French officials have said the rate of demolition at the Calais "Jungle" migrant camp will be scaled up today.
Larger machinery will move in after authorities declared the clearance of the camp complete, with 5,596 people evacuated since the operation began on Monday.
However, Save The Children said it was "extremely concerned" about minors who had not been registered as the site went up in flames.
Several large fires started tearing through caravans, tents and shelters in the centre of the camp a little before midday on Wednesday, the third day of the operation to clear it.
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.
