My guess, which seems to be backed up with recent news - Somebody bought a bunch of Motorola Pagers, then modified them. They added a high explosive (oxidizer is part of the explosive propellent) to the pager, such that it would behave normally. The explosive would go off when a "special" message was sent, otherwise behave normally.
These pagers were then secretly distributed to Hezbollah and were then given to their members. A generic message preceded the "special message" by a few seconds, so that the Hezbollah member would take the pager out and look at it.
This action was replicated today, using hand-held radios (which could likely contain a higher mass of high explosives). Seems pretty targeted to me, and the targeting of the enemy (vs launching random missiles into Israel) seems like a good use of technology.
