A woman who was allegedly promoting Islamic State (Isis) on social media, wanted to marry Islamic State executioner Jihadi John. Zafreen Khadam, 32, is accused of disseminating terrorist propaganda on online messaging services Twitter and WhatsApp, and encouraging others to commit acts of terrorism.

Counter-terrorism officers began investigating Khadam in January 2015 following concerns about "extremely graphic and disturbing" content on her Twitter account. A court heard that she had opened as many as 14 different twitter accounts during a space of two-months, one of which had the handle 'Jihadi Princess.'

Khadam, who is from Sheffield, South Yorkshire, shared jihadi lectures, IS propaganda magazines, speeches and videos, including footage of graphic executions carried out by the reviled British extremist Mohammed Emwazi, who became a poster boy for foreign jihadis.

Khadam was allegedly intending to flee to Syria to become a jihadi bride after she exchanged 2,000 messages with an Isis (Daesh) fighter in Syria called Abu Muhammed. In the messages she tells him she "wanted to marry him, wanted to live the IS life and wanted to move to Syria," adding that while Jihadi John was "kind of scary" she would "marry him". One message to the IS fighter is alleged to have read: "I hope Islamic State rises and comes to the west."

She posted a number of graphic videos including footage of IS fighters burning a Jordanian pilot alive, with the caption: "good riddance - enjoy" and another of a man having his throat cut. Others showed Kurdish fighters being paraded through the streets in cages by IS militants, while another showed a man being burnt alive.

She is also alleged to have shared a document encouraging people to spread ISIS propaganda and advising on 'security precautions' for potential terrorists who want to avoid being caught. The defendant liked a video depicting young children doing military training in preparation to become fighters for the miltiant group. The chilling footage shows a child saying into the camera: "I will be the one who slaughters you".

After her arrest Khadam, who described herself as an activist, told police she was carrying out "undercover research" into the operations of the terror group and claimed she "genuinely wanted to go to Syria for humanitarian reasons" so she could try and find "the truth about what was happened in the country".

Khadam denies 10 counts of dissemination of terrorist publications, Mirror Online reports. The trial continues.
