In short: On August 4, 2020, 2,750 tonnes of ammonium nitrate ignited at the Port of Beirut, triggering a shockwave that shattered the city. The disaster, which killed 218 people and caused billions in damages, was the result of years of bureaucratic negligence and a forgotten cargo ship abandoned in the harbor.

The catastrophe originated from the MV Rhosus, a cargo ship that docked in Beirut in November 2013. Carrying 2,750 tonnes of ammonium nitrate destined for Mozambique, the vessel was deemed unseaworthy and seized by authorities in 2014 due to unpaid fees. The volatile cargo was offloaded into Warehouse 12, where it remained for six years despite repeated warnings from customs officials about the severe danger it posed.

On the afternoon of August 4, 2020, a fire broke out in the warehouse, likely ignited by welding work. The blaze spread to stored fireworks before detonating the ammonium nitrate. The resulting explosion produced energy equivalent to approximately 0.5 to 1.1 kilotons of TNT, creating a massive crater and seismic activity felt as far away as Cyprus. The blast destroyed the port’s grain elevator, which held a strategic reserve of cereals, further crippling a country already reeling from a severe financial crisis and the COVID-19 pandemic.

The human and structural toll was immense. Beyond the 218 confirmed deaths and 7,000 injuries, the explosion left 300,000 people homeless and caused an estimated US$15 billion in property damage. Hospitals, museums, and embassies were severely impacted, with Saint George Hospital forced to close after its intensive care facilities were destroyed. In the aftermath, the Lebanese government faced intense scrutiny, leading to the resignation of Prime Minister Hassan Diab’s cabinet and a complex, ongoing investigation into the systemic corruption and inaction that allowed the disaster to occur.
