Shamima Begum has lost her latest bid to overturn a decision by the UK government to strip her British citizenship
The Court of Appeal ruling means she remains in Syria with no chance of return to the UK, Ednews reports citing the BBC.
In her ruling, the chief justice says while the decision in Begum's case is "harsh", it could be argued Begum is "the author of her own misfortune"
Begum became known the world over when in 2015, aged 15, she left her home in London to travel to Syria to join Islamic State group
The now 24-year-old's lawyers brought a bid to overturn a 2023 decision at the Court of Appeal, with the Home Office opposing the challenge
The Home Office argued the "key feature" of Begum's case was national security.
