A radical teacher in the UK encouraged primary school children in an after-school class to write letters of support to ISIS. The notes, in childish writing, are decorated with handprints and drawings. They are addressed to ISIS fighters by names, and brand them as “heroes” and “diamonds among stones”.

The letters were posted on Twitter by @irhabiyya_18, meaning “terrorist_18″ and picked up by US think tank The Middle East Media Research Institute. Haras Rafiq, head of the counter-extremism Quilliam Foundation said: “She is clearly brainwashing youngsters. These kids are vulnerable.”

It is unknown if parents of the kids being radicalized share the teacher’s views.
