Fire blazes through the Grande-Synthe migrant camp.
A fire burned through the Grande-Synthe, a migrant camp near Dunkirk in Northern France.
Local sources said violence broke out about 19.30 after Afghan immigrants, recently arrived from the Calais immigrant camp, were unhappy that they were living in dormitory accommodation while the Kurds occupied most of the 300 cabins.
"There is nothing left but a heap of ashes", Michel Lalande, prefect of France's Nord region, told reporters.
"Already we are seeing migrants return to the Calais area - all with the same goal; to reach the United Kingdom by whatever means possible and that usually means on the back of a truck".
A spokesman at the regional prefect's office said that 165 people had already been taken to makeshift shelters, Reuters reported.
Last October, the population swelled after the closure of the sprawling "Jungle" camp at Calais around 40 kilometres (25 miles) away.
Riot police intervened. One migrant was knocked over by a auto on a highway outside the camp and was in a critical condition. Other aid groups are planning to distribute meals Tuesday to migrants in the gymnasiums and anywhere else they are found around town.
"It all started with a fight between the Afghans and the Kurds".
Hours later, flames lapped the sky in a blaze the prefecture said was apparently linked to the clash. "I just have only this paper that says I'm a refugee in France".
People in France - and the rest of Europe - have grown increasingly hostile to the huge wave of refugees that has been coming to the continent over the last few years. We don't have any place. we don't know what to do.
Authorities in France are in a race against time to find accomodation for around 1,400 migrants after a camp was destroyed by fire.
Humanitarian groups said the original camp was filthier and more unsafe than a huge makeshift camp in Calais, about 30 kilometers to the west, that was dismantled by the state in October. "We lost everything", he added.
