The U.S. has struck back strike against an ISIS-K planner, about 48 hours after a deadly suicide attack killed 13 Americans and about 170 Afghans, U.S. Central Command (CENTCOM) said in a statement Friday.

CENTCOM said the drone strike targeted an Islamic State member in Nangahar believed to be involved in planning the attacks against the U.S. in Kabul. 

“U.S. military forces conducted an over-the-horizon counterterrorism operation today against an ISIS-K planner. The unmanned airstrike occurred in the Nangarhar Province of Afghanistan,” spokesman Capt. Bill Urban said.

“Initial indications are that we killed the target. We know of no civilian casualties,” Urban continued.
