Hamas and other terrorist groups never announced total casualties of their members, as far as I can tell.
Now, Islamic Jihad says 135 of its members were killed during that war.
Maybe a few of them succumbed to injuries afterwards, but 14 seems a bit high for that.
Which means that here are an additional dozen or so more people who were reported as "innocent civilians" by NGOs like Amnesty and the UN who were, in fact, terrorists.
