THE United States has dropped a Massive Ordnance Air Blast Bomb – the largest non-nuclear weapon in its arsenal – on an ISIS tunnel target in Afghanistan.

The bomb was dropped in Afghanistan’s Nangarhar province, the Pentagon has confirmed.

The blast radius is believed to be over 300 meters and the weapon is described as “the father of all bombs”.

It is the very first time the weapon has been used in combat.

It comes as war fears reach fever pitch – with Kim Jong-un’s North Korea on the brink of sparking global conflict.

The bomb weighs approximately 21,000lbs.
