peaceful protests in beruit?

anybody got an info on this? Big explosion but I can't find any cause.

Waiting to see if Iran involved (my hunch is yes).

I heard it was a "fireworks factory" that caught fire.

But I have also been told that it may have been a bomb assembly site for those nice guys of Hamas & Hezbollah.

Regardless of the cause, it was one hell of an explosion.

Outside of an atomic bomb I can’t recall ever seeing an explosion like that.
