Washington: The Pentagon on Friday released video footage of the moment that the GBU-43 bomb, the largest non-nuclear bomb in the US arsenal, destroyed a complex of caves and tunnels of the Islamic State (IS) in Afghanistan.

The aerial images show the moment when the so-called "mother of all bombs", which had never been used until this Thursday, hit the side of a mountain in the Achin district of Nangarhar province with a explosive power equivalent to 11 tons of TNT, Efe news reported.
