Four British siblings have been taken into care after they phoned Childline when they were allegedly shown an Isis beheading video by their parents.
The children, whose identities have not been revealed, told authorities that their parents were supporters of Isis and forced them to watch the disturbing video.
One of the children, a 10-year-old boy with learning difficulties, has been left unable to speak due to the alleged 'physical and emotional abuse', according to court papers.
The oldest of the siblings, an 18-year-old girl, contacted Childline to say they "were kept at home, did not attend school and were kept socially isolated, only being allowed out once in every three weeks".
Rantzen applauded the girl's courage
The High Court judgement says: "The children have complained that their parents expressed support for extremist violence and have expressed anti-semitic, anti-British, homophobic and anti-white views in the home, which the children reject."
Childline founder Dame Esther Rantzen applauded the girl's courage for contacting them.
The siblings in the family of Somali origin from the Midlands – boys aged 10, 14 and 16, and their 18-year-old sister – are now in foster care.
The parents, who cannot be named for legal reasons, have denied the allegations.
