London-based Quilliam Foundation, a counter-extremism thinktank co-founded by Maajid Nawaz, has launched a YouTube video targeting those who may be seeking out online call-to-arms messages from Isis and could be vulnerable to radicalisation. The latest video ad, developed by London agency Verbalisation, forms part of the Quilliam Foundation’s #notanotherbrother campaign which aims to provide a counter-narrative describing the human cost of radicalisation and exposure to Islamist extremism.
