'I felt I didn't belong': A lack of BAME foster carers
Two-thirds of councils in England have a shortage of black, Asian or minority ethnic (BAME) foster carers, according to BBC analysis of official figures.
A fostering expert said this meant many children were growing up without a full sense of their identity.
Shaz, 18, who was cared for by non-Muslims, told the BBC: "I felt like I didn't belong and I had to be white."
Children's minister Michelle Donelan said: "I'm extremely concerned... I think we're letting down children."
