The August 4th explosion in Beirut’s port is an unprecedented disaster. The explosion of 2700 tonnes of ammonium nitrite confiscated from a vessel in 2013 and stored in the Port, has killed over 135 people, injured over 5000, and left more than 300 000 homeless in a city of rubble and shattered glass. What caused the material to catch fire and explode is still unclear. This text takes a closer look at the Port and the neighbourhoods affected, and the socio-economic moment in which the explosion happened.
