I cannot imagine the fear and unknown being brought up in their minds. You would think your city has just been nuked when a disaster like this happens. Here is footage from Beirut, Lebanon earlier today (their 7pm). How horrifying.
The nation's government isn't ruling out Islamic terrorists for starting the explosion.
This first video, I imagined if I was there and how scary it must be. The emotions, the unknown. Hearing the people screaming and the fear... My gosh. Prayers to them all.
