I read an interesting article, paragraph 20 I think, earlier today that might answer your query, at:
http://www.timesonline.co.uk/tol/news/world/middle_east/article2461421.ece
I hope it is ok to link to the site above. Moderators, please correct if I'm in error.
I’m not really sure why the URL is not valid or cannot be loaded.
My fellow Freepers, i’m sure will help me out.
