Democratic Republic of Congo troops have returned to the eastern city of Goma, although rebels who occupied the city for nearly two weeks remain close by.
Reports from the area said about 600 army troops entered Goma Monday, while government officials also started to return.
The M23 rebel group pulled out of the city on Saturday after the brokering of a regional peace under the plan, the rebels were to withdraw 20 kilometers from the North Kivu provincial capital. But residents and officials said some of the rebels remain on the outskirts of town.
The rebels maintain that they have not broken the agreement.
M23 is made up of former rebels who were integrated into the Congolese army before deserting earlier this year, complaining of discrimination and poor treatment.
