Her mother said: 'I just wish I could go there myself and fetch her'

As many as 30 Swedish girls are thought to have

A teenager, who disappeared from her home last month, has informed her mother that she has arrived into Syria and that she has gone to join an Al-Qaeda affiliated group.

The 15-year-old, who has yet to be named, rang her mother from the Syrian city of Homs, informing her of her decision and that she was travelling to a new city to join Jabhat al-Nusra.

It is likely that she will travel north, towards the city of Idlib, where Jabhat al-Nusra has gained ground through its alliance with several other rebel groups.

The Swedish school girl reportedly left her home on 31 May and secretly traveled to Syria. She has since informed her mother that she is going to join the Al Qaeda affiliated group Jabhat al-Nusra

Speaking to the Swedish newspaper Aftonbladest, her distraught mother recalled her feelings after she learnt what had happened to her daughter.

'I cannot describe how terrible this is and I just wish I could go there myself and fetch her,' she said.

As many as 30 other Swedish girls are thought to have travelled from their homeland to Syria or Iraq in order to join jihadi groups.

At least one Swedish girl, known as Umm Ayyoub, is believed to be living in Raqqa with at least one of the three East London school girls, who disappeared to Syria last February.

Damaged but not raised to the ground, Idlib was seized by rebel fighters from Assad forces last March

Jabhat al-Nusra is an Al-Qaeda affiliated group, who fight exclusively in Syria and are led by Abu Mohammed al-Joulani.

In recent months, the jihadi group has been fighting as part of a rebel alliance known as 'The Army of Conquest'.

The alliance, which also includes the Salafi based Ahrar al-Sham, captured regime held Idlib last March.

Idlib was seen as a major gain from the alliance after months of stalemate against Assad forces in northern Syria.

The rebel coalition has since moved further north-west, cutting off regime held supply lines and capturing the city of Jisr ash-Shugur, sparking jubilant celebrations among the militants.
