Two troubling photos of a young child violently decapitating a doll were uploaded to Twitter Monday by supporters of the Islamic State terror group, in apparent tribute to the gruesome beheading of US journalist James Foley by members of the Islamist organization last week.

In one of the images, the child, masked and wielding a knife, can be seen holding up a doll dressed in an orange jumpsuit reminiscent of the one wore by Foley during his execution. A black Islamic State flag is seen hanging in the background.

“Teach your children to cut necks, tomorrow there will be a lot of rotten heads,” stated the caption accompanying the picture.

A second photo shows the doll on the ground, its severed head, along with the knife, lying atop its body.

The child’s identity wasn’t immediately clear, nor was the origin of the photo.

A gruesome video released online last Tuesday, showing the beheading of Foley by a man who appears to be a British national, has sparked international outrage and is fueling fears about the increasing numbers of foreign fighters joining the ranks of the Islamic State.

Foley, a 40-year-old American freelance journalist kidnapped in Syria in 2012, was shown kneeling next to a black-clad militant, with a knife to his throat, delivering what is likely a coerced message condemning US strikes on IS targets in Iraq before he is beheaded.

Earlier this month, a photograph of a Sydney-born 7-year-old boy clutching the severed head of a Syrian soldier was posted on Twitter by the boy’s convicted terrorist father, Khaled Sharrouf, an Islamic State fighter. The image was taken in the northern Syrian city of Raqqa.

“This image, perhaps even an iconic photograph … really one of the most disturbing, stomach-turning, grotesque photographs ever displayed,” US Secretary of State John Kerry said of the Raqqa image.

“Of a 7-year-old child holding a severed head up with pride and with the support and encouragement of a parent, with brothers there. That child should be in school, that child should be out learning about a future, that child should be playing with other kids, not holding a severed head and out in the field of combat,” added Kerry.
