Nobody heard about this?

Hi All,
I am surprised that nobody has been discussing the massive explosion in Donetsk the video below is the clearest of the explosion I have seen, I know what it looks like but on other videos there can be seen smaller flashes indicating to me an Artillery Strike of Shells/Rockets with the secondary explosion that many videoed. Many have jumped straight in and described it as a Nuclear explosion as of yet there has been no definite explanation other than about it being a Chemical plant that made the different powders that were put into explosives, also that other weapons stored at the site all this is what went up, the Ukrainian Army have said it was a rocket attack they fired the rest they don’t know ? some interesting questions that need to be answered I think, well gentlemen what do you think Nuke or Just very large explosion :confused:
