A fire has destroyed most of a migrant camp in northern France after fighting between rival groups injured five people, leaving officials scrambling on Tuesday to rehouse around 1,700 people.

The Grande Synthe camp of tightly packed wooden cabins, set up just over a year ago, was 70 percent destroyed by the blaze on Monday night after clashes between Iraqi Kurds and Afghans, Michel Lalande, a top regional official, told Reuters.

The Kurds originally formed a majority, but the population of the camp, near Dunkirk on the Channel coast, has swelled with the arrival of many Afghans.
