ISIS has posted a video of what appears to be a young American boy — who says he traveled from the US to Syria two years ago — threatening President Donald Trump, according to The Daily Beast.

“My message to Trump, the puppet of the Jews: Allah promised us victory, promised you defeat,” the boy, who identifies himself as Yousef, says to the camera, The Beast reported. “This battle is not gonna end in Raqqa or Mosul. It’s gonna end in you lands.”

“My father’s an American soldier who fought the mujahideen in Iraq,” Yousef, who appears to be scripted, says to the camera in perfect English, The Beast reported.

Yousef is thought to be 10 years old, according to Mirror UK, citing Site Intelligence Group, a group investigating the video's authenticity.

"It’s significant that he identifies his father as a former US soldier and makes an overt threat to Trump,” Georgia State University Professor Mia Bloom told The Beast. “The use of children in this way is intended to show the conflict is multi-generational. That even the kids are radicalized.”

Bloom also told The Beast that while this is the first time that they've used an American child in a propaganda video, ISIS uses more than 20 children a month for operations on the battlefield.

ISIS has consistently used children to carry out suicide attacks and to mutilate captured prisoners. They've also been known to use children as human shields, and even female ISIS fighters have used their own children as human shields.
