Shadow wars: the Taliban’s campaign against the Islamic State Khorasan Province

This paper examines the evolution of the Islamic State Khorasan Province (ISKP) from 2021 through 2024, tracing its transformation from a severely weakened entity to an adaptive, decentralised organisation capable of posing a persistent threat in Afghanistan.

Drawing on over 100 qualitative interviews with ex-ISKP members, supporters and sympathisers, it provides an insider perspective into ISKP’s strategies, challenges and resilience in the face of sustained Taliban counteroperations.

Despite significant losses – including the elimination of key leaders, mass surrenders and the disruption of critical operations – ISKP has maintained visibility and relevance. At the same time, Taliban counterterrorism strategies have evolved. The Taliban’s campaign has suppressed ISKP’s territorial and operational ambitions but has not eradicated its ideological appeal.
