The two Austrian teenage girls who changed their minds after wanting to become “poster girls” for ISIS terrorists in Syria could end up being prosecuted if they return to their homes.

In April, Samra Kesinovic, 17, and friend Sabina Selimovic, 15, left a note for their parents that read: “Don’t look for us. We will serve Allah, and we will die for him.”

The girls are believed to be married, pregnant and living in the ISIS-controlled city of Raqqa in northern Syria, according to Central European News.

Austrian police have compiled a dossier about the girls’ links with terrorist groups. When contacted about whether charges are pending against the girls, a police spokesman declined to comment, according to CEN.

But Andreas Venier, an Austrian criminal lawyer, said if the girls’ claim that they had gone to support the jihadis was true, it would be a criminal offense.

“Participation in a terrorist organization is a punishable offense in Austria which doesn’t just mean standing on the front line and pulling the trigger, it also includes supporting or supplying information to the Islamic State in Syria or Iraq. If the girls are found to have been involved with the terror group, they could face a prison sentence of up to five years even as minors,” he said.

He said prosecutors also would look at whether the girls had been coerced or intimidated by others into making the move to Syria.

“You obviously cannot say that every trip to Syria results in taking part in terrorist activities. Guilt has to be proven in every case rather than assuming involvement in such organizations,” he said.

For weeks, social-media accounts believed to belong to the girls had been posting pictures and information that seemed to suggest the young duo enjoyed living a life of terror.

The pictures showed the two girls smiling and wearing their new Muslim garb, sometimes while flanked by armed fighters. Some of the images appeared to show the girls carrying weapons.

Still, some of the images may have been faked, Austrian authorities have said.

The girls, who reportedly believed propaganda put to them in a local mosque run by radical preacher Ebu Tejma, evidently changed their minds when they realized the realities of the brutal ISIS regime. But the teens apparently don’t feel they can flee because too many people now associate them with ISIS savagery

Karl-Heinz Grundboeck, a spokesman for the Interior Ministry, said: “The main problem is about people coming back to Austria. Once they leave, it is almost impossible.”
