The latest bi-weekly GANSO report from Gaza, covering the period from October 31 to November 20, has some interesting statistics.
During that time period there were 36 mortars and 16 rockets that were intended to be shot to Israel. Of those 36 mortars, 5 of them fell short or exploded prematurely. Of the 16 rockets, 7 of them exploded before launch or landed in Gaza.
Those accidents resulted in the injury of 7 Gazans during those two weeks, and as far as I can tell, zero Israelis.
GANSO says that about 30% of rockets and mortars fired out of Gaza do not reach Israel. In this time period the percentage was 14% of the mortars and 44% of the rockets.
Another mortar fell short today.
