Security agencies, including the Intelligence Bureau (IB), the National Investigation Agency (NIA), and state police forces, have flagged a disturbing shift in radicalisation tactics adopted by Islamic State (IS) and Al-Qaeda in South India — one that deliberately bypasses the youth themselves and instead targets their parents and close relatives. The strategy, now being described by officials as 'home-radicalisation', is being treated as one of the most difficult counter-terrorism challenges to detect and disrupt.

A New Playbook: Targeting the Family Unit

According to officials familiar with ongoing de-radicalisation efforts, IS and Al-Qaeda have recalibrated their approach after recognising that online surveillance of vulnerable youth — particularly college students, unemployed young people, and those who are disgruntled — has become extensive. Rather than directly approaching potential recruits online, handlers based abroad are now reportedly reaching out to parents and close relatives of these individuals.

'There is particular emphasis on college students, unemployed youth and those who are disgruntled. The Islamic State and Al-Qaeda have realised that online surveillance of these groups is extensive. Their current strategy is, therefore, to reach out directly to the parents or close relatives of potential recruits,' an official said.

Critically, the objective is not to convert the parents themselves to a violent ideology. Instead, the handlers work to draw family members into the network and persuade them to initiate radicalisation within their own households — a method officials say carries far less risk of detection, since parents and relatives attract the least suspicion from security agencies.

Why Home-Radicalisation Is Alarmingly Effective

Officials point to the inherent trust dynamic within families as the primary reason this method succeeds. 'A child very rarely questions the parent or a relative. He believes what they are saying is the gospel truth and would blindly follow what they are saying,' an official said, adding that this makes the radicalised youth 'extremely radical and highly dangerous.'

By contrast, third-party radicalisation — where a handler directly approaches a young person — reportedly has only a two-in-ten success rate, with many initial contacts losing motivation or backing out during the process. When a parent or close relative is involved, that rate climbs significantly, making family-mediated radicalisation a far more efficient tool for terror outfits.

Tamil Nadu, Kerala, Karnataka: The Primary Theatres

States such as Tamil Nadu, Kerala, and Karnataka have reportedly been the most active radicalisation zones for both IS and Al-Qaeda in recent years. Officials note that the groups have also shifted their immediate operational goals — rather than directing newly radicalised youth to carry out lone-actor attacks, handlers are now telling recruits to hold off on violence. The current strategy, according to officials, involves preaching extremist ideology discreetly, attempting to integrate into political systems, and building social legitimacy, while avoiding mass-casualty incidents for now.

Thiruvananthapuram Case: A Warning Sign

One documented instance of home-radicalisation has already come to light. In Thiruvananthapuram, the Venjaramoodu police invoked provisions of the Unlawful Activities (Prevention) Act (UAPA) after a 16-year-old boy was allegedly radicalised by his own mother and stepfather, who were reportedly persuading him to join the Islamic State. The case was registered in November 2025. Officials cautioned, however, that this discovery should not be read as a deterrent — terror groups are expected to attempt similar operations on a wider scale.

De-Radicalisation Efforts and the Road Ahead

Agency-led de-radicalisation programmes have had measured success in drawing youth back into the mainstream by exposing the gap between recruiter promises and reality. Officials acknowledge, however, that reversing home-radicalisation is a significantly harder task. 'To convince a person radicalised by their parent or radicalised against joining these terror outfits would be a Herculean task, as the process is taking place firsthand and not through some third-party handler,' an official said.

Security agencies are now recalibrating monitoring frameworks to account for family-unit radicalisation as a distinct threat vector, and de-radicalisation initiatives in the southern states are increasingly focused on identifying and counselling not just at-risk youth, but also the family environments around them.
