It's tragic, it's sad,  but school children weren't the target. They were told to leave and to go south (or other direction) and they chose to stay. They heard the message because they have cell phones. That's about all they have. And sheep. And that's because they gave all their money to Hamas who chose to buy billions of dollars in weapons and leave their citizens jobless, so they could go fight Jews. And now they have no money, no homes, and no children. And they continue to let Hamas run around that place. The Jews aren't having it, because they were just going to grow up and kill Jews. Good for them. Sorry about the children and any of the others that chose to stay and were killed.
They need to take a look around for real. It's indeed a terrible shame, but it's war, and it's a war that was provoked  by the murder and immolation of men, women, and children in Israel. I think her words fall on deaf ears where I'm from, because the more she hates Jews the more people like us hate her. Hate is a very compelling thing, more so than love perhaps. But I don't think that the pity is accomplishing anything. So she should find something more compelling than the hate that is fueling the whole thing.
