A 15-year-old Swedish girl has been captured in Syria by ISIS after running away from her Swedish foster home with her boyfriend, Swedish media reported Monday.
The Swedish foreign ministry remained tight-lipped about the case, confirming only minimal details.
"We have been informed that a Swedish minor is in Syria. We are in contact with family members," ministry spokesman Gabriel Wernstedt told AFP, refusing to disclose any other details in the case.
Swedish daily Expressen and local paper Boras Tidning reported that the 15-year-old girl, whose name was not disclosed, disappeared from her foster home in Boras, near the southwestern town of Gothenburg, on May 31.
She and her 19-year-old boyfriend reportedly traveled to Syria via Turkey, and were recruited on arrival by a Al-Qaeda-linked group.
The couple were captured by ISIS troops in Aleppo in early August, the media reports said. They were married in a Muslim ceremony in Stockholm earlier this year, without their parents' knowledge.
The daughter has called her parents twice while in captivity, after a woman secretly loaned her a cell phone, the reports said.
She told her parents the couple was waiting to have their marriage confirmed by ISIS.
"It is really a critical situation. She said ISIS would decide whether their marriage was legitimate or not, and he had to swear allegiance to ISIS," the girl's father told Boras Tidning.
"If they approved the marriage they would be moved to Raqqah, which is an even worse place than Aleppo. Otherwise she would probably end up with a group of women in Manbij (a town north east of Aleppo)," he said.
According to Expressen, the girl is six months pregnant.
