The Islamic State has used a 10-year-old American boy to issue a threat to US President Donald Trump saying that US will face defeat under the hands of the terror group.

Yusuf, the boy who is used in the propaganda video filmed by IS says, “My message to Trump, the puppet of the Jews. Allah has promised this victory and he has promised you defeat. This battle is not going to end in Raqqa or Mosul, it is going to end in your lands. By the law of Allah we will have victory, so get ready for the fighting has just begun.

The boy who seemed to be reading from a script said that he moved to the IS two years ago from the US with his mother and shared that his father was an American soldier he fought in Iraq.

He further called US a state of ‘non-believers’. The seven minute ling video showed Yusuf reciting the Quran.

They are among thousands of children trapped in Raqqa, according to Unicef figures, as the besieged city is bombed by the US-led coalition and advancing troops.

IS frequently publishes gory images claiming to show alleged massacres by coalition bombing, which Yusuf said happens every night.

The ten year old said, “Do you think that we’ll be finished? Never! We will remain until the day of judgement.”

“All children in Syria, regardless of their location or their families’ affiliation must be protected at all times,” a UNICEF agency representative in Syria said.
