When Islamic State (IS) militants took control of Syria and Iraq in June 2014, the entire Yazidi population in Sinjar were immediately in grave danger. The Sunni Muslims of IS believed Yazidis were infidels and should either convert to Islam or be killed.

On 3 August 2014, 5,000 Yazidis were killed on the first day of the genocide. For those who survived that night, the only escape route was to climb Mount Sinjar in the blistering heat, with no shelter or food, and pray to be rescued.

Mirza Dinnayi convinced Iraq\u2019s president to supply three helicopters and began evacuating 50,000 Yazidis, who were stranded on top of the mountain in a race against time. Mirza shares his experience with Sarah Ehrlich.
