Adam Hadley, the executive director of Tech against Terrorism, a UN-founded anti-extremism group, said: “We are alarmed that a designated terrorist organisation operates with such impunity online. So far the international community has targeted the Houthis through mainly military means. But this revelation demonstrates that terrorists must be countered online, not just through bombs and bullets.
“The Houthis have long relied on the internet as their most important strategic communications tool and now, it seems likely, as a dual-use marketplace to trade arms. Tech companies must comply with sanctions, swiftly remove content linked to the group and protect users from terrorism and extremism.”
