The structure itself has a hole on the top, and a hole in the center pillar. I'm assuming someone might've put it in there, and the explosion would cause it to violently react as the immense pressure in a tight space would fracture parts of it, but not completely shatter and explode it completely apart. It wasn't that large of an explosion so it was meant to do damage, but not say, demolish it.
It probably cause it to fall apart which did a good deal of damage having it fall on it's own weight. But I don't think that it was launched. It could have easily been thrown or dropped from a drone perhaps, which are fairly easily accessible to anyone and when you open the "option" to anyone no one can be more right or wrong without more specific details being confirmed in the investigation.
