Islamic State – Khorasan Province

The Islamic State – Khorasan Province (ISIS–K, IS–K, IS–KP) is a regional branch of the Salafi jihadist group Islamic State (IS) active in South-Central Asia, primarily Afghanistan and Pakistan. ISIS–K seeks to destabilize and replace current governments within historic Khorasan region with the goal of establishing a caliphate across South and Central Asia, governed under a strict interpretation of Islamic sharia law, which they plan to expand beyond the region.

ISIS–K is responsible for numerous of attacks targeting civilians in Afghanistan and Pakistan, predominately against Shia Muslims, politicians, and government employees. In August 2017, ISIS–K and the Taliban jointly attacked several villages inhabited by the Shia Hazara minority in northern Afghanistan, resulting in the mass murder of Hazara men, women, and children within Sar-e Pol Province. Some of its most notable attacks include the 2021 Kabul airport attack that killed 13 American military personnel and at least 169 Afghans in Kabul during the U.S. withdrawal from the country, twin suicide bombings in July 2018 that killed at least 131 at election rallies in Pakistan, twin bombings in July 2016 that killed 97 Shia Hazara protestors in downtown Kabul, and a suicide bombing in July 2023 that killed 63 in Khar, Pakistan of a JUI (F) rally.

While the majority of ISIS–K attacks occur in eastern Afghanistan and Pakistan's Khyber Pakhtunkhwa Province, since April 2022, ISIS–K has expanded to conduct external operations beyond its traditional area of operations. In April and May 2022, respectively, ISIS–K launched rockets from Afghan territory into the country's northern neighbors of Uzbekistan and Tajikistan. In January 2024, two ISIS–K attackers carried out twin suicide bombings in Kerman, Iran, during a procession mourning the US assassination of Quds Force leader Qasem Soleimani, killing 94. In March 2024, four Tajik ISIS–K gunmen launched an attack on a concert hall in Krasnogorsk, Russia, with rifles and incendiaries, killing 144 and marking the group's first attack beyond Afghanistan's neighbors.

ISIS–K began with the dispatch of Afghan and Pakistani militants from al-Qaeda-aligned groups to the Syrian civil war, who returned to the region with instructions and funding to recruit fighters for a branch of the Islamic State in the Khorasan region. The group's traditional base of power began and remains in eastern Afghanistan along the border with Pakistan, recruiting from former dissatisfied fighters and dissenters of the Taliban as well as individuals from South and South East Asia.
