A series of pictures posted on Instagram show men who have reportedly been caught trying to escape from northern Iraq wearing dresses, bras and make-up.
Reports say the men and even young boys were caught by Iraqi forces. Under Sharia law, which ISIS partially adheres to, women are prevented from fighting.
Jihadists are believed to be terrified of being killed by a female because they think it will stop them getting their 72 virgins in heaven. But men and boys as young as 13 - have been given powerful machine guns and are expected to join the cause.
The photographs were released just five days after it emerged that three men from the region were accused of homosexuality and publicly beheaded by a sword-wielding ISIS executioner.
Iraqi troops and militia are battling to push ISIS back from the area with support from a US-led coalition and Iran.
