September 11, 2026 Peace and Security
A quarter of a century after the terrorist attacks of September 11, 2001, terrorism has become more fragmented and increasingly uses new technologies, while it is more difficult to detect lone attackers preparing attacks than to expose networks. This was stated by UN representatives at a Security Council meeting dedicated to the anniversary of the tragedy and the evolving terrorist threat.
Terrorist attacks that changed the course of history
As a result of the September 11, 2001 attacks, it should be recalled, nearly three thousand people died. Among the victims were citizens of 90 countries. Many were injured, and the consequences of the tragedy affected families and entire communities around the world. The meeting on Friday began with a moment of silence, during which the members of the Security Council paid tribute to those who died.
The unimaginable horror of that day caused all humanity to shudder
“The unimaginable horror of that day made all humanity shudder. In just minutes, it radically changed the course of history, making the world less safe for everyone,” said Eihab Omaish, Acting Head of the United Nations Counter-Terrorism Office, in his speech.
According to him, on the anniversary of the tragedy it is important to remember not only the victims but also those who survived. The stories of people who survived the terrorist attacks—stories of loss, fear, resilience, and hope—should remain at the center of international efforts to combat terrorism.
UN Security Council Resolutions
After the attacks, the Security Council adopted Resolution 1373, which obligated states to prevent terrorism, hold terrorists accountable, and deny them safe haven. Since then, the Council has adopted more than 20 additional counter-terrorism resolutions. These address, in particular, incitement and recruitment of individuals, violent extremism, the cross-border movement of terrorists, border strengthening, and the prevention of terrorism financing.
How threats have changed
However, over the past years the threat itself has also changed. As noted by Natalia German, head of the Executive Directorate of the UN Security Council Counter-Terrorism Committee, terrorist organizations are restructuring their structures, decentralizing operations, mastering new sources of financing, and exploiting instability, weakness of state institutions, resource conflicts, and public discontent.
At the same time, the role of decentralized cells, loosely connected networks, and lone-wolf terrorists is increasing. Their path to violence is often more difficult to detect and intercept. Terrorist and organized criminal groups also use maritime routes and critical infrastructure to transport people, weapons, and illicit goods.
Use of new technologies
The use of new technologies causes particular concern at the UN. The Internet serves terrorists not only for spreading propaganda and recruitment but also for gathering intelligence, planning attacks, and financing. Drones, which are used for surveillance, reconnaissance, and attacks, are becoming increasingly accessible, affordable, and effective.
“Recruitment and exploitation of children and youth is becoming one of the most pressing issues facing the counterterrorism community,” Herman warned. Extremists seek potential supporters in social networks, gaming communities, and other virtual spaces. The development of artificial intelligence and automatic content generation further increases the speed, scale, and precision of this activity.
Funding schemes
Financing schemes are also becoming more complex. Alongside cash and informal money transfer systems, terrorists use online payments, crowdfunding, mobile financial services, and virtual assets. They also generate income through extortion, kidnappings for ransom, illegal trafficking, and the exploitation of natural resources.
Forceful measures are not enough
UN representatives emphasized that force alone is not enough. It is necessary to eliminate the conditions exploited by terrorists, strengthen international cooperation, and engage local communities, civil society, women, youth, and those affected by terrorist attacks in preventive work.
At the same time, the fight against terrorism must be based on international law. “Measures that undermine the rule of law and human rights ultimately weaken our collective efforts,” Omaish said.
