36 killed in 'Mother Of All Bombs' blast in Afghanistan

U.S. President Donald Trump's assessment of a blast by the so-called 'Mother of all bombs' in eastern Afghanistan on Thursday. A 22-thousand pound GBU-43 - like the one shown in the US army video - packing 11 tonnes of explosives and taking aim at caves and tunnels used by IS militants. It's the the largest non-nuclear bomb the U.S. has ever unleashed in combat.
