Nothing in the linked article backs up the implication that only members of Helbollah’s militant wing had these.

It did, however, mention that an 8 year old girl was killed by one of them. Which is a foreseeable consequence of widely distributing a bunch of bombs and then detonating them without regard for who’s nearby.

Some sources are saying that some medics have been victims. Pagers are apparently a very useful resource for emergencies/medics (see motorola website).

The pagers were not secure at all also.
