ISIS bride Shamima Begum has told friends she will never name the Brits who also joined the terror group, it has been reported.
Begum, 22, said this week she was not a threat as she begged to return to the UK.
She also said that she could even help fight terrorism.
However, it is believed Begum has promised to stay silent on other Britons who also fled the UK to join ISIS in Syria, saying it is a "red line".
A source close to her case told The Sun on Sunday: “She’s made it clear she won’t name any British IS fighters she met in Syria.

“Some have survived and the intelligence is so patchy that her evidence would be invaluable. But for her it’s a red line. It won’t help her chances.”
Begum, who at the age of 15 fled her home in East London to join ISIS, said on Wednesday joining the terrorist organisation was a "mistake".
She said she would "rather die than go back to ISIS" as she denied allegations of her helping ISIS pursue their extremist cause.
The teenager, who had her UK citizenship revoked by the Home Office on national security grounds, said she was "completely sorry to anyone who is affected by ISIS".
It comes months after losing her Supreme Court bid to return to the UK.
Begum has given birth to three kids - who have all since died.
She now lives in a Syrian refugee camp and on Wednesday she told Good Morning Britain she was “dumb” to join ISIS.
Wearing western-style clothes, she added: “I did not want to hurt anyone in Syria or anywhere else in the world."
She denied any allegations of her helping ISIS, while she tried to defend her actions saying: "At the time I did not know it (so-called Islamic State) was a death cult, I thought it was an Islamic community I was joining.
"I was being fed a lot of information on the internet by people."
She said she thought she was "groomed and taken advantage of and manipulated into" travelling to Syria.Read More Read More
