Since the submitted URL (http://www.theaustralian.com.au/news/world/the-times/saudi-d...) is blocked, we've switched to this one for the time being. I tremble, because any Daily Mail article provokes a storm on HN, let alone one about 9-11. But the article appears to be substantive and to contain new information, and those are our criteria. So let's see what happens. If anyone finds a more substantive article we can change the URL again.
