Hezbollah like most other similar organisations is not a primarily military organisation even though they are a paramilitary one. The vast majority of the members of Hezbollah have non-military roles of various kinds.

Civilians are shown to be in proximity of these devices when they are exploding. It appears that these devices were all triggered simultaneously, rather than waiting for individual targets to be isolated.

One reason is that Hezbollah is not a purely military organization, and has political, medical and educational arms. Another is that some of the reported casualties are the family of Hezbollah members.
