The most flagrantly misleading headline I've seen in months. Intended to provoke outrage at Hezbollah.
You might think that this means that Hezbollah was responsible for the cache of ammonium nitrate in the port of Beirut, and they were stockpiling it there with plans to use it in an attack on Israel. But both of those are false.
Ammonium nitrate is a readily available fertilizer, and explosive. (A ton might be used to fertilize about 12 acres of corn.) As such, it's widely used in truck bombs, including the one used by Timothy McVeigh.
The article points out that Hezbollah-linked terrorists in London had stockpiled enough for a truck bomb (a few thousand pounds), as had another group in Germany.
The article also points out a Hezbollah leader's assertion that Israel's large stockpile of ammonium nitrate in Haifa was a huge vulnerability, and that it could be exploded by Hezbollah missiles - and that they have, so far, chosen not to target it.
So, technically, the two claims are true. Hezbollah had, in the past, stored an amount of ammonium nitrate 1000x smaller than the Beirut stockpile...but no involvement is alleged with the Beirut supply. And Hezbollah had threatened to target an ammonium nitrate depot in Israel, but not to use the Beirut stockpile as a weapon. And the two not-technically-false statements are stitched together so that most people who just read the headline will jump to the wrong conclusion. And people are posting and sharing it, either aware or unaware of the intentional deception.
I won't do the author or publication the favor of linking to them, I'm sure you can find them if you want to look it up.
