Maybe the radiation readings are yet to come out or to be covered up but as to the the blinding flash, that is not a requirement or affect of every weapon system of the many different types (yes, there are) of smaller lower grade tactical nukes. The military’s of not just the United States but others have weapon systems that we are not privy to or have knowledge of. I still say it was a small military tactical nuke or a very crude, low yield nuclear bomb. 100 “mother of all bombs” could not have the same signature concussion or devastating effect that this incident shows.
Tinfoil hat stuff. You're saying every university and government within a 1000 mile radius of Beirut is in on the coverup? Nope, not buying it.

Here's the smallest nuke ever fielded by the US --> video here
The blast yield is about 20 tons of TNT, about 1 or 2 *percent* of the yield of the explosion in Beirut.
Note: observers all wearing dark glasses to protect their eyes from the flash. Explosion produces blinding flash.
I rest my case. The only way you would *not* get a blinding flash from a nuclear device is if you set it off underground or under water.
That's ammonium nitrate with a lot of dirt on top if it, or it's an oxygen-poor explosive like TNT (which will give a dirty black cloud), or something. But not just ammonium nitrate.
