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 207 deaths, 7,500 injuries, and US$15 billion in property damage, and leaving an estimated 300,000 people homeless. A cargo of 2,750 tonnes of the substance (equivalent to around 1.1 kilotons of TNT) had been stored in a warehouse without proper safety measures for the previous six years, after having been confiscated by the Lebanese authorities from the abandoned ship MV Rhosus. The explosion was preceded by a fire in the same warehouse, but as of April 2021, the exact cause of the detonation is still under investigation.
