Dubai: International efforts to counter transnational terrorism are entering a new phase, with authorities shifting their focus from individual operatives to the leadership, financial, and organizational networks that sustain terrorist groups across borders.
A recent example is the U.S. Treasury Department’s July 23 sanctions against Mahmoud al-Abyari, a senior Egyptian Muslim Brotherhood leader based in the United Kingdom. The Treasury designated al-Abyari along with three individuals and three entities, alleging they provided material support to Hamas through an extensive financial and logistical network.
According to U.S. authorities, the network relied on Muslim Brotherhood-linked affiliates, charitable organizations, and underground banking channels to raise, transfer, and conceal funds across multiple jurisdictions. Officials described the system as a sophisticated, multi-layered structure designed to facilitate financial flows while avoiding detection.
Al-Abyari, identified by the Treasury as the secretary-general of the Muslim Brotherhood, was accused of helping raise funds for two organizations that had already been sanctioned over alleged links to Hamas. Authorities also identified two charities and a Türkiye-based company that allegedly transferred hundreds of thousands of dollars to Hamas while offering underground banking services involving both traditional currencies and cryptocurrency.
Analysts say the significance of these sanctions lies less in the designation of one individual than in what they reveal about the interconnected nature of modern terrorist financing. The Treasury argues that leadership figures, fundraising organizations, and financial intermediaries increasingly operate as parts of a coordinated international network.
Commenting on the sanctions, U.S. Treasury Secretary Scott Bessent said the administration would continue targeting those who enable Hamas through charities, businesses, or clandestine financial networks.
The move reflects broader changes in the financing methods used by transnational extremist organizations. The Financial Action Task Force (FATF), in its 2025 assessment, found that terrorist financing has become increasingly decentralized, with networks relying on regional financial hubs, informal money transfer systems, self-financing, and traditional fundraising methods.
Experts note that these developments mean there is often no single headquarters or command center that can be dismantled. Instead, leadership may be spread across several countries, with charities, financial facilitators, and trusted intermediaries working together to maintain the network.
Jennifer Shasky Calvery, former director of the U.S. Financial Crimes Enforcement Network (FinCEN), has previously described financial intelligence as a tool that helps authorities “connect the dots” between seemingly unrelated individuals and organizations. Such analysis, she said, has played a crucial role in identifying terrorist supporters and overseas financial networks.
Observers also suggest that governments are increasingly treating extremist organizations as integrated global networks rather than isolated regional branches. This approach places greater emphasis on identifying the links between leadership, financing, and operational structures.
Former U.S. Treasury official Alex Zerden described financial sanctions as a “tool of first resort” in counterterrorism efforts. However, he also warned that the growing complexity of international financial networks has placed unprecedented analytical demands on U.S. financial intelligence agencies.
Beyond disrupting terrorist financing, these measures also have wider diplomatic implications. Countries hosting individuals or organizations linked to such networks may face increased pressure to strengthen financial oversight, enhance information sharing, and review their counterterrorism policies.
Kenya, for example, updated its counterterrorism financing and anti-money laundering legislation in 2025 by amending both the Prevention of Terrorism Act and the Proceeds of Crime and Anti-Money Laundering Act. The revised laws explicitly address financial activity conducted through both formal and informal channels.
Such national legal frameworks have become increasingly important to the effectiveness of international sanctions. While a designation issued by the United States can restrict access to the American financial system, its broader impact depends on regulators, banks, and intelligence agencies in other countries identifying similar financial relationships and taking coordinated action.
Authorities are therefore expanding their focus beyond simply adding names to sanctions lists. Increasing attention is being given to understanding how networks adapt by replacing sanctioned intermediaries, redirecting financial flows, or creating new organizational structures to maintain operations.
In this evolving strategy, the concept of a terrorist “control room” no longer refers to a single location. Instead, it represents a dispersed system of leadership, financing, and trusted relationships that enables transnational networks to survive even after individual members or organizations are sanctioned.
As governments continue refining their approach, the central challenge is identifying and disrupting these interconnected relationships before they can be re-established. The effectiveness of this strategy will largely depend on whether authorities can map and dismantle these networks faster than they are able to rebuild, with further sanctions against additional individuals and entities remaining a strong possibility in the months ahead.
