Why did they have loudspeakers warning the women and children to leave then? How were they to know they were still in buildings? Of course, they could have just strapped a bomb around a 10-year old and sent him in to blow himself up. That is so honorable you know and no one ever complains about that action.
Dunno. Seeing as they buried children alive under the rubble, I have no clue why they bothered with the "warnings."
