The UN said at least 49 of those kidnapped had been killed and up to 900 remain missing
Up to 900 men and boys who fled their homes near Isis’ former stronghold of Fallujah remain missing in Iraq after being abducted by a militia accused of torturing, shooting and beheading civilians.
The United Nations said captives who have since been freed by the paramilitary group reported a litany of war crimes and atrocities after they sought refuge from battles between Isis and Iraqi forces last month.
Those abducted had been among 8,000 civilians who fled the village of Saqlawiyah, north of Fallujah, as fighting intensified on 1 June.
The Office for the High Commissioner of Human Rights (OHCHR) said the refugees headed towards what they believed to be government forces hailing them with loudspeakers but arrived to find a line of militia fighters behind the Iraqi flags bearing the standard of Kataaib Hezbollah.
