Hundreds of refugees who are living in makeshift tents in the Calais camp nicknamed the 'Jungle' have been told that they have to leave within the next four days or face eviction.
French authorities have given between 800 to 1,000 people until Tuesday evening (7pm UK time) to leave the southern part of the French site which has become home to thousands of refugees and migrants.
There are an estimated 4,000 people living in the 'Jungle' at the moment, many of whom have fled war, poverty and persecution, in war-torn states such as Syria and Iraq.
Pascal Froehly, who volunteers for the relief organisation Caritas, spoke of his concerns of heightened tensions being created if bulldozers move in to level the site.
He said: "I find it extremely annoying and unfair to move these people away from what they have created, including churches, shops and restaurants," the Press Association reports.
Froehly said the plans to move them to heated containers elsewhere in the camp offered the migrants and refugees no chance to socialise, adding: "It's just a bed for them."
Mayor of Calais Natacha Bouchart said the dismantling of the camp would keep migrants and refugees away from activists bent on causing disruption.
She said it was a "sensitive situation" that required "necessary firmness". And she added the conditions endured at the Jungle were "unworthy of human nature".
Plans to move people to heated containers in the camp and centres around France were announced by Prefect Fabienne Buccio, the top official in France's northern Pas-de-Calais region.
Buccio said this month: "It's time to tell the migrants of Calais who live in undignified conditions and give Calais an image that isn't dignified either, that we have a solution for each of you."
The news comes just days after 145 celebrities called up David Cameron to help save the children based at the 'jungle' camp.
Actors Idris Elba, Helena Bonham Carter, and Benedict Cumberbatch are among the stars to sign an open letter to the Prime Minister asking the Government to step in and allow unaccompanied children living in the Jungle to be reunited with their families in the UK.
Meanwhile, Eurotunnel has asked the British and French governments to reimburse it £22 million (29 million euro) for lost revenue during the cross-Channel migrant crisis.
