On 4 August 2020, a large amount of ammonium nitrate stored at the Port of Beirut in the capital city of Lebanon exploded, causing at least 218 deaths, 7,000 injuries, and US$15 billion in property damage, as well as leaving an estimated 300,000 people homeless. A cargo of 2,750 tonnes of the substance had been stored in a warehouse without proper safety measures for the previous six years after having been confiscated by Lebanese authorities from the abandoned ship MV Rhosus. The explosion was preceded by a fire in the same warehouse.

Ammonium nitrate is a chemical compound with the formula NH4NO3. It is a white crystalline salt consisting of ions of ammonium and nitrate. It is highly soluble in water and hygroscopic as a solid, although it does not form hydrates. It is predominantly used in agriculture as a high-nitrogen fertilizer.
