On Aug. 4, a huge explosion in the Port of Beirut rocked the city, killing 192 people and injuring over 6,000 people.
The blast caused damage estimated at $15 billion, according to official figures, and occurred as Lebanon was already experiencing its worst economic crisis, with a dramatic drop in the value of the Lebanese pound against the dollar.
