The National Investigation Agency (NIA) has filed a 7,500-page charge sheet regarding the 2025 Red Fort blast in New Delhi, which resulted in 11 deaths and numerous injuries. The investigation uncovered that the explosive used was Triacetone Triperoxide (TATP), a substance previously utilized in various terrorist attacks globally. The charge sheet identifies 10 accused, including the main perpetrator, Dr. Umer Un Nabi, who died during the incident. These individuals were associated with Ansar Ghazwat-ul-Hind (AGuH), a faction of Al-Qaeda in the Indian Subcontinent, which was designated a terrorist organization in June 2018. The accused had reformed AGuH as 'AGuH Interim' after a failed migration attempt to Afghanistan and were involved in 'Operation Heavenly Hind', a plot aimed at overthrowing the Indian government and establishing Sharia rule. The NIA's investigation revealed that the group engaged in recruiting members, propagating extremist ideologies, and manufacturing explosives using commercially available chemicals. They also experimented with various types of improvised explosive devices (IEDs) to target security forces in Jammu and Kashmir and other regions of India.
