Migrants arriving at France's Calais "Jungle" since demolition of the camp will not be resettled by the local authorities, the government representative in Calais said.
A resettlement centre that has been sending migrants on to reception centres across France as part of the shutdown operation was now closed, Prefect Fabienne Buccio said.
"It is not Calais' role to receive all the migrants of Europe. We do not want to create a vacuum. We have asked (those newly arrived) migrants to disperse."
Earlier in the day, a group of about 100 migrants, mainly young people, were seen filing past a group of riot gear-clad police who have been overseeing the camp clearance since Monday.
Teenagers gathered at a makeshift church in the Calais 'jungle' just days after authorities declared the operation to clear the camp over.
Those still left after the demolishing of the 'Jungle' camp were seen wrapped in blankets as they prepared to sleep rough.
The UK's French ambassador, Sylvie Bermann said the destruction of the Calais 'Jungle' will encourage refugees to seek asylum in France.
