Excerpt:
A girl from the same school attended by girls who went to Syria to join the Islamic State group has been ordered to hand her passport to the High Court.
The 16-year-old's sisters have also been ordered to surrender passports to the tipstaff, an officer of the court.
Judge Mr Justice Hayden made the ruling after hearing the girl may have been "intimately involved" in details of one of the girls who made the journey.
