(Vocativ) – ISIS has eulogized their “youngest Islamic State martyr,” a boy allegedly named Abu Anas al-Ansari, who was killed before he turned 15. Posts on two ISIS forums on Monday showed what the terror group said was the dead body of the boy, described as a “warrior of the 23 mm cannon” and a star “cub of the Caliphate.” Al-Ansari pledged allegiance to al-Qaeda’s branch in Syria, the Nusra Front, at the ripe age of 12 before joining ISIS in 2014, the Islamic State said its online posts, which were discovered by Vocativ’s deep web analysts. The boy allegedly operated an anti-aircraft cannon in Syria. “His age didn’t surpass 14,” one post said, adding: “may Allah accept him.”
