Not really. The important thing here is the building. The world would be outraged if Israel bulldozed it (they had no problem bulldozing buildings full of people in Jenin - killing children).
How can you repeat this lie? Even the Palestinian press is admitting it is not true.
As for the building, they could easily pump gas into it and kill everybody in there. In fact, they could just let them starve, intead of sending in food and water. But they won't. Because their morality won't let them.
By the way, what do you think the Palestinians would do if the situation were reversed? That church would be history and everyone in it (if they were Jewish) would be dead as of the first day.
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.
