Assam's Special Task Force (STF) has uncovered a sophisticated extremist network using digital platforms and encrypted communication for radicalization and recruitment. Investigations reveal transnational linkages, with groups like Jamaat-ul-Mujahideen Bangladesh and Imam Mahmuder Kafila employing methods such as 'Purvo Akash' for propaganda and recruitment. Recruits undergo a formal process involving oaths and verification by handlers in Bangladesh before induction, indicating a structured, cross-border extremist ecosystem.
