On Friday Morning, North Korea test detonated a 10 megaton nuclear device, their biggest yet. The U.S., Japan, South Korea, and China were all quick to condemn the actions and have called for an emergency meeting on Friday of the U.N. Security Council. This comes shortly after the U.S. announced plans to instal a missile defense system in South Korea, a move that North Korea called an act of war. There are rumours that North Korea is getting its nuclear material from Pakistan.
Early on Friday morning (local time) North Korea detonated their 5th nuclear bomb. This time, the bomb was their biggest yet at 10 megatons. To put things into perspective the bomb we dropped on Hiroshima was 15 megatons.
The blast was first reported in South Korea as an earthquake, but was later to be found originating from Punggye-ri, the same test site as the four previous explosives.
