The United Nations is piling pressure on countries with foreign nationals in Syria to repatriate them quickly. The UN estimates more than 64,000 individuals, mostly women and children, are currently being held in detention camps in Syria, including nationals from 57 different countries. Fionnuala Ni Aolain is the UN special rapporteur for the protection and promotion of human rights while countering terrorism. She says the women and children in El Hol and El Roj camps in north east Syria face violence, exploitation, abuse, deprivation and treatment that may well amount to torture and those countries whose citizens are stranded in Syria are on a "list of shame".
