CALAIS, France (AP) -- Demolition crews are set to move into a sprawling slum camp in Calais, where thousands of migrants dream of getting to Britain, as French authorities try to close an embarrassing and often shocking chapter in Europe's migrant crisis.
Closing the camp — known as "the jungle" — would be the most dramatic step by the French state to end Calais' years-long migrant problem, which has transformed the port city into a high-security tension point, fueled far-right sentiment and defied British and French government efforts to make it go away. Critics contend that closing the camp may not solve the problem.
An eviction deadline Tuesday for the camp's southern sector came and went, with migrants and humanitarian groups trying to stave off bulldozers via a legal complaint, a letter to the interior minister and public pleas that included a dose of star power. British actor Jude Law paid a visit last weekend and 260 French figures signed a petition against destroying the camp.
Its short-term fate is in the hands of a judge at the Administrative Court in Lille, likely to decide Thursday on a request by humanitarian groups to postpone the destruction of the densely built-up southern sector of the camp.
Calais reflects the tensions arising over migrants around Europe, with solidarity going toe-to-toe with bitter anti-migrant sentiment.
Calaisians have mostly learned to live with migrants in their midst. But tensions rose when the population of travelers spiked last fall to 6,000.
An increasingly vocal backlash against migrants is punctuated by militia-style violence. Truckers have grown exasperated or fearful of increasingly bold tactics by migrants trying to sneak a ride. Businesses and small shopkeepers have protested damage to commerce and what they say money can't buy — image. Riot police moved in to patrol the camp this month.
The area targeted for destruction is dotted with rickety shops, cafes, places of worship and schools, built by aid groups and the migrants, most of whom traveled from conflict zones like Syria, Iraq or Afghanistan, or came to escape human rights abuses or poverty in African nations.
A sense of anxiety mounted in the camp ahead of the court ruling. The prefecture, the state authority in the region, estimates the number of migrants living in the southern sector from 800 to 1,000, but humanitarian groups contend the figure is more than 3,000, including hundreds of unaccompanied children.
"Obviously, they are scared and concerned about what is going to happen," said Ed Sexton, of Help Refugees, one of numerous British associations working in the camp. "The people have been here months, living in terrible conditions, but they don't want their shelters destroyed."
Authorities cited security and sanitation concerns for the closure, and the increasingly tarnished image of Calais. The city of nearly 80,000 takes pride in drawing tourists to its Opal Coast but is taking collateral damage in the migrant crisis because of its location — with a major ferry port, Eurotunnel rail system and truck traffic crossing the English Channel.
Weary travelers come to Calais driven by a dream — circulated among migrants, peddled by smugglers — that they will find peace and prosperity in Britain. Lacking papers, they have to sneak across the Channel, and at least 20 migrants have died trying since late June, according to the prefecture.
Camp residents were offered the choice of being sent to temporary welcome centers around France, or staying in one of 125 heated containers set up last month in a fenced-in area behind the camp. However, only several hundred beds remain.
"It's inhuman to live in the jungle. But certain associations, certain billionaire stars are telling us to leave things alone," the head of the region, conservative Xavier Bertrand, said during a visit last weekend. "That's enough. The jungle must be evacuated."
Humanitarian workers predicted that those who refuse to leave would shelter in small groups elsewhere around Calais and the coast.
"You're basically going to scatter a lot of people," said Maya Konforti of the association Auberge des Migrants.
Nearby Belgium, concerned about an influx of Calais evacuees, has installed border checks.
Another filthy camp known as a haven for smugglers, near Dunkirk, is being relocated to a more hygienic site with heated tents under the supervision of Doctors Without Borders.
The prefecture, which announced plans to raze the camp on Feb. 12, said bulldozers would not touch the camp's makeshift churches, mosques and a just-opened school. Facing criticism of the eviction order, Interior Minister Bernard Cazeneuve softened the ultimatum this week, saying the evacuation would be "progressive."
Authorities view the razing of much of the camp as a turning point for Calais — a far from certain outcome. used during its three-year existence by some 68,000 refugees
A Red Cross-run camp in nearby Sangatte — used during its three-year existence by some 68,000 refugees — was shut down in 2002. Afterward, hundreds moved up the coast to set up small "jungles" around Calais.
Authorities periodically razed them, then opened a state-sponsored day center in April with showers, plugs to charge phones and a meal distribution center. That lured migrants chased from inside the city, who pitched camp nearby.
Authorities allowed the camp to grow, and it evolved into a squalid slum town with some amenities of urban life that injected a sense of solidarity and conviviality into migrants' bleak lives.
