and that would be consistent with israel's stated objective of destroying the tunnels hamas uses to burrow under the ground to go under the israel/gaza border. there are casualties. we were at the hospital earlier today. quite a few of the casualties are women and children, and these are people that we spoke to who live in that border area. israel is trying it seems to avoid some civilian casualties telling palestinians to leave the conflict areas. the problem is, gaza city and all of the gaza strip are sealed areas. there's not very many places where palestinians can go. so in a certain sense, they are shooting at a captive population. that said, there have still been some rockets fired from here toward israel. we've been watching several launches over the course of the afternoon and hamas is threatening to do more of these kind of attacks. so no talk at this stage of finding any kind of negotiated settlement.
