As wiki would have us believe...
(On 4 August 2020, a large amount of ammonium nitrate stored at the port of the city of Beirut, the capital of Lebanon, exploded, causing at least 204 deaths, 6,500 injuries, and US$15 billion in property damage, and leaving an estimated 300,000 people homeless. Wikipedia)
Any thoughts?
Seems like some sort of attack to me. I think Lebanon was shipping weapons, and then it got blown up by another faction. Attack could have been electronic or drone based.
