The Aug. 4 detonation at a port warehouse of what authorities said was more than 2,000 tonnes of ammonium nitrate injured more than 6,000 and destroyed swathes of the Mediterranean capital, compounding months of political and economic meltdown.
Excavators were seen removing the rubble on Tuesday (August 11).
The explosion gutted entire neighborhoods, leaving 250,000 people homeless, razing businesses and destroying critical grain supplies.
Lebanese security officials had warned the prime minister and president that 2,750 tonnes of ammonium nitrate stored in Beirut's port posed a security risk and could destroy the capital if it exploded, according to documents seen by Reuters and senior security sources.
A report by the General Directorate of State Security on events leading up to the explosion included a reference to a private letter sent to President Michel Aoun and Prime Minister Hassan Diab on July 20.
Rebuilding Beirut will likely run into the billions of dollars. Economists forecast the blast could wipe up to 25% off of the country's GDP.
