“This is a parallel state — a state within a state, with its own rules and religious courts — where allegiance to Islam comes ahead of fealty to France.”

Jews are spat upon.

Hundreds of known jihadists are living in Saint-Denis, while 1,700 are believed to have returned to France after fighting for IS in Syria, with 15,000 terrorism suspects in France.

For over a decade, my colleagues and I warned of this, for which we were smeared, mocked, and libeled — to this very day. Everything, as we predicted, has come to pass. Despite this, we are still marginalized and demonized. Slaughter in the cause of Islam is swept under the rug as “mental illness.” Jihad terror is now an opportunity for dawah, to spread Islam, the religion of peace. Two dead children in Toronto, Nice, Manchester, Berlin, etc. affect no reflection or change in narrative. It is some crippling societal sickness.

And it’s only going to get worse.

For Paris, it is just a matter of time.

Andrew Malone ventured into the Paris suburb of Saint-Denis for a week, a neighbourhood is home to as many as 300,000 illegal immigrants

At the World Express cafe, groups of men argue in Arabic. On side streets, men smoke shisha pipes and talk — again, in Arabic — on every corner. Women shop in veils and scarves, always accompanied by a male relative.

As a white European, I attract odd looks. When I take out my mobile phone for a photograph, a young man jumps in front of me, waving his index finger in my face, shouting: ‘La! La! La!’ (No! No! No!)

Yet this is not an exotic, far-flung destination. This is France. Moreover, this is Paris and only six miles from the Eiffel Tower.

The reason for all this activity — in an area which even the most optimistic estate agent would struggle to sell as ‘cosmopolitan and bohemian’ — is quite simple: immigration on a mammoth scale.

The area in question is called Saint-Denis in the north-east of the city, where the Basilica holds the resting places of many French kings and queens.

Recently, it was reported that this sprawling district now holds as many as 300,000 illegal immigrants, many of whom rely on crime or the ‘black economy’ to make money. The official legal population in Saint-Denis is estimated at 1.5 million.

Not only that, according to French parliamentarians in a new report that’s causing much anguish across the nation, as many as 420,000 legal residents here are living ‘below the official poverty line’.

The scale of the problem grows each day. An estimated 80 migrants arrive in Paris every 24 hours — 550 a week.

Many head for Saint-Denis because of its closeness to transport links, including the railway lines heading towards the North coast, and Britain.

Migrant camps, set up in tents along the Seine in this area of Paris, were destroyed by the police in May, with the occupants who didn’t get away taken for processing in detention centres after a raid.

But there are still campers everywhere, as well as people sleeping on the streets.

There are an estimated 135 different nationalities in Saint-Denis, most extremely poor, including an estimated 600,000 Muslims from North African or sub-Saharan African backgrounds.

‘The challenge,’ says Paris senator Philippe Dallier, is ‘to prevent Saint-Denis becoming a huge ethnic ghetto of two million inhabitants within 20 years.’

Bon chance, monsieur — as they don’t say in this teeming quarter, where speaking Arabic is more useful than French.

Having spent several days in Saint-Denis, it’s clear to me that the area is already lost to France — to the rule of French law, equality, religious freedom, and even access to the streets by the police themselves.

Indeed, this is a parallel state — a state within a state, with its own rules and religious courts — where allegiance to Islam comes ahead of fealty to France.

Police have reportedly admitted the area is a ‘no-go’ zone, and will only drive through the areas armed and four to a vehicle

Here, I saw a woman walking in full face veil — illegal under a French law introduced to promote integration. No one batted an eye.

People bought and sold drugs openly. What law there is takes place inside Sharia courts, where Islamic leaders dispense the same forms of justice practised in the countries from which many here fled.

And where, as I discovered, other faiths and religions are being driven from the area.

When helicopters flew overhead in training for the Bastille Day celebrations earlier this month, one man pretended to shoot at them with a machine gun.

Another pushed him away and pretended to fire a shoulder-mounted missile, tracing the missile with his hand towards its targets and shouting: ‘Boom!’ Everyone laughed.

Further down the street, there was a flurry of activity. A woman was surrounded as she opened a huge bag full of phones, shoes, sunglasses and handbags — clearly stolen from tourists or Parisians. The goods were quickly sold and the crowd melted away.

Police have reportedly admitted the area is a ‘no-go’ zone, and will only drive through the areas armed and four to a vehicle.

Meanwhile, politicians on the Left try to deny the problems: Anne Hidalgo, Socialist Mayor of Paris, announced she was going to sue Fox News, the Trump-supporting Right-wing U.S. TV channel, for claiming that there were ‘no-go areas’ open only to Muslims.

The suit was never filed, but it is surely impossible to deny that the number of impoverished migrants in France is causing a dangerous social dislocation.

The appalling attacks in November 2015 by home-grown Islamic State killers shone a pitiless spotlight on the problems that can grow out of immigrant ghettos.

The carnage started close to the Stade de France, the national sports stadium, which is in Saint-Denis, where some of the killers sought refuge after the attacks.

One hundred and thirty people died in a single night of violence involving suicide bombings and Kalashnikov fire around bars, cafés and venues, including the Bataclan concert hall.

Five days after the attacks, the suspected mastermind was run to ground in an apartment by hundreds of security officers.

‘The police had no idea who anyone was, and were pretty much shooting on sight because everyone was a suspect,’ a local who witnessed the raid told me.

‘The terrorists had rented rooms with no questions asked, and were left to get on with their crimes.’

At the time, Manuel Valls, the prime minister, spoke of a ‘geographical, social and ethnic apartheid’ and that ‘these last few days have underlined a lot of evil that is gnawing at our country’.

The 2016 Bastille Day attack in Nice left 87 dead — including the terrorist — and 458 injured, when a truck ploughed into revellers on the Promenade des Anglais.

Since then, as I discovered, in many ways the situation has worsened, although thankfully there has not been another major terrorist attack.

There are around 350 known jihadists living in Saint-Denis, while 1,700 are believed to have returned to France after fighting for IS in Syria, with 15,000 terrorism suspects in France.

In Saint-Denis itself, there is a record number of mosques — 160 official ones, and many more unofficial — compared with 117 Catholic churches and 60 Protestant. Yet it is the unauthorised mosques — set up in basements and garages — that the authorities fear the most.

‘The radicalisers use these hidden places of worship to influence the young and impressionable,’ said a veteran police officer who has worked in Saint-Denis for more than two decades.

He added: ‘Salafists (followers of an extreme form of Islam) impose the rule of religion, so we can have very little influence. These radicalisers are the ones who motivate the young towards terrorism.’

Much of the money-raising activity comes from drug-dealing by gangs, many of them Muslim. At one high-rise block of flats not far from where I was staying, the scale of the operation was evident.

Like a department store, different drugs are sold on different floors. Moroccans and North Africans sell hashish for ten euros a bag on the third floor.

On the next floor up, two West African youths — one with his hair dyed pink, the other blonde — were dispensing skunk marijuana for 20 euros a bag.

Further up were older black Africans selling rocks of cocaine at 20 euros for a small plastic wrap. Above, heroin was being sold, and there was also, apparently, a room set aside for injecting.

At this point, I told one of the men I was a journalist and asked whether we could have a chat.

A chunky character in a red Ellesse sports shirt, he was relaxed, smiled at me and said politely to me in English: ‘No — go.’ I went.

Most blocks seemed to have the same operation, with youths guarding the front doors, ‘spotters’ on the streets opposite for signs of police or other gangs, and the drugs held and sold inside.

Rabbi Yisroel Belinow, 50, is either a fool or very brave. As I walked near a mosque, I saw him looking out of his window. His home was firebombed in 2009, and a kosher restaurant next door burned down.

He’s since watched other Jews flee the area, and his dying father begged him to leave before it was too late. He came down to speak to me, but declined my invitation to stroll around the streets.

‘My parents came here from Russia and Poland,’ he told me. ‘When I was a kid, there were the usual jokes between children; we made fun of each other, but there was always a limit. I could go anywhere I wanted whenever I wanted.’

‘The problem is people coming to France and wanting to change it. And it’s worse because they want to force people to change. I know I look different. The hatred is obvious — people spit when you walk past.

‘I respect this country because I was born here. I respect the laws of this country. I respect Christmas even though it has nothing to do with being a Jew.

‘Now they won’t let Christmas happen. France has existed for thousands of years. If I didn’t like those laws, I would move to another country.

‘It wasn’t always like this. In the beginning, [French people] wanted to help. The charity these people [recent migrants] were shown was tremendous. But you wake up and realise pretty soon that this works one way only. Many people have left.’

Mireille Knoll, an 85-year-old Jewish grandmother and Holocaust survivor, vowed never to leave Paris, but she was stabbed to death in her apartment in March.

Two men in their 20s have been charged with her murder, one of whom Mrs Knoll’s family say was a Muslim neighbour they had known since he was a boy.

The dead woman’s son said: ‘At first we weren’t sure [the killing] was due to anti-Semitism. We waited for police to say it, and now we know the truth.’

While only a few hundred attend weekly mass at the Basilica here, thousands of Muslims stream into the area’s mosques for Friday prayers — so much so that, in a rare intervention, the authorities banned them from praying in the streets as well.

Women suffer the most. Not far from the drug dealers outside the station, I visited a women’s refuge set up by Ghada Hatem, a senior gynaecologist, who says almost one in five of her patients have been victims of female genital mutilation (FGM) — the barbaric ritual of cutting the sexual organs of young women.

Now a specialist in the repair of such intimate mutilation, Hatem, who hails from Lebanon, says she is in daily contact with ‘women who tell me about the horrors they experience at home’.

Sarah Oussekine, who has an Algerian background and who runs a group called the Voix d’Elles Rebelles (Voice of the Female Rebels) in Saint-Denis, says: ‘When you ask girls why they are starting to wear the headscarf — and many more are — they tell you it is an act of faith, but actually when you dig deeper, they have to wear it to stay safe.’

All this, of course, has led to a toxic, incendiary atmosphere in this Parisian suburb — with Muslim groups countering that they suffer harassment, police violence and religious and racial discrimination.

Riots erupted in February last year after a young black man was allegedly sexually assaulted with a baton by police officers.
