Here's what I wrote on Monday-
The main Iranian nuke facility in Fordo seems to have had a massive explosion. News is spotty; Drudge links to a WND story, but there seems to be little mainstream collaboration. There's shades of the Egyptian-lynching-by-crucifix story that was covered in the anti-Islamist press but never confirmed outside of it; the story's a bit too good to be true, but could be true nonetheless.
As it turned out, my sniffer was right; it was merely a rumor with no basis in fact. There seems to a tendency to take stories that fit an anti-Muslim world-view and run with them if they seem truthy. The fact that broader media doesn't cover it can be written off as "this is stuff they don't want you to know about."
However, there wasn't any good reason for the MSM to cover up bad news about the Iranian nuke program. This news would call off the preventative-strike dogs for a while if the saboteur managed to save Israel a bomber run over look-the-other-way Arab neighbor's territories, so they would have had a vested interested in playing things up rather than downplaying it.
