Jubilant residents of eastern Congo are pouring into their dusty streets this week.
They're celebrating a decision by the ruthless rebel group known as the M23 to lay down their arms.
Congo's army and rebels had been fighting for more than a year before the government forces soundly defeated the insurgents in their last stronghold.
That's a bit of a surprise for Congolese soldiers, better known for corruption, looting and rape than professionalism.
Photographer Peter Muller, who works frequently for the New York Times, says he's seeing a new discipline in the Congolese armed forces.
Muller marched with Congelese soldiers as they launched their final assault on the M23 rebels in a town called Bunagana.
