For much of the period following the Taliban’s return to power in August 2021, European engagement with Afghanistan was shaped primarily by humanitarian assistance, migration management and limited diplomatic engagement. Counterterrorism remained part of the conversation, but it was no longer the defining lens through which Afghanistan was viewed. That strategic balance is beginning to shift.
Across European capitals, there is growing recognition that instability in Afghanistan cannot be treated solely as a regional issue. Terrorist organizations operating from Afghan territory have the potential to undermine regional stability, strengthen transnational extremist networks and generate security challenges that ultimately extend beyond South Asia. As a result, Afghanistan is increasingly being viewed not only as a humanitarian concern but also as a long-term strategic security issue for Europe.
This evolution reflects a broader realization that preventing terrorist sanctuaries is no longer simply a regional objective. It is increasingly becoming part of Europe’s own security agenda.
Europe Is Sending a Different Message
The clearest indication of Europe’s evolving approach comes from two recent interventions by senior European officials. Richard Lindsay, the United Kingdom’s Special Representative for Afghanistan, warned that Tehrik-i-Taliban Pakistan (TTP) continues to benefit from training camps, weapons, financial support and safe havens inside Afghanistan, arguing that the group’s continued access to sanctuary contributes directly to regional instability. He also acknowledged Pakistan’s right under international law to defend itself against clear terrorist threats while urging the Taliban to take decisive action against TTP.
Similarly, Gilles Bertrand, the European Union’s Special Envoy for Afghanistan, described TTP as a terrorist organization and stressed that the Taliban bears responsibility for preventing Afghan territory from being used against neighboring countries. He warned that terrorist safe havens, training facilities, logistical support networks and financing mechanisms continue to fuel regional instability, underscoring the importance of preventing Afghan territory from serving as a base for cross-border attacks.
Taken together, these statements represent more than routine diplomatic messaging. They signal a noticeable evolution in European policy thinking. For several years, European engagement with Afghanistan focused largely on humanitarian assistance, migration management and political dialogue. Today, senior European officials are increasingly framing Afghanistan as a counterterrorism challenge with direct implications for both regional and European security.
Their remarks also echo concerns that Pakistan has raised consistently and that have increasingly been reflected in successive United Nations Security Council Monitoring Team reports. By publicly highlighting terrorist sanctuaries, operational freedom and cross-border threats, European officials have moved beyond general security discussions to focus directly on the infrastructure that enables terrorist organizations to operate from Afghan territory.
International Assessments Reinforce the Concern
The concerns expressed by European officials closely align with successive United Nations Security Council Monitoring Team reports.
The 35th, 36th, 37th and Sixteenth Monitoring Team reports describe the continued presence of more than twenty terrorist organizations in Afghanistan, including TTP, Al-Qaeda, Islamic State Khorasan Province (ISKP), ETIM/TIP, the Islamic Movement of Uzbekistan and Jamaat Ansarullah. These assessments estimate that Afghanistan hosts between 13,000 and 23,000 terrorist fighters and continue to identify eastern Afghanistan as a principal operating area for approximately 6,000 to 6,500 TTP fighters and their family members.
For European policymakers, these findings carry broader strategic significance. Terrorist sanctuaries have historically demonstrated an ability to evolve from localized threats into wider international security challenges. Afghanistan’s own experience before 2001 illustrated how extremist organizations operating in permissive environments could develop regional networks that eventually acquired global reach. Preventing the re-emergence of such conditions is therefore not only a South Asian security objective but also an important European interest.
The growing European concern also reflects a wider international convergence. Russia has repeatedly warned that Afghanistan continues to host numerous terrorist organizations capable of destabilizing the broader region. China has consistently called for stronger action against TTP, ETIM/TIP, Al-Qaeda and ISKP. The United States has likewise criticized the Taliban for failing to implement its counterterrorism commitments and for allowing internationally designated terrorist groups to remain active inside Afghanistan.
Beyond the United Nations, similar concerns have been reflected in assessments by the Special Inspector General for Afghanistan Reconstruction (SIGAR), discussions within the Shanghai Cooperation Organisation (SCO), warnings issued through the Collective Security Treaty Organization (CSTO), and consultations under the Moscow Format. Although these institutions differ in their mandates and perspectives, they increasingly identify Afghanistan as a permissive environment for terrorist recruitment, facilitation, financing and cross-border operations.
The 2022 killing of Al-Qaeda leader Ayman al-Zawahiri in a safe house in Kabul further intensified international scrutiny. For many governments, the incident raised serious questions about Taliban assurances that Afghan territory would no longer provide sanctuary to internationally designated terrorist figures.
Taken together, these developments demonstrate that concerns about Afghanistan’s terrorist landscape are no longer confined to one country or one region. They are increasingly shared by neighboring states, major powers, European governments and international monitoring bodies.
Counterterrorism and Civilian Protection Must Advance Together
Recent cross-border violence between Afghanistan and Pakistan has highlighted another reality confronting the international community: legitimate security concerns and the protection of civilians must advance together.
Following Pakistan’s reported strikes in Paktya, Paktika and Kunar provinces, the United Nations Secretary-General expressed concern over civilian casualties, called for an immediate cessation of hostilities and urged both countries to resolve their differences through diplomacy. The United Nations Assistance Mission in Afghanistan (UNAMA) has stated that it continues to verify reports of civilian casualties while humanitarian organizations assess displacement and prepare emergency assistance.
These concerns deserve careful attention. International humanitarian law requires the protection of civilians and civilian infrastructure at all times, and allegations of civilian harm should be investigated independently, transparently and impartially.
At the same time, humanitarian concerns should not obscure the broader security environment repeatedly identified in international assessments. The continued presence of terrorist organizations operating from Afghan territory remains a significant challenge for neighboring countries and an issue of growing concern for the wider international community.
Protecting civilians and addressing terrorist infrastructure should therefore be viewed as complementary rather than competing objectives. Sustainable regional stability depends on progress in both areas.
Europe Must Balance Engagement with Accountability
Under the Doha Agreement, the Taliban committed to ensuring that Afghan territory would not be used against other countries and pledged to deny terrorist organizations sanctuary, recruitment opportunities, financing and operational support.
Nearly five years later, successive United Nations assessments, statements by European officials and reports from regional security forums continue to raise questions about the implementation of those commitments. Rather than diminishing, international concern regarding TTP, Al-Qaeda and other extremist organizations has continued to grow.
Humanitarian engagement with Afghanistan remains essential, particularly given the severe humanitarian needs facing the Afghan population. However, humanitarian assistance alone cannot substitute for effective counterterrorism. Meaningful international engagement with the Taliban will ultimately depend on credible and verifiable progress in preventing Afghan territory from being used by internationally designated terrorist organizations.
Europe’s growing recognition of Afghanistan’s terrorist sanctuary problem reflects a broader reality: instability in Afghanistan rarely remains confined to South Asia. Whether through terrorism, migration or transnational extremist networks, developments in Afghanistan have repeatedly demonstrated their capacity to affect European security.
A durable European strategy will therefore require balancing continued humanitarian engagement with sustained diplomatic pressure for verifiable counterterrorism commitments. Reducing the space available to terrorist organizations is essential not only for regional stability but also for strengthening international confidence and creating the conditions for any meaningful normalization of relations with the Taliban.
