The world is witnessing a significant shift in the landscape of global terrorism, with a notable decline in overall fatalities but a worrying concentration of incidents in specific regions and a concerning rise in Western nations. The latest Global Terrorism Index 2026, compiled by the Institute for Economics & Peace (IEP), paints a complex picture of this evolving threat.
A Global Decline, But Not Uniformly
In 2025, the grim tally of lives lost to terrorist attacks worldwide fell by a substantial 28% compared to the previous year, reaching 5,582 fatalities. This downward trend is also reflected in the number of incidents, which decreased by 22% to 2,944. This continues a positive trajectory, as global deaths have significantly decreased since their peak of nearly 11,000 in 2015.
However, this decline is far from evenly distributed. A staggering 70% of all fatalities occurred in just five countries: Pakistan, Nigeria, and Burkina Faso are among those bearing the brunt. This stark statistic underscores a critical observation: terrorism is increasingly becoming a phenomenon confined to a smaller number of areas already grappling with conflict.
The Sahel: A Persistent Epicentre
The Sahel region in sub-Saharan Africa stands out as a persistent epicentre of this global challenge. It now accounts for the majority of terrorism-related deaths worldwide. The ongoing instability, coupled with weak governance and persistent cross-border militant activities, continues to fuel the flames of extremism in this vulnerable region.
A Divergent Trend: The West’s Rising Threat
In stark contrast to the global decline, Western countries are experiencing an alarming upward trend in terrorism-related deaths. The IEP report indicates a dramatic 280% increase in fatalities in 2025, with deaths rising to 57. While these absolute numbers may still be relatively low compared to historical peaks, the nature and drivers of these attacks are evolving.
The report links recent incidents in the West to a disturbing confluence of ideologies, including “anti-Semitism, Islamophobia, and political terrorism,” highlighting the growing influence of ideological violence.
The Rise of the “Lone Wolf” and Online Radicalisation
A key factor contributing to the rising threat in the West is the increasing prevalence of “lone wolf” attacks. The report reveals that these self-radicalised individuals were responsible for a staggering 93% of deadly terrorist attacks in Western countries over the past five years. This decentralised nature of the threat presents a significant challenge for authorities, making detection and prevention considerably more difficult.
Furthermore, a generational shift is evident in the radicalisation process. The report identifies the “radicalisation of young people” as one of the most pressing security concerns in the West. The digital age, with its pervasive online content, is accelerating this process, dramatically shortening the timelines for individuals to become radicalised and mobilised.
Global Hotspots and Future Outlook
The divergence in trends between different regions reflects a broader reshaping of global terrorism.
Pakistan’s Grim Reality: According to the report, Pakistan now ranks as the country most severely affected by terrorism. In 2025, it recorded 1,139 deaths and over 1,000 incidents. This surge is partly attributed to cross-border militancy linked to the ongoing developments in Afghanistan.
Sub-Saharan Africa’s Mixed Picture: While some countries in sub-Saharan Africa have seen a decline in terrorist activity, others, such as Nigeria and the Democratic Republic of the Congo, have experienced sharp increases. These rises are often linked to groups affiliated with the Islamic State.
Conflict as a Catalyst: The report unequivocally highlights the critical role of conflict as a primary driver of terrorism. Nearly all terrorism-related deaths occur in countries already embroiled in war or significant instability, underscoring how violence thrives and proliferates in fragile environments.
Looking ahead, the IEP warns that geopolitical tensions could lead to a resurgence in terrorist activity, potentially extending beyond traditional hotspots. Conflicts involving Iran and its regional allies are cited as potential catalysts for increased attacks.
The overarching trend is not one of terrorism disappearing, but rather of its redistribution and transformation. Terrorism is becoming more concentrated in specific areas, more fragmented in its execution, and, in many instances, significantly less predictable. This evolving dynamic demands a nuanced and adaptive approach to counter-terrorism strategies worldwide.
