No North Korea nuke test
 

...according to reports coming out of South Korea...who is reporting that there were probably two explosions that took place at a missle testing/manufacturing center and possibly a munitions manufacturing center.

or was it just a forest fire ?

I do not know...South Korea is now reporting that one and maybe two explosions took place. I suppose that a forest fire (if there is one) could have caused the explosion/explosions...or the explosion/explosions could have caused a forest fire. It appears to be definite that a nuke was not tested.
