It mentions that claim but now there is no evidence provided of it either, yet.
More interesting to me is the news that it wasn't the extraction that created casualties, it was the group somehow getting stuck and the militant counterattack that spurred escalation. While I do not condone the Israeli attitude towards casualties, I don't condone the Hamas attitude towards them either.
They are, but you are allowed to reveal yourself. Hence the warning from the judge that would be a bad idea.
