“I am upset,” his mother Ltefaji Hoxha told NBC10 at her house in Margate in the first confirmation outside of court filings that the 25-year-old is in Syria fighting for the group also known as the Islamic State. “No good. I’m very upset.”

Hoxha, 25, was identified in filings for the federal case against David “Daoud” Wright, who was convicted last year on terrorism charges and is serving 28 years in prison. The Atlantic first identified Hoxha as Abu Hamza al-Amriki.

A terrorist by that nom de guerre made waves in May 2017 when he appeared in an ISIS propaganda video. In that video, he calls on “lone wolf” terrorists to carry out attacks on targets in the United States.

“Liberate yourself from hellfire by killing a kafir,” Abu Hamza al-Amriki said in the video, which showed him in battlefield fatigues and kneeling in front of rocket launchers.
