I dont beieve anyone is saying no one died. What they are saying is that we dont know whether or not the Palestinians blew up their own people to get a story. The Palestinians are not above doing that.
For a country that is still in the 19th century they always seem to have a video camera at hand.
I realize that no one is saying that no one died. (There's an interesting spoonerism or tautology or oxymoron or limerick of something lurking in that sentence...) I just meant to point out, that even if some of the dead walked, some of the victims were genuine enough.
