Islamic State Khorasan (IS-K).

Book excerpt: Islamic State Khorasan (IS-K) is the Islamic State’s Central Asian province and remains active three years after its inception. The Islamic State announced its expansion to the Khorasan region in 2015, which historically encompasses parts of modern day Iran, Central Asia, Afghanistan, and Pakistan.1 Despite initial skepticism about the group’s existence from analysts and government officials alike, IS-K has been responsible for nearly 100 attacks against civilians in Afghanistan and Pakistan, as well as roughly 250 clashes with the U.S., Afghan, and Pakistani security forces since January 2017.2 Though IS-K has yet to conduct attacks against the U.S. homeland, the group represents an enduring threat to U.S. and allied interests in South and Central Asia. This backgrounder is an overview of the history, leadership, and current strategic goals of IS-K.
