Congolese military officials have said the joint operation achieved most of its goals. The U.N. peacekeeping mission in Congo says hundreds of Hutu rebels originally from Rwanda have turned themselves in.
Officials also say the operation marked unprecedented cooperation between the two countries after years of tension.
