It doesn't say if the Jordanians killed were the attackers of if they were killed by other Arabs. I couldn't find the news on Arutz 7. I found it on a self-hating Jewish site (see the link). They got it from the AP. It says Israel isn't letting people report on it which is why I couldn't find the news on Arutz 7. So we don't have a clear picture of who did what. Were the killed Jordanians working at the Embassy and killed by their fellow Arabs or were they killed by Israeli security while attempting to kill Israelis?
