The headteacher of the school attended by three teenage girls believed to have travelled to Syria to join Islamic State has said police found no evidence that the missing students were radicalised there.

Metropolitan Police officers are in Turkey as the search continues for three missing schoolgirls believed to have fled to Syria to join Islamic State.

The family of a British woman who travelled to Syria to marry an Islamic State fighter have branded her a “disgrace” and expressed anger that she may have tried to recruit three missing schoolgirls to the militant group.
