The National Investigation Agency's (NIA) chargesheet in the 2025 Red Fort blast case alleges that the accused followed the 'Lone Mujahid Pocket Book/How to Become an Assassin', an AQAP-linked manual detailing explosives and covert operations. The chargesheet identifies Umer Un Nabi, who died in the explosion, as the alleged mastermind and 'operational in-charge' of a revived Ansar Ghazwat-ul-Hind (AGuH) module.
