As the investigation continues into the Delhi Red Fort blast, reports hint that the blast could have been triggered by Ammonium Nitrate Fuel Oil (ANFO), a powerful detonator. Initial probe reveals no trace of RDX, according to reports.
According to reports, initial forensic findings have revealed that ANFO and detonators were used to trigger the powerful explosion. If the presence of the ANFO is confirmed, this could also point fingers at the involvement of the Faridabad terror module. The Haryana and Jammu and Kashmir police seized 2,900kg of explosives from the terror module, which included Ammonium Nitrate.

Police believe that Dr Umar, the suspected suicide bomber, did not leave the vehicle so as to ensure that the ANFO stacked inside the vehicle is not discovered. CCTV footages show that the vehicle was parked near a mosque for three hours, and the driver did not alight from the vehicle. The explosion happened just after the vehicle left the parking lot.
Though Ammonium Nitrate is not exactly banned in India, its use, storage, and transport are heavily regulated under the Explosives Act, 1884, and the Ammonium Nitrate Rules, 2012. Any combination of ammonium nitrate exceeding 45 per cent by weight is considered an explosive, and licenses are required for its manufacture, sale, storage, and transport.
An odourless, white crystalline chemical, Ammonium Nitrate is widely used a a fertiliser and can be used as a catalyst under the right conditions to ignite a fire when mixed with fuel oil.
In the case of the Delhi blast, there are suspicions that the fuel oil was used to make it explosive, and it was detonated by an external source.
