Nathan Matthews, 28, has been charged with the murder of his 16-year-old step-sister Becky Watts, Avon and Somerset Police said. His girlfriend Shauna Hoare, 21, has been charged with intending to pervert the course of justice.
A teacher who was determined to fight in Syria despite desperate pleas from his family is "appalled" at the brutality shown by Islamic State, a judge has been told.
Jamshed Javeed - who is facing jail after admitting two counts of engaging in conduct in preparation of terrorist acts - said he wanted to go and support the Syrian people in late 2013 and did not then know the truth about Islamic State.
Describing his client as a "thoughtful, studious and mild-mannered" teacher, Charles Bott QC said Javeed was "deeply moved" by images of "extreme suffering" of Syrian people at the hands of the Assad regime.
"The defendant's position is that he did something that he considered right at the time in very particular circumstances that he would not contemplate doing now," he told a sentencing hearing at Woolwich Crown Court.
He said Javeed was "appalled at the indiscriminate brutality" of IS, describing a series of videos showing the murders of Western hostages as "grotesque and barbaric".
The Crown Prosecution Service has confirmed it has authorised Avon and Somerset Police to charge Nathan Matthews with the murder of 16-year-old Becky Watts.
