Nazmul Hasan Mamun: Quiet Bomb-Maker’s Rise Inside Islamic State Bengal
Executive Summary:
- A skilled bomb-maker and key Islamic State in Bengal (ISB) operative, Nazmul Hasan Mamun provides the technical expertise and low-visibility profile needed for the militant group to survive sustained counterterrorism pressure.
- Mamun was arrested in 2017 for building explosives for a thwarted attack, but he used his time in prison to build extremist networks before a controversial 2024 acquittal allowed him to resume his militant activities.
- Mamun’s trajectory exposes vulnerabilities in Bangladesh's counterterrorism framework, underscoring the urgent need to address weak inter-agency coordination, the intelligence-evidence gap, and prison networking.
