It was not immediately clear what caused the fire at the facility, which was decimated by the Aug. 4 explosion when nearly 3,000 tons of ammonium nitrates detonated. A column of black smoke billowed from the port with orange flames leaping from the ground. The Aug. 4 explosion killed more than 190 people, injured around 6,500 and damaged thousands of buildings in the Lebanese capital. The sight of another huge fire a month later created panic among residents traumatized by last month's explosion.
