If Israel has used flechette rounds, it has not been reported.
Your silly story by a Palestinian propaganda group that one person had been wounded by a flechette weeks ago is most unlikely to be true.

IDF has not even used phosphorus smoke rounds, never mind anti-personnel rounds.
I have seen no convincing reports of their use either.
That is not me denying anything Jim.
just saying that there is nothing to deny yet.

Instead of accusing me of this and that, make a point for me to answer.
