The "mother of all bombs" killed 36 ISIS fighters, according to Afghan officials.
The U.S. military dropped the largest non-nuclear bomb in its arsenal — the GBU-43/B Massive Ordnance Air Blast — in Afghanistan on Thursday. Its target was an underground cave complex used by ISIS.
Here's how it works: The device actually explodes in the air. It forces so much pressure downward that structures — like underground tunnels — collapse. It was built and tested during the Iraq War in the early 2000s.
Thursday's bomb destroyed three ISIS tunnels in the underground network along with weapons and ammunition.
A spokesperson for the Afghan Ministry of Defense said no civilians were harmed in the attack.
