Eyewitness FREEPERS are not very little information.
It appears we have several on this thread.
Meaning little to go on to assume it was part of a failed terrorist attack. That was the arguement with some when I posted that LAST NIGHT ..People were in "assumption" mode last night and it was turning this story into another 9/11..Just woke up here and it looks like the story hasen't moved much since last night .
It may be a good idea to have a FReeper take a photo of the blast site to get an idea of the magnitude. Also if there was a second explosion, photographic evidencew of that area would also be useful.
