A massive explosion occurred at the Port of Beirut due to the ignition of a cache of fireworks and 2,750 tonnes of ammonium nitrate, which was stored in a warehouse. The blast was reportedly triggered by welders who were repairing a broken door at the warehouse. The Lebanese government has resigned in response to the disaster, with the prime minister citing chronic corruption as the underlying cause. The incident has sparked widespread protests and calls for reform in the country.
