The stench of burning plastic hung over the "Jungle" migrant camp on Wednesday as dozens of riot police moved in for a third day to demolish the shantytown in northern France.

Charred husks of shacks and smoldering logs marked the spots where half a dozen shelters were burned down overnight in the camp on the outskirts of the port city of Calais.

A French court on Thursday gave the green light to plans to evacuate hundreds of migrants from the notorious "Jungle" camp in the northern French port of Calais.

Activists working in the camp had asked the court to stop the evacuation of the southern half of the "Jungle," with many of the migrants wanting to stay near the entrance to the Channel Tunnel, the gateway to their ultimate goal of Britain.

French President Francois Hollande and his Prime Minister Manuel Valls are under open attack from the left flank of the governing Socialist party, with leading figures accusing the pair of crippling the country.

With 15 months to go until the presidential election at which Hollande is expected to seek a second term in power, Martine Aubry -- a powerful ex-minister and daughter of former European Commission chief Jacques Delors -- led the charge.

A Jewish teacher in France is to face trial in April for allegedly lying to police by claiming he was attacked by three Islamic State jihadists, a prosecutor said Thursday.

The teacher, Tsion Sylvain Saadoun, is charged with "false accusation of an imaginary crime", said Brice Robin, prosecutor in the southern city of Marseille.

French special forces have been deployed in Libya to fight the Islamic State group, France's Le Monde reported Wednesday -- triggering an official probe into a possible leak of classified information.

Le Monde said special forces and members of the DGSE external security service were present in Libya for "clandestine operations" against IS jihadists, thought to number several thousand in the chaos-scarred country.

A Jewish teacher in France who claimed he was attacked by Islamic State jihadists was taken into custody on Wednesday, accused of lying to police.

The man invited the press to his house in Marseille in southern France the day after the supposed attack in November, saying he had been beaten by three men claiming to represent the jihadist group.

Migrant protesters were due in a French court Monday after occupying a cross-Channel ferry, as charities warned thousands could be affected by plans to evict half of Calais' "Jungle" refugee camp.

A court in Boulogne-sur-Mer was to deliver a verdict in the case of two activists and six migrants who took part in last month's protest in the northern port city of Calais, urging Britain to allow asylum seekers in.

French police raided the headquarters of the far-right National Front on Wednesday over allegations the party was fiddling European Parliament expenses to pay for assistants, a source close to the investigation said.

The raid at the party's headquarters in Nanterre, west of Paris, came a day after police searched the home of founder Jean-Marie Le Pen, as well as the office of his secretary and an accountant linked to the party.

Since that awful night in November that jihadist gunmen stormed the Bataclan concert hall in Paris, Alexis has not been able to go into a cinema or even "sit in the window of a restaurant" never mind go to a rock gig.

The 26-year-old Internet moderator who survived the massacre by playing dead in the moshpit after the Eagles of Death Metal fled the stage, even avoids passing anywhere near the building in which 90 fans were killed, though he lives close by.

Groups representing the victims of the November 13 jihadist attacks in Paris have begun providing chilling testimony to parliamentary investigators, denouncing what they called "an atrocious lack of preparation" for an emergency in which 130 people lost their lives.

"We have a thousand questions and we expect answers," said Georges Salines, head of one of several victims' associations represented Monday at the first of a series of hearings to be held over coming weeks.
