Children who were forced to languish in Calais for up to a year as they waited for the Home Office to transfer them to the UK went on hunger strike and in at least one case a child attempted suicide, the Guardian has learned.
Senior officials at the UN Refugee Agency (UNHCR) raised concerns with the Home Office about the health and welfare of at least 35 children held at a centre in Calais in a series of emails seen by the Guardian.
