A woman who left Britain as a teenager to join the Islamic State (IS) cannot return home, the Supreme Court in London ruled Friday.

Now aged 21, Shamima Begum wants to come back to Britain to challenge the decision by former British Home Secretary Sajid Javid to strip of her British citizenship for joining the IS militant group.

In a unanimous decision, five judges at the Supreme Court ruled that she cannot return to London to fight her citizenship case.

Begum and two other east London schoolgirls left Britain for Syria in February 2015 to join the IS. They married jihadi fighters and lived under IS rule. Currently, Begum is in a camp controlled by armed guards in northern Syria.

Last July the British Court of Appeal ruled that the only fair way forward was to allow Begum into Britain as she could not effectively appeal against the citizenship decision from the camp in northern Syria.

The Supreme Court rejected the Court of Appeal’s decision.

After the ruling, Javid said he strongly welcomed the court’s decision, saying that “any restrictions of rights and freedoms faced by Begum were a direct result of her extreme actions.”

However, the British human rights organisation Liberty said the ruling has set an extremely dangerous precedent.
