Another working theory is that it could just be an opportunistic cyber attack - compromising lithium batteries. Though some of the videos coming out look like a bigger explosion that just a battery going off: https://www.reddit.com/r/lebanon/comments/1fizgag/ha_member_...
Terrorist is relative... my country was liberated from the nazis by what would then be called "terrorists".
For many people down there, they're considered freedom fighters, and israel is considered to be commiting genocide in palestine... And the sentiment is spreading, not just in lebanon.
To respond to person above, KLA was a terrorist organization recgnized by USA and many others too, then they became "valuable" in their geopolitical schemes, and US helped them, and many countries literally protected them in kosovo, including the president there, who was a member of KLA.
Nah, batteries don't explode like that... heat, burst of fire somewhere, sure... full on explosion, no way. This was done somewhere in the supply chain, devices were replaced, explosives were added.
And israel will wonder why suddenly even more lebanonis want to fight them after.
