The GBU-43/B Massive Ordnance Air Blast Bomb (MOAB), nicknamed the "mother of all bombs,” was dropped at 7:32 p.m. local time Thursday, CNN reported.
The initial toll given by Afghan officials for Thursday's strike was 36. A statement released Friday through ISIS' media wing, Amaq News Agency, said none of the terror group's fighters were killed or injured.
The strike targeted a network of underground tunnels that ISIS had been using to stage attacks in Nangarhar province in eastern Afghanistan.
The bomb destroyed three underground tunnels, weapons and ammunition, but no civilians were hurt, CNN reported, citing U.S. and Afghan officials.
