This is an explosion of ammonia nitrate that happened in China in 2015. Does it look the same as the beruit explosion to you? https://www.youtube.com/watch?time_continue=38&v=zxbf_o9nMog&feature=emb_title It is at night, but you can see that the smoke is not brown and the flaming material flying through the air was non existent in the Beirut explosion.  Also, you can see many secondary explosions in the Beirut explosion that leads me to believe it was an ammo depot. Another discrepancy I noticed was that the explosion in China was of 800 tons of Ammonia Nitrate.  The explosion in Beirut was allegedly of 2750 tons of it which means the Beirut explosion should be over 3 times larger than the explosion in China.
