The U.S. on Thursday dropped the most powerful conventional bomb in its arsenal on Nangarhar, Afghanistan.
The bomb, known in military ranks as “MOAB,” or the “mother of all bombs,” was used Thursday for the first time in combat, though it was developed in the early 2000s.
U.S. Army Gen. John Nicholson, commander of U.S. forces in Afghanistan, ordered the bomb dropped, according to reports. The target was believed to be ISIS tunnels and personnel in the Achin district of Nangarhar.
"This is the right munition to reduce these obstacles and maintain the momentum of our offensive against ISIS-K," he added, using the U.S. military's acronym for the IS affiliate.
