A Kurdish official said that the Islamic State has executed 19 women. Their crime: refusing to have sex with ISIS soldiers.

The official says the mass execution took place in the radical Muslim group's stronghold, Mosul, Iraq, which ISIS has controlled for over a year.

As Daily Mail reports, the 19 women appear to be yet more victims of the Islamic militant group's "vile sex trade" in which girls (as young as one year old) "get peddled like barrels of petrol":

Meanwhile a UN envoy investigating Islamic State's vile sex trade has said 'girls get peddled like barrels of petrol' and one can be bought by six different men.

She also verified a disturbing ISIS document which suggested the extremists sell the Yazidi and Christian women and children they have abducted, with girls aged just one to nine-years-old fetching the most money. [...]

The sex slaves who somehow escaped Islamic State's clutches have told of how they were forced to marry fighters who physically and sexually abused them.
