Leonora Messing, 19, fled to Syria four years ago where she met Jihadi Martin Lemke and became mother to his two children

A father has revealed his heartache after finding out his 15-year-old daughter has become the third wife of a Jihadi in Syria and is mothering his two children.

Leonora Messing fled her home in Sangerhausen,a town in Saxony-Anhalt, Germany, to join the Islamic State (IS) in Syria four years ago before wedding Jihadi Martin Lemke known as Nihad Abu Yasir.

He is a technician for IS repairing computers and phones but there are claims he worked for the feared religious police.

And sweet photos have emerged showing Leonora embracing her father Maik Messing, 47, just one month before she disappeared.

He has now written a book titled Leonora about his experience of losing his daughter to the terror group.

Maik Messing (pictured right) says his daughter (pictured left age 15) 'does not belong' in Syria and has now written a book titled Leonora describing how he lost his daughter to the terror group. Here they are pictured a month before she left their home in Sangerhausen, Saxony-Anhalt, Germany

It is 'clear that she is not just a young girl who was seduced' but also an 'offender', he told CEN. He was made aware of her new relationship when Nihad called to tell him his daughter was safe.

But Maik added how she 'does not belong there', it is not her 'country or war' and her family lies with him in Germany.

His daughter was a class representative and read for residents at a nursing home which meant there were never any warning signs.

She regularly spoke to her father and told him how her husband (pictured right) had allegedly bought a slave for £647 and other conversations would cover baking bread in Syria or the gold jewellery on her wedding day

But then when Leonora joined Syria in 2015, she spied on German IS women during their 'Islam lessons' in the city of Raqqa to then report back to their husbands about how they were settling in.

And despite this she even kept in contact with her family in Germany and often told her father about the gold jewellery she received on her wedding day, the war in Syria, the horrors of the IS as well as everyday things like baking bread.

Leonora told him about her husband buying a slave for an alleged £647.

But following the defeat of IS, Leonora is now living in a Kurdish prison camp in north-east Syria and hopes to return to Germany.

Police in Germany are now investigating to what extent Leonora was involved in IS crimes and this week her family home in Germany was searched by cops.

She spoke earlier this year about her 'naivety' of arriving in Syria and having only been converted to Islam for two months.

Initially 'everything was good' as the IS had the money and she could stay at home to cook or clean. But when IS lost Raqqa, she was forced to move home every week.

Leonora said she fled with husband Nihad, his second wife Sabina, 34, who is also from Germany and her children.

They were caught by Syrian Democratic Forces and taken to the Kurdish camp.

Leonora said she twice tried to flee but was caught each time by her husband.

She said: 'I want to go back to Germany to my family, back to my old life. I know it was a big mistake.'

This comes after Shamima Begum's heartbreaking appeal to come back to England and her loss of British citizenship after she fled Bethnal Green, East London, in the same year to join IS in Syria and went on to marry a Dutch fighter.

Maik Messing's book aims to describe 'the seductive power of IS and its terror' and can be bought on Amazon here.
