They are leaning towards a gas explosion, but other sources (Meth Lab, Bomb, etc) have not been ruled out as of yet. Over 30 homes un-inhabitable and over 100 homes damaged. The explosion was heard up to 15 miles away, and blew open doors as far as 1/4 mile away.'
Locals are thinking meth lab, or bomb making, gas company is saying it wasn't them... And the russians are saying it was a CIA drone and 2 hellfire missiles.
