Fighting to the finish in the Democratic Republic of Congo.

Congolese forces unleash their fire power against M23 rebels as they seek to end a 20-month revolt.

Now there are hopes for peace as the army captures the last hilltop stronghold of the rebels near the border with Rwanda and Uganda.

After the fight the M23 announced it would disarm and pursue political talks.

U.S. Envoy to the region Russ Feingold welcomes the news.

(SOUNDBITE) (English) U.S. SPECIAL ENVOY FOR THE GREAT LAKES REGION OF AFRICA, RUSS FEINGOLD SAYING:

"In a region that has suffered so much this is certainly a significant positive step in the right direction."

The M23 is just the latest manifestation of simmering anger with Kinshasa among ethnic Tutsis in eastern Congo.

The real test will be whether the government and rebels can reach a lasting political deal.

The Congolese army will take up arms again if necessary.

(SOUNDBITE) (French) FARDC SPOKESMAN, ARIU OLIVIER, SAYING:

"It is not the end of the war because there are still other groups who still have weapons on Congolese territory and we will also disarm them by force if they do not want to comply peacefully."

But still, the hope is for peace in a country where millions have died in nearly two decades of violence.
