ISI Unit ‘S1’ Identified as Key Driver of Cross-Border Terrorism into India
New Delhi: A clandestine unit within Pakistan’s Inter-Services Intelligence (ISI), known as S1, has been identified as a central orchestrator of cross-border terrorism into India, sources have revealed to NDTV. The unit, whose name stands for “Subversion 1,” is allegedly responsible for a string of devastating attacks, from the 1993 Mumbai blasts to the recent terror attack targeting tourists in Pahalgam, Jammu and Kashmir.
According to intelligence sources, S1 is the “biggest driver behind the forces of cross-border terrorism in Pakistan.” The unit is headed by a Colonel in the Pakistani Army, with two ranking officers, codenamed “Gazi 1” and “Gazi 2,” overseeing active operations.
Headquartered in Islamabad, S1 allegedly funds its operations primarily through drug money. The unit’s personnel and trainers are experts in bomb-making, improvised explosive devices, and small arms handling. Sources indicate that S1 possesses detailed maps of numerous locations within India.
While the unit has reportedly been active for the past 25 years, Indian security agencies have only recently pieced together the full scope of its activities. S1 is specifically tasked with carrying out terror attacks within India and maintains connections with various terrorist groups operating in Pakistan, including Jaish-e-Mohammed, Lashkar-e-Taiba, and Hizbul Mujahideen.
“S1 personnel have been seen in terror training camps of groups… They try to blend in by keeping long beards and wearing local, ethnic clothes,” a source stated. The unit’s operations are so secretive that many trainees are unaware of their instructors’ affiliation with S1. Over the past two decades, S1 is believed to have trained thousands of terrorists.
The revelations about S1 are likely to further strain relations between India and Pakistan and raise questions about Pakistan’s commitment to combating terrorism.
