Pictures have emerged of the Islamic State of Iraq and the Levant (Isil) tunnel network in Afghanistan which the US targeted with "the Mother of All Bombs".

The US dropped the bomb - its largest explosive short of a nuclear weapon - on April 13 targeting what it said was a tunnel complex used by the jihadist group’s Afghan affiliate.

The GBU-43/B weighs 21,600lbs (9,797-kg) and was dropped from a cargo plane. It has the equivalent power of 11 tonnes of TNT explosives.
