Yeah, this should remove any doubt that there were explosives involved. At the 500 to 1000 mA hour capacity typically used in pagers, even tampering with the battery's venting in an attempt to build up gas pressure would at worst result in a pop and some smoke from the top of the bag.

Blowing a hole in the side of the bag and sending debris for several meters is obviously not plausible with that quantity of lithium.

The explosion in the video does show visible smoke, but there is not a visible flame or fire.

That is what explosives look like. You're thinking 80's movies explosions, made with barrels of gas.

It's about the lack of visible flame, but more about the velocity of the burn, essentially instantaneous at normal camera speeds.

Looks pretty discriminate to me, only the pager holder was affected. I've seen multiple videos with very close bystanders completely unharmed. And whoever holds a pager from Hezbollah is a member of an armed terrorist group officially at war with Israel.

Your on-the-ground, in-depth and thorough analysis of the situation is appreciated ...

All the media reports say that these were the pagers distributed by Hezbollah to its members.

Objectively this is therefore targeted, not indiscriminate...

Right but these were exploding in public right next to innocent people. There's CCTV footage of some of them exploding.

That's still a targeted attack and it seems from the media reports so far that the "collateral damage" is remarkably low, actually.

How did they make sure that only pagers carried by the armed wing of Hezbollah exploded, and not say an MP, nor one of their media workers, nor a manager in one of their hospitals? How did they know that no civilians were dangerously close when they exploded?

They didn’t. They put explosions in all the pagers which were distributed to all members of Hezbollah, military or not, and indiscriminately exploded them all at the same time, regardless of who was near the pager at the time.

This is incorrect in a disturbing way. How can something be "targeted" if the attackers simply do not and cannot know where the attacks are going to take place, physically and geographically?
