The only reason why there was some concern about nuclear material during the Beirut explosion was due to that one radiation detection center in Italy going off at the same time. But that was confirmed to be a glitch, and not chronologically consistent with the explosion. Furthermore, the Beirut explosion couldn't have been an actual nuclear bomb based upon the amount of damage and appearance of the blast, so it would've been a dirty bomb at worst."Coming from "the North" tactical nuclear weapons arrived in Turkey. The impact of these weapons is similar to the explosion in the harbor of Beirut."
The explosion in Beirut was non-nuclear, despite what anyone says. I'm still researching the site, but this single line indicates to me they are an alarmist organization. I have no idea what their agenda is, but I would take anything on that site with a grain of salt for now.
I'll let you know what else I find, but I need some time to dig.
