Director-General of Lebanon Public Security Abbas Ibrahim said: “The storage area contained highly explosive materials confiscated years ago. To discuss fireworks is laughable.”

The explosive material allegedly contained sodium nitrate.

The explosion was so massive that its shockwave shattered windows miles away from the blast.
