Explainer: How dangerous is Afghanistan's Islamic State
The HinduThe Islamic State offshoot that Americans blame for Thursday's deadly suicide attacks outside the Kabul airport coalesced in eastern Afghanistan six years ago, and rapidly grew into one of the more dangerous terror threats globally. Despite years of military targeting by the U.S.-led coalition, the group known as Islamic State Khorasan has survived to press more assaults as the United States and other NATO partners withdraw from Afghanistan, and as the Taliban return to power. While intelligence officials believe al-Qaida fighters are integrated among the Taliban, the Taliban, by contrast, have waged major, coordinated offensives against the Islamic State group in Afghanistan. Taliban insurgents at times joined with both the U.S. and U.S.-backed Afghan government forces to rout the Islamic State from parts of Afghanistan's northeast.
