Alikhalid--thank you for your comprehensive definition. Would you include Turkey, Iran or Israel in you description? They sometimes get lumped in, but (like North Africa and Iraq) it seems a bit fuzzy. I've sometimes heard them included and excluded by various media outlets. But then I have also heard someone on the BBC also include Pakistan!

If we are using a genetic definition, as suggested by another poster above, Lebanon has been shown to have very different markers than Saudi Arabia.
