Apparently there are rumors starting that it wasn't a meteorite but some kind of U.S weapons testing. I'm sure this site is probably like Weekly World News but still scary if these rumors are even considered. This was also supposably reported in another paper but it is all in Russian and I can't read it.

It never takes long for the conspiracy theories to start.
If the US was going to test any kind of weapon, why would they do it over Russia? North Korea........Iran.......that would make more sense.
