The lawyer representing jihadi bride Shamima Begum has said her family is considering “all legal avenues to challenge the decision” by UK authorities to revoke her British citizenship.

Nineteen-year-old Begum—who has remained defiant about running away from her London home four years ago to join ISIS—is in a Syrian refugee camp with her newborn son.
