More than 300m children victims of online sexual abuse every year

First global study of its kind exposes staggering scale' of crime, with one in nine men in the US admitting to the offence

More than 300 million children across the globe are victims of online sexual exploitation and abuse each year, research suggests.

In what is believed to be the first global estimate of the scale of the crisis, researchers at the University of Edinburgh found that 12.6% of the world's children have been victims of nonconsensual talking, sharing and exposure to sexual images and video in the past year, equivalent to about 302 million young people.
