Just on radio news; now they are saying that it was one large explosion; your theory is starting to make a lot of sense.
If it came in from outside it must have been more than a mortar round or RPG. I don't think the Sunni Jihaddis have any heavy artillery, but who knows?
My money at this point would be that it was an inside job - IED in a garbage can most likely.
Keep us posted, if anybody has a clue.
There's one photo of a big hole in the roof/ceiling. I wonder if it wasn't an IED detonated from above?
RIP
I say just let loose Iraqi troops on their sorry a**es..
