A teenager from Bethnal Green who fled the country to become a jihadi bride in Syria spoke of her feelings of hopelessness and terror just before her reported death.

Kadiza Sultana, 17, who fled Bethnal Green in the 2015 Easter holidays, was living in Islamic State’s stronghold city of Raqqa and is believed to have died in Russian air strike in May, according to ITV News.

Her distraught family were trying to bring her back across the border to Turkey after she had become disillusioned with life in the war zone.

It is believed Kadiza and fellow Bethnal Green Academy students Shamima Begum and Amira Abase all became so-called “jihadi brides”, marrying IS fighters. Kadiza’s husband was an American national of Somali origin who died last year.

Her sister, Halima Khanom, spoke to ITV News and the interview included phone recordings.

In phone calls to her sister Halima Khanom, Kadiza said: “I don’t have a good feeling. I feel scared. You know the borders are closed right now, so how am I going to get out? If something goes wrong that's it."

Her sister asked how confident she was of escaping and she replied: “Zero.”

Ms Khanom told ITV: “We were expecting this in a way. But at least we know she is in a better place.”

Her lawyer Tasnime Akunjee said: “Leaving IS is like trying to escape from Alcatraz, with a shoot-to-kill order added in.”

“You would move heaven and earth to get any child back from a danger zone, and this family had done all they could and stretched every sinew to get their daughter, their sibling back home.”

The Bethnal Green schoolgirls were among more than 800 Britons believed to have left the UK to militant groups in Syria and Iraq. It is thought that at least 250 have since returned, often with tales of deprivation and cruelty.

Met Police Commissioner Sir Bernard Hogan-Howe told MPs last year the Bethnal Green girls would be unlikely to be prosecuted if they returned unless there was evidence they had committed crimes.
