 According to Mirza Dinnayi, founder of the German-Iraqi aid organization Luftbrücke Irak, ISIL registers "every slave, every person under their owner, and therefore if she escapes, every Daesh [ISIL] control or checkpoint, or security force - they know that this girl ... has escaped from this owner".For over a year after the girls were first enslaved, "Arab and Kurdish smugglers managed to free an average of 134" slaves a month.But by May 2016, an ISIL "crackdown reduced those numbers to just 39 in the last six weeks, according to figures provided by the Kurdistan regional government".
