Just two out of the 600 females who have fled from Western countries to join ISIS have returned home from Syria, figures show.

Experts say an increased number of women and girls are travelling to join the terror group, dazzled by a warped notion of adventure, sisterhood and feminism.

But, following a move which is much more final than many realise, only two of the so-called jihadi brides have made it out of the warzone.

By comparison, European government figures which monitor the returns estimate that almost one third of male jihadists have escaped from the clutches of ISIS or are on their way back from Syria.

According to researchers, many women and girls are unable to escape from the warzone - even if they realise they have made a mistake - due to the prescriptive life enforced upon them.

Amid a huge demand for jihadi brides due to the ever-increasing number of foreign fighters joining ISIS, the females are married off almost immediately after arriving in Syria.

Once embedded, they are kept under the watchful eye of their husbands and the group's commanders, only allowed to travel with a male chaperone or a group of other women. Experts say those who dissent risk a lashing or, sometimes, worse.

Sara Khan, a British Muslim whose group Inspire campaigns against the dangers of extremist recruiters, said: 'The lives of those teenage girls are very much controlled.'

Among the two women who did return from Syria was Dutch teenager Sterlina Petalo, who travelled to the Middle East in 2014 after converting to Islam.

Sterlina, who became known by the name Aicha, married a Dutch jihadi in the ISIS stronghold of Raqqa but returned after her mother reportedly picked her up from the Turkish border.

After arriving home, she was immediately arrested on suspicion of joining a terror organisation, but her family, lawyers and prosecutors have refused to discuss the case.

She was released from custody last November and has not been formally charged.

The second woman returned home after reconsidering her decision only after just a few weeks.

The 25-year-old Briton, whom police have not named, had taken her toddler son all the way to Raqqa when she decided she had made a mistake and called home.

She made her way back into Turkey and her father met her there. It is not clear how she was able to travel the 150 miles from Raqqa to the Turkish border city of Gaziantep.

Back in Britain, she was detained and is now free on bail pending formal charges.

HOW WESTERN WOMEN ARE DEFY JIHADI BRIDE STEREOTYPE Women joining ISIS are increasingly likely to be highly-educated and from comfortable backgrounds with romantic notions of adventure, according to a report. But the women often become quickly dispelled by the harshness of life with the terror group. The paper, compiled by the Institute for Strategic Dialogue and the International Centre for the Study of Radicalisation at King's College, said very little was being done to explain why there had been an 'unprecedented surge' to ISIS. The report, entitled 'Till Martyrdom Do Us Part', looked at the social media activity of more than 100 Western women who are thought to have joined the militants. Like Western men who have joined ISIS, the women felt socially and culturally isolated, believed Muslims were being persecuted and were angry that nothing was being done about it, it said. They were also attracted by an idealistic view of religious duty, a sense of sisterhood, and the romance of the adventure. However, life under ISIS was far from the image they saw portrayed online. Conditions were harsh and some became widows at a young age. The report concluded there was a need for 'counter-extremist' messages to be aimed specifically at women, detailing how life under ISIS is far removed from the idealised view. Advertisement

Yesterday, a former female commander also spoke to Sky News, having fled the terror group just a few days ago.

The 22-year-old, who mentored the three British schoolgirls who fled from Bethnal Green earlier this year, is currently in a secret location and is hoping to return home.

Joana Cook, a researcher at King's College London who studies the links between women and jihad, said the mystery surrounding the return of the females makes it difficult to say whether others could follow their path.

'There are clearly many human smugglers working within Syria right now, helping Syrian civilians escape the violence, and I wonder if there is a similar, perhaps even growing market, for those trying to escape after joining ISIL,' she said.

The networks that bring the women into Syria are increasingly organised around the extremists' dream of building a nation of multinational jihadis, meaning European girls are particularly prized.

The doggedness of jihadi methods for recruiting girls can be seen in the case of Amelia, a 14-year-old girl from France's Alpine Isere region.

Amelia was first contacted on Facebook by a French fighter in January 2014. Within a month, she had agreed to go to Syria and marry the man, who identified himself as 'Tony Toxiko.'

After she was turned back by airport border police in Lyon on her first attempt, 'Tony Toxiko' persuaded another French adolescent girl to join him in Syria.

Amelia, meanwhile, ran away from home to Belgium, where an imam performed a religious ceremony that wed her to a different man, an Algerian jihadi.

She returned to France homesick and pregnant, just long enough to speak to investigators building a case against a middleman who helped her run away.

This winter, Amelia managed to deceive her family and left again — making it to Syria with the Algerian fighter, who is more than twice her age.

Sebastien Pietrasanta, a French lawmaker working on a program to de-radicalise young people, said: 'It's particularly difficult for these families.
