Investigators into the car explosion near Delhi’s Red Fort have sent more than 40 samples for forensic analysis, including remnants of two different explosives. Preliminary tests suggest that one of the devices contained Ammonium Nitrate (a fertiliser-turned-explosive) and the second appears to be more powerful, possibly involving RDX or PETN.
Ammonium nitrate alone is relatively stable, but when mixed with fuel oil (forming ANFO) and triggered by a detonator it can generate a supersonic blast. RDX and PETN are military-grade explosives capable of high-velocity detonations and more compact destructive force.
Investigators are also examining detonator circuits and electronic triggers used in the device, suggesting advanced planning and technical sophistication. The scale of destruction and blast pattern has raised concerns about both the source of explosives and the regulatory oversight of substances used for such attacks.
Probing agencies say final confirmation of the exact chemical composition, amount used and trigger mechanism will come once lab tests conclude.
