Who is ISIS-K, the group officials blame for the Kabul airport bombings?

A horrific terrorist attack at the Kabul airport on August 26 killed at least 12 US service members and more than 60 Afghans attempting to flee the country. US officials are attributing the attack to an ISIS affiliate.

The details of the attack at Hamid Karzai International Airport and a nearby hotel are still unfolding. But Gen. Kenneth McKenzie Jr. told reporters on the day of the attack that those responsible for the twin suicide bombings and subsequent barrage of gunfire were “assessed to have been ISIS fighters” and “ISIS gunmen.” Shortly thereafter, ISIS formally claimed responsibility for the attacks.

Earlier in the day, the Associated Press and other news agencies cited unnamed US government officials who said the attacks are believed to have been carried out by a violent group known as the Islamic State Khorasan, an Islamic State affiliate also known as “ISIS-K.”
