Singapore has taken action against two citizens for extremist activities linked to the ongoing Israeli-Palestinian conflict, bringing to eight the number of individuals dealt with under the Internal Security Act whose radicalisation stems from the Gaza crisis. The Internal Security Department announced the cases on Wednesday, revealing a troubling pattern of online radicalisation among young Singaporeans exposed to a complex web of violent extremist narratives.
Cyrus Dzulqarnain Al-Shahriar, a 19-year-old student, received a restriction order after authorities uncovered his involvement with an online Islamist extremist group. The case came to light when members of the public reported his anti-Semitic and pro-Hamas social media activity to authorities. More strikingly, he had taken photographs in the Marina Bay Sands area featuring materials from the extremist group, which he subsequently shared publicly on social media in November, effectively announcing his membership and allegiance to the organisation.
Tarmizi Mohd Taha, aged 30, received a detention order under the ISA following his admission that he would be willing to carry out violent attacks in Singapore if instructed by Hamas. His case presents a particularly concerning scenario, as Tarmizi, who works as a customer service officer, had previously served as a logistics assistant during his national service with the Singapore Police Force. He explicitly expressed a desire to leverage these skills to support Hamas operations, viewing such actions as a pathway to martyrdom and religious fulfilment.
While the two cases are unrelated and involve distinct pathways to extremism, both individuals share a common trigger: the escalation of Israeli-Palestinian violence following Hamas's October 7, 2023 attacks against Israel. This pattern is significant for regional security analysts, as it demonstrates how distant geopolitical conflicts can rapidly mobilise young people in Southeast Asia, bypassing traditional geographic boundaries through digital networks and online communities.
Cyrus's journey into extremism began innocuously in 2022 when he joined online religious study groups to deepen his Islamic knowledge. However, his exposure progressively shifted toward more radical content, including anti-Western narratives and material opposing the LGBTQ community. Following the October 2023 Hamas attacks, his worldview evolved further as he encountered pro-Hamas content online, eventually coming to view the killing of Israeli civilians as a legitimate form of religious struggle. By 2024, he had seriously contemplated travelling to Gaza to join Hamas operations, abandoning the plan only due to practical constraints and personal fear rather than ideological reconsideration.
The turning point in Cyrus's radicalisation came in early 2025 when he discovered and joined an online group advocating what authorities term Composite Violent Extremism, colloquially known as a "salad bar" of ideologies. This phenomenon, increasingly recognised as a security threat, involves individuals synthesising multiple and sometimes contradictory extremist belief systems into a personalised worldview that justifies violence. The group Cyrus joined espoused violent accelerationist thinking, believing that generating chaos through violence could dismantle what they characterised as a global order dominated by Western powers and Zionist interests, ultimately creating space for Islamic civilisation to flourish globally.
Having joined the group's private chat platform, Cyrus began openly glorifying historical terrorist attacks, including al-Qaeda's September 11 operations and the 2002 Bali Bombings, framing these acts as expressions of religious warfare. He engaged in what the group termed "digital jihad," participating in coordinated online harassment campaigns against users perceived as anti-Islam, manufacturing fake news to defame targets, and explicitly inciting violence against them. His online conduct progressively escalated to include public glorification of Hamas and Syrian militant organisations such as Hay'at Tahrir al-Sham.
A particularly disturbing development in Cyrus's case emerged when he encountered online material related to Elliot Rodger, the 2014 mass shooter who killed six people near the University of California, Santa Barbara. Rodger's incel ideology—derived from "involuntary celibate," referring to individuals, predominantly men, who blame society and women for their romantic and sexual rejection—resonated with Cyrus. He subsequently adopted incel identity markers, posting threats of murder and rape against women while using dehumanising terminology common to incel forums. His violent fantasies extended to targeting specific groups within school settings, particularly LGBTQ individuals and students in relationships.
The security authorities have noted that Cyrus never translated these violent thoughts into concrete preparatory action, nor did he share his extremist ideology with family members or schoolmates. Nonetheless, the combination of his public pledges to extremist groups, documented incitement of violence online, and articulated intentions toward multiple categories of potential victims constituted sufficient grounds for his restriction order. He will now undergo a structured rehabilitation programme designed to address and dismantle his radical ideological framework and violent cognitive patterns.
Tarmizi's case, while less elaborate in terms of ideological complexity, presents more immediate operational concerns. His explicit willingness to execute attacks on Singapore at Hamas's behest, combined with his intimate knowledge of law enforcement logistics from police national service, represented what authorities assessed as an active security risk requiring detention rather than merely restriction. His instrumentalisation of professional military skills for extremist purposes represents a recurring vulnerability pattern within Southeast Asian security services.
The emergence of Composite Violent Extremism, evident in Cyrus's case, signals an evolution in how young people construct extremist worldviews. Rather than adhering to traditional, ideologically coherent frameworks, individuals like Cyrus draw eclectically from Islamist narratives, anti-Western conspiracy theories, accelerationist violence philosophy, and incel resentment, creating hybrid belief systems that resist conventional counter-messaging approaches. This heterodox extremism complicates both identification and deradicalisation efforts, as no single narrative thread unites adherents.
For Malaysia and the broader Southeast Asian region, these Singapore cases carry immediate relevance. The digital platforms facilitating Cyrus's radicalisation operate across borders, and the ideological virality of Gaza-related narratives demonstrates how regional geopolitical events can rapidly cascade into security concerns in neighbouring countries. The speed of Cyrus's progression from Islamic religious study to violent extremist commitment—essentially compressed into years rather than decades—suggests that digital-era radicalisation operates at unprecedented velocity. Intelligence and security agencies across Southeast Asia must grapple with the reality that online extremist spaces now constitute primary recruitment and indoctrination venues, often preceding any physical-world organising.
The Singapore authorities have framed these eight cases linked to Gaza-related radicalisation as indicative of a broader domestic self-radicalisation threat, particularly among youth segments. The existence of multiple, interconnected online communities promoting violent extremism suggests that isolated individuals like Cyrus can rapidly integrate into transnational extremist networks without ever leaving their homes. This challenges traditional security models predicated on detecting physical movement, training camps, and organisational structures. Singapore's deployment of the ISA—a preventative detention mechanism—reflects the assessment that these individuals posed imminent risk despite lacking immediate operational capacity or concrete attack plans. The rehabilitation component of their orders represents an acknowledgment that addressing underlying ideological grievances and identity crises remains essential to long-term security outcomes.
