Quoting an unnamed Israeli website, they write:
Citing Israeli soldiers, the Israeli army spent the entire night on the terrifying edge of the Gaza Strip, after a clash with the Palestinian resistance.
A soldier said: "It is as if we were fighting ghosts, we did not see the enemy and do not know where the bullets and rockets were coming from. It was a terrifying night by all accounts, we were looking for a military target, but we did not find anyone."
There you have it - unnamed quotes from an unnamed source that is only visible on Arab terrorist websites that coincides with how the Gaza terrorists fantasize the battle will go.
That's normally all the evidence Mondoweiss needs to report something as factual.
