Tuesday's (August 4) blast at port warehouses storing highly explosive material was the most powerful in years in Beirut, already reeling from an economic crisis and a surge in coronavirus infections.

President Michel Aoun said that 2,750 tonnes of ammonium nitrate, used in fertilisers and bombs, had been stored for six years at the port without safety measures, and he said that was "unacceptable."

Officials did not say what caused the blaze that set off the blast. A security source and local media said it was started by welding work being carried out on a hole in the warehouse.
