From Scottish teen to ISIS bride and recruiter: the Aqsa Mahmood story

Then she went off to pursue violent jihad.

Four days later, Aqsa called her parents as she crossed into Syria from its border with Turkey, on her way to join ISIS.

She has turned up often on social media, exulting the terrorist group’s ideology and calling for attacks against the West. She has posted photos of AK-47s and of executions carried out by ISIS fighters.

And now investigators suspect that she has helped lure three teenage girls from the United Kingdom to Syria to join the terror group.

On what appears to be her Tumblr blog, posts made after Aqsa left Scotland advocate becoming an ISIS bride, summoning the strength to walk away from the family one is born to and joining a new family of jihadists. Some of the posts read like they are authored by a zealot hard bent on indoctrinating others. Some posts are total teenager.

One Tumblr entry mocks the notion that authorities would confiscate passports of those who tried to join ISIS.

“Wow wallahiil Adheeem [I swear to God] biggest joke of this week,” it says.

Stunned and horrified, Aqsa’s family issued a public statement this weekend.

“You are a disgrace to your family and the people of Scotland,” they said. “Your actions are a perverted and evil distortion of Islam.”

“You are killing your family every day with your actions,” they warned. “[We] are begging you stop if you ever loved [us].”

But their daughter isn’t the only one who should shoulder the blame for her possibly joining the terror group, they said, and blasted investigators who they said have monitored Aqsa Mahmood’s social media accounts for months.

The teen’s family wants to know if authorities could have done more to stop the three girls from leaving after at least one of the teens allegedly communicated with Aqsa online.

But the family isn’t talking to reporters, at least right now, because they’re angry about what they perceive as a lack of communication with authorities, their attorney told CNN Monday.

For now the only hints of Aqsa’s next move comes from her social media presence. There’s no apparent clue on her Tumblr page that she could change her mind.

Is she haunted by her mother’s urging that she come home?

When CNN spoke with her parents, her mother pleaded with her daughter: “Aqsa, my dear daughter, please come back. At this moment, I am missing you a lot. Your sisters and brother miss you a lot. My dear daughter, in the name of Allah, please come back. I miss you a lot. I love you. I love you, my dear daughter. Please come back.”

Police have not indicated whether she will be subject to criminal charges if she returns.

All her family has now is hope that they’ll be more convincing than the kind of people she has apparently listened to for quite some time.

On her Tumblr, Aqsa quotes Anwar al-Awlaki, an American-born Muslim scholar, cleric and militant who acted as spokesperson for al Qaeda in the Arabian Peninsula.

He was considered especially adept at recruitment. In September 2011, a CIA drone strike killed him in Yemen.

“Change,” he said, “always in history, depends on the youth.”
