Özgür Altun, a Turkish national and leading propagandist for IS–KP, was arrested in Pakistan after years of orchestrating the group’s online media, recruitment, and logistics networks. His detention marks a major setback for IS–KP’s transnational communications and recruitment efforts across Turkey, Central Asia, and Europe. Altun’s evolution from a radical activist in Istanbul to IS–KP’s digital strategist illustrates the movement’s ability to draw on educated foreign operatives to globalize its reach.
