There is not a single part of that little strip of land that is not a "civilian area". Gaza is a very densely populated little area. It does not look good for Israel that they have attacked UN-sanctioned schools and UN offices in Gaza, either. Israel has very accurate munitions and high-res intelligence images, so the "oops" excuse won't play out very well.So what? That doesn't obviate them of the responsibility of choosing civilian areas to be the battleground.
