A woman has told Sky News she fears her estranged husband will try to take their son to Syria, after a court granted the radicalised man unsupervised access despite her concerns.

Speaking exclusively to Sky, the woman - who requested anonymity for her personal safety and that of her child - says she has been let down by the French state.

She chose to speak out in an effort to raise awareness of her case.

Her comments come as the French government faces growing calls to overhaul its intelligence agencies and change the way they share information with police and the judiciary, after the recent terror attacks in Paris, Nice and Rouen.

The estranged husband is understood to be one of more than 10,000 French citizens logged as suspected jihadists on the 'S Files' - the country's intelligence watch-list.

"During my pregnancy I could see his radicalisation. It happened progressively, not overnight ... " she told Sky News.

"He cut himself off from the world … night and day he watched propaganda videos.

"There were lots of little things that showed he was radicalised."

Although the judge agreed to put the child's name on a "no travel" register, the mother said she had "no confidence" it would be sufficient protection given the man's brother had already successfully travelled to Syria, despite himself having an S file.

Samia Maktouf, the lawyer who will appeal the court's decision, said the case was far more than a custody battle, and was instead an example of pervasive failures the French government has not addressed.

"We are in front of a judge who has nothing - no idea, no information, let me say no culture, no background about terrorism - this is a failure, I want this to change", she said.

"The judge has trusted a radicalised man, without having any other information from intelligence or any other services ... she decided it alone."

Ms Maktouf is also representing victims of the Paris attacks last year, suing the French state for intelligence failings.

Last month, a parliamentary inquiry launched in the wake of those attacks, concluded a major overhaul of the country's security infrastructure was needed.

It recommended merging the six separate intelligence agencies into a single entity.

But just a few weeks after its publication, another terrorist attack - the murder of Father Jacques Hamel in Saint-Etienne-Du-Rouvray, whose funeral will be held later in Rouen Cathedral - put intelligence failings back under the spotlight.

The 19-year-old assailants, Adel Kermiche and Abdel Malik Petitjean, were both known to authorities, and Kermiche was wearing an electronic tag.

The French government has instigated a state of emergency and also increased armed security presence in crowded public places nationwide.

But there are growing calls for tougher measures against suspected jihadist sympathisers, even if they are yet to commit an offence.

While much of the pressure is coming from the right-wing opposition, there is also support from some within France's Muslim leadership.

In an interview with Sky News, Slimane Nadour, spokesman for Paris Grand Mosque said: "We demand strong action against these people.

"Strong action is to imprison them. To send them back to their countries."

He added: "We need really extreme action against these people, and extreme action about all radical speech and radicalism in France as a whole."
