Key Islamic State Affiliate Appears to Back New Leader Jeff Seldin The reign of new Islamic State leader Abu Ibrahim al-Hashimi al-Qurashi is getting a boost, thanks to the apparent endorsement of one of the terror group's more influential affiliates. IS media officials Tuesday released photos of fighters with IS-Khorasan, the affiliate in Afghanistan, giving bay'ah (oath of allegiance) to Qurashi.

"Their message seems to be that it's business as usual and that nothing has changed except for their leader," said Raphael Gluck, co-founder of Jihadoscope, another company that monitors online activity by Islamist extremists. "They want to show they can mobilize and fast, and that the caliphate is still there," he said. Afghanistan affiliate IS-Khorasan has been of the most resilient of the IS affiliates, surviving repeated attempts by U.S. and Afghan forces to annihilate its leadership and fighters. At one point, in April 2017, the United States dropped the largest non-nuclear bomb in its arsenal -- a GBU-43 Massive Ordnance Air Blast -- on an IS cave and tunnel system in Afghanistan's Nangarhar province to little avail. But rather than shrink, U.S. officials say IS-Khorasan gained ground, now boasting as many as 5,000 fighters across the country.
