When Tanks Meet Children in Gaza

This sounds like a pretty awful incident in Gaza:

Israel Defense Forces tank fire killed at least 30 Palestinians at a United Nations school in the Gaza Strip on Tuesday, UN officials and medical sources and at two hospitals said.

Palestinian officials had initially said that 40 people were killed in the attack, but UN sources put the number at 30 killed and 55 wounded.

An IDF spokesman said that troops had fired mortar rounds at the school, after militants barricaded inside shot mortar shells at the Israeli forces.

"Initial checks ... show that from inside the school mortars were fired at Israeli forces," a spokesman said. "In response, the forces fired a number of mortar rounds into the area."

The attack brought the Palestinian death toll to nearly 600 in Israel's 11-day offensive on the Hamas-ruled coastal territory.

I wonder how many of the 30 dead were children? I'm guessing quite a lot. I have to wonder if the members of the Israeli government, if they were really honest with themselves, would really think their actions in Gaza are justified?
