Israel has consistently lied about the military nature of their targets in Gaza. I see no reason to believe they behave any differently in Lebanon.

Also, even if they were all military—which they probably weren’t—they were still going about their civilian lives far away from the battlefield, as they posed no threat to anybody.

Now that some time has passed we know a little more about the victims. Including a press conference by Lebanon’s Minister of Health Firass Abiad. There have been 12 recorded deaths so far. Of those were 4 medical workers, one 8 year old girl, and one 11 year old boy. The press conference noted that many of those carrying the pagers were civilians. And made special mention of the toll this scale of an attack had on their medical system.

The best interpretation for Israel here is that they conducted a terrorist attack in a civilian against an armed group during their civilian lives, inflicting at least some civilian casualties. But we know how Israel conducts it self in Gaza and elsewhere in Palestine, and we have every reason to expect their intentions were far more nefarious.
