In an attempt to cause a large scale explotion, one which has the potential of mass casualties, the Iranians fired 2 missiles from south lebanon. One hit close to the refinaries, and another hit Carmel mountain.
These missiles were not fired in retaliation, they were test shots - to calibrate the bigger missiles they plan for tommorrow.
The refinaries sit in the midst of a heavy populated bay. In case of a direct hit, residents of 6 towns are at risk. We are talking about the scale of 70 thousands casualties.
