Not sure why this was flagged, it's certainly a novel way of striking the enemy, regardless of the political undertones.
Reuters seems to have a bit more details, and is probably a bit less biased than current URL (timesofisrael.com): https://www.reuters.com/world/middle-east/dozens-hezbollah-m...
What's definitely novel is the scale, perhaps not the tactic, which has been used many times before (speculative assumption being that the devices were tempered with)
