Migrants in Calais have been given four days to leave the so-called 'jungle' camp, ahead of its demolition.
The migrants, many of whom are Syrians or Iraqi refugees, have been told to move to nearby containers or welcome centres around France.
Those who refuse to leave will be forcibly removed by French police.
The order affects up to a thousand migrants who live in the southern sector of the camp.
Migrants have built up a makeshift community there, with shops, cafes, churches and mosques.
