'We don't know what comes next': Fears after rebels take key city in Democratic Republic of Congo

On the doorstep of Goma - the site of the UN's biggest peacekeeping mission in the world - there are signs of surrendered soldiers and fierce battles.

As we walked on the road in front of the United Nations' main base, we stepped around fatigues, rounds and helmets once belonging to the Congolese army fighting the Rwandan-backed M23 rebels.

The rebels now control the strategic city of Goma after fighting for the border post with Rwanda. It sits south of the swathes of mineral-rich mining territory the rebels have been seizing through last year.

We see them packed on the back of trucks still marked by the FARDC logo of the Congolese army.

I ask one man watching from the side of the road what he makes of this extreme shift.

"This is bad!" he says to me discreetly on the side of the road, with our car as cover from the prying eyes of the junior M23 soldiers.

"My family is not good. I am not good - we don't know what comes next."

Small groups are meeting the rebels with cheers and clapping.

We cannot tell if it is relief from the Congolese state or a necessary precaution for many who do not want to leave their hometown on the cusp of a new administration.

But before they can settle in and set up a local authority, M23 have time to stop and humiliate their former enemy.

Not just the Congolese troops, but the Romanian mercenaries fighting alongside them.

MONUSCO, the United Nations's peacekeeping group in the DRC, brokered an evacuation convoy for the paid fighters to go to Rwanda with trucks full of Uruguayan peacekeeping troops watching as M23 led the handover through their newly-captured border.

As the Romanian men pass through in a single file, they are chastised by M23 spokesperson Willy Ngoma who taps them mockingly one by one.

"Come on soldier!" he said. "You were fighting for money - we were fighting for our life!"

I corner him as he flags the buses through - could you have come this far without Rwanda's support?

He tries to keep busy, and after the fourth time I repeat the question, he yells into my face in French:

"We are a Congolese army, we are Congolese! We fight for a fair and noble cause - we are Congolese. We are not helped by Rwanda!"

It will take more than a feverish denial to undermine the widely known support of Rwanda for M23 - one that has been condemned at the highest levels of the United Nations and senior diplomats from around the world.

As the "Welcome to Rwanda" sign gets closer, the last Romanian mercenary limps across with a wounded leg flanked by a UN security advisor and an Indian medic.

A surreal sight of a man heading home after fighting a war in a foreign country surrounded by Congolese families fleeing the war at home.
