Shamima Begum, a British citizen who went to Syria and joined PISSI, has won in court the right to return to the UK and challenge the decision to cancel her citizenship and exile her.

Her participation in a terrorist organization may well justify criminal charges and punishment -- if convicted in a fair trial. But it is wrong to use exile as a punishment, and wrong to punish people in any fashion without a fair trial.

More about the issue.

She is being held prisoner by the Kurds of Rojava, but they may have to transfer her (and other British PISSI supporters) to Assad or Iraq if they can't return to the UK soon.
