An Iraqi soldier survived a mass execution carried out by Islamic State militants (Isis) by dropping to the floor and pretending to be dead.
Islamic State (Isis) militants killed up to 770 men in mass executions at five locations in Tikrit after seizing the city in northern Iraq in June, Human Rights Watch has claimed.
Ali, a 23-year-old soldier who survived of one of the shootings, identified one of three newly discovered sites.
He was captured on 12 June with thousands of other men at 11 am as they tried to flee along the main road from a military base.
Other soldiers and officers had advised him to wear civilian clothes to try to avoid detection by Isis fighters.
Ali said he was among prisoners held in a shipping container in a palace compound in the city before being taken out in a group of 10 at about 5 pm, where the men were lined up to be shot with pistols one after another.
