US forces in Afghanistan dropped the military's largest non-nuclear bomb on an Islamic State target in Afghanistan, according to the Pentagon.
A Pentagon spokesman said it was the first-ever combat use of the bomb, known as the GBU-43, which he said contains 11 tons of explosives.
Archive shows the bomb being tested at Eglin Air Force Base in Florida on 21 November 2003.
The Air Force calls the bomb the Massive Ordnance Air Blast bomb.
Based on the acronym, it has been nicknamed the "Mother Of All Bombs."
The Pentagon said the bomb was dropped on a cave complex believed to be used by ISIS fighters in the Achin district of Nangarhar province, very close to the border with Pakistan.
