(File Photo)A month after the Red Fort blast, Union Home Minister Amit Shah on Friday said the explosion in Delhi happened with 40 kilograms of explosives, while three tonnes of explosives were recovered before they could detonate. Shah inaugurated the two-day ‘Anti-Terrorism Conference-2025’ here, organized by the National Investigation Agency (NIA), emphasizing a zero-tolerance approach to terrorism.He lauded Jammu and Kashmir Police probe into the Delhi explosion, where 40 kg of explosives detonated, but three tonnes were seized before they could detonate, and the entire team involved in conspiring this plot was apprehended before the Delhi blast could take place.“The investigation of this entire network was carried out very effectively by all our agencies. The investigations into the Pahalgam and Delhi blast cases are not examples of routine policing, but outstanding instances of watertight investigation. This also serves as a very significant example of how a constantly vigilant officer can save the country from such a massive crisis,” Shah said.So far, nine persons, associated with Dr Umar-un-Nabi, who drove the car that exploded near Red Fort in Delhi on November 10, which claimed 15 lives and left several others injured, have been arrested by the NIA.Highlighting recent successes, Shah also praised the response to the Baisaran Valley attack, which aimed to shatter Kashmir’s budding tourism and communal harmony. “Through this attack, the terrorists wanted to disrupt communal harmony in the country and deliver a blow to the new era of development and tourism that has begun in Kashmir. Based on extremely precise intelligence, our forces neutralized all three terrorists, delivering a stern message to Pakistan,” he said.“This is the first terrorist incident in which those who planned the terrorist act were punished by us through Operation Sindoor, and those who carried out the act with the weapons provided to them were neutralized through Operation Mahadev. At both ends, the Centre, the Indian security forces, and the people of India have given a strong and befitting reply to Pakistan’s terrorist masters through our security forces and intelligence agencies,” he added.Shah said, “Our team has conducted a complete and successful investigation of the Pahalgam terrorist attack, which agencies around the world will study in the coming days. The results of the investigation into the Pahalgam terrorist attack will put Pakistan in the dock on international platforms.”Story continues below this adShah has asked all the DGs to must move forward with “Trial-in-Absentia” without fear of the controversies associated with it. “This will force fugitives to return to the country. All Central agencies, together with the state police, should form a ‘Team India’ that works effectively for national security,” he added.The event, saw the launch of three major initiatives: an updated NIA crime manual, the Organised Crime Network Database, and the Lost/Looted and Recovered Weapon Database. “This platform analyses terrorist incidents from the past year globally and enhances our capabilities against evolving threats, especially technology-driven ones,” he said, urging proactive measures against invisible future challenges.“Today, a database on organized crime networks has also been released. The organized crime networks initially operate for the purpose of ransom and extortion, but when their leaders flee abroad and settle there, they automatically come into contact with terrorist organizations and then use the proceeds from ransom and extortion to spread terrorism within the country. Every state must, under the guidance of the NIA and CBI, with the cooperation of the IB, and by utilizing this database, eliminate it within their jurisdiction,” he said.As India rises as the world’s fourth-largest economy with strategic Indian Ocean positioning, Shah warned of proportional security challenges. “Secure borders start miles inward; we need multi-layer grids against cyber warfare, economic misuse, and hybrid terrorism,” he said, announcing a forthcoming 360-degree assault on organized crime networks that morph into terror financing via extortion rackets abroad.Mahender Singh Manral is an Assistant Editor with the national bureau of The Indian Express.
