Ammonium Nitrate

A massive explosion rocked Beirut on Tuesday, flattening much of the city’s port, damaging buildings across the capital and sending a giant mushroom cloud into the sky. More than 100 people are feared dead and thousands injured, with bodies buried in the rubble, officials said.

The emerging official narrative is that a welder accidentally set off a stockpile of fireworks, which then caused more than 2,700 tons of ammonium nitrate stored at a nearby warehouse to explode.
