Paper: GS – III, Subject: Internal Security, Topic: Challenges to Internal Security Through Communication networks, Issue: National IED policy.
Context:
The recent Red Fort blast, confirmed to be caused by a mixture of ammonium nitrate and triacetone triperoxide (TATP), underscores the persistent threat posed by IEDs in India.
Key Takeaways:
About Improvised Explosive Device:
- An IED is a type of unconventional explosive weapon that can take any form and be activated in a variety of ways.
- IEDs are used by criminals, vandals, terrorists, suicide bombers, and insurgents.
- Because they are improvised, IEDs can come in many forms, ranging from a small pipe bomb to a sophisticated device capable of causing massive damage and loss of life.
- The extent of damage caused by an IED depends on its size, construction, and placement and whether it incorporates a high explosive or propellant. Â
- The term IED came into common usage during the Iraq War that began in 2003.
Materials Used as Explosives in IEDs:
- Many commonly available materials, such as fertilizer, gunpowder, and hydrogen peroxide, are used as explosive materials in IEDs.
- Explosives must contain a fuel and an oxidizer, which provides the oxygen needed to sustain the reaction.Â
- A common example is ANFO, a mixture of ammonium nitrate, which acts as the oxidizer, and fuel oil (the fuel source).
Current Trends and Challenges:
Data from the National Bomb Data Centre of NSG indicates a declining trend in IED blasts across conflict zones and the hinterland. However, several concerning trends persist:
- Hybrid Explosives: Terrorist groups are increasingly using a mix of military-grade, commercial, and homemade explosives in IEDs.
- Cross-Border Smuggling: Military-grade explosives are often supplied by Pakistani handlers via drones or human couriers. Despite improved border management, the challenge remains in intercepting every consignment.
- Diversion of Commercial Explosives: Commercial explosives and detonators, used in mining and construction, are vulnerable to pilferage, especially in insurgency-prone areas.
- Homemade Explosives: While commonly used fertilizers in India have safeguards, precursor chemicals that can be used to extract explosives need stricter monitoring.
National Counter-IED Policy Framework:

The threat of IEDs in India is real and evolving. A comprehensive National Counter-IED Policy is essential to effectively address this menace. The policy should be dynamic and adaptable to address emerging threats and technological advancements in IED fabrication and deployment.
