Wild ass guess - gas leak then explosion. It is a bakery after all.
Don’t think it is terrorism (what is the point of blowing up a bakery?)
Nor do I think it is a false flag (again, a bakery).
If it was terrorism or a false flag then a police station or a school would have been a better target.
But it too little information to make anything but a wild ass guess, and since this is FREE REPUBLIC home of the wild ass guesses I thought I would add my own /s
Planet small bomb as cause gas leak.
Yep no one would ever think of that.
