Singapore has taken security action against two nationals whose radicalisation was triggered by the escalating Israeli-Palestinian conflict, bringing to eight the number of citizens dealt with under the Internal Security Act since the Hamas attacks on Israel in October 2023. The Internal Security Department issued a restriction order against Cyrus Dzulqarnain Al-Shahriar, a 19-year-old student, and a detention order against Tarmizi Mohd Taha, a 30-year-old customer service officer, following investigations into their extremist activities and expressed support for militant organisations.
Cyrus's case illustrates the evolving nature of home-grown extremism in Southeast Asia, where young people are increasingly exposed to fragmented online ideologies rather than cohesive terrorist doctrines. The student initially joined religious discussion groups in 2022 to deepen his Islamic knowledge, a common pathway for faith exploration among youth. Yet the online ecosystem exposed him to hardline content attacking Western values and LGBTQ communities, content he actively amplified through his own social media accounts. By 2023, following the October 7 attacks, he encountered pro-Hamas narratives that reframed civilian casualties as legitimate acts of religious warfare—a narrative that resonated with his evolving worldview.
What distinguishes Cyrus's trajectory is his adoption of what Singapore's security apparatus terms "composite violent extremism" or a "salad bar" of ideologies. Rather than adhering to a single terrorist group's ideology, he synthesised elements from multiple sources: Islamist accelerationism, incel misogyny, and anti-Zionist conspiracy theories. Early in 2025, he discovered online accelerationist circles that promoted creating societal chaos through violence to establish an Islamic-dominated global order. These groups viewed Western nations, including Singapore, as extensions of American hegemony controlled by Zionist interests. Concurrently, he became fascinated by incel culture after encountering posts about Elliot Rodger, the 2014 mass shooter near the University of California, Santa Barbara, whose killing spree stemmed from sexual rejection and perceived social exclusion. Cyrus adopted incel terminology and produced violent fantasies against women and LGBTQ individuals, though authorities confirmed he did not take concrete preparatory steps.
The student's public pledge of allegiance to the extremist online group in November 2025 revealed his commitment to the cause. Tasked with photographing an extremist e-publication against the backdrop of Marina Bay Sands, he fulfilled the assignment and posted the images on social media, effectively announcing his membership. He then engaged in what the group termed "digital jihad," creating and spreading misinformation to defame individuals perceived as anti-Islam, inciting violence against them online, and glorifying terrorist attacks including Al-Qaeda's September 11 assault and the 2002 Bali Bombings. The lack of a coherent ideological framework did not diminish the security threat posed by his activities; rather, it underscores a troubling trend where young radicals construct personalised violent worldviews by cherry-picking from competing extremist narratives.
Tarmizi's case, by contrast, reflects a more direct pathway to operational extremism. The 30-year-old customer service officer, who served in the Singapore Police Force as a logistics assistant, explicitly stated his willingness to execute attacks on Singapore if Hamas directed him to do so. His security clearance and access to police infrastructure would have made him potentially valuable to hostile entities, though his case appears to have been intercepted before any planning reached an advanced stage. Tarmizi believed that assisting Hamas through his logistical expertise would constitute a legitimate contribution to the broader Islamic cause and bring him closer to achieving martyrdom, a theological justification common among operationally-minded militants across the region.
The concentration of eight ISA cases linked to the Gaza conflict within roughly eighteen months suggests that geopolitical events with strong religious or ideological dimensions can trigger waves of domestic radicalisation, even in stable societies with active deradicalisation programmes. The conflict has become a focal point for extremist recruitment narratives across Southeast Asia, particularly in online spaces where impressionable youth encounter competing ideologies without sufficient counternarratives or community intervention. Singapore's experience is relevant for Malaysia, which also faces periodic surges in extremist recruitment coinciding with conflicts in Muslim-majority regions.
The emergence of composite violent extremism as a security category reflects the fragmented nature of contemporary online radicalisation. Rather than teenagers joining established terror networks with clear hierarchies and doctrines, they construct hybrid belief systems from fragments encountered across encrypted forums, social media, and specialist websites. This approach complicates both prevention and deradicalisation efforts, as interventions designed for traditional ideological coherence may prove ineffective against individuals whose extremism lacks a coherent centre. Singapore's security authorities have recognised that the absence of a unified worldview does not reduce the threat level; instead, it means that individuals may rapidly shift tactics or targets based on online exposure, making predictive security work more challenging.
Both individuals are being subjected to rehabilitation regimes designed to address their radical beliefs. In Cyrus's case, the authorities have emphasised that while his violent ideations remained in the realm of fantasy rather than preparation, his public support for terrorist organisations and his documented incitement of violence online constitute genuine security risks warranting intervention. The restriction order framework allows the state to monitor his activities and constrain his access to extremist networks whilst providing programmatic support to reorient his thinking. For Tarmizi, the detention order reflects the higher assessed threat level posed by his explicit operational willingness, though the duration and conditions of his detention remain undisclosed.
The cases underscore a critical challenge facing Singapore and the broader Southeast Asian region: the digitalisation of extremist recruitment makes prevention increasingly difficult even in societies with sophisticated intelligence capabilities. Young people encounter radicalising content algorithmically, through peer referrals in encrypted chat groups, or via the documented pathway of exploring one ideology and being algorithmically nudged toward more extreme variations. The intersection of religious identity exploration, adolescent identity formation, and online algorithmic amplification creates conditions where even well-intentioned youth seeking to understand their faith can be steered toward violent ideological extremes.
For Malaysian policymakers and security agencies, the Singaporean cases offer several instructive lessons. First, the composite violent extremism phenomenon is not geographically isolated and likely affects Malaysian youth exposed to the same online ecosystems. Second, the timeframe from initial radicalisation to operational capability or public pledging of extremist allegiance can compress significantly in the digital age—Cyrus moved from religious exploration in 2022 to extremist pledge within three years. Third, the intersection of multiple marginalising factors (sexual isolation, perceived religious discrimination, geopolitical grievances) creates particularly volatile combinations, suggesting that community-level prevention efforts should address isolation and belonging rather than ideology alone. Finally, rehabilitation and deradicalisation programmes must account for the hybrid, personalised nature of contemporary extremism rather than assuming individuals hold coherent, predictable belief systems.
The broader regional security picture reflects how conflicts in distant theatres can catalyse domestic violence when amplified through digital networks and interpreted through competing extremist lenses. As the Gaza conflict continues to generate polarisation globally, Southeast Asian governments face the ongoing task of identifying and intervening with radicalised youth before they transition from online activity to physical planning. The challenge is particularly acute in plural societies where religious grievances intersect with other forms of alienation and where online communities can provide belonging and ideological coherence that may be lacking offline.
