This is the type of information you can find in Operation World: The Definitive Prayer Guide to Every Nation.
After I finished reading Beyond the Veils of Yemen I reached for this book so I could learn more about about Yemen. I learned that it is a conservative Muslim country based on shrai'a law with very little religious freedom, is one of the poorest Arab countries and only 30% of the women can read So today I'm praying for Yemen. And in a few days I have a friend who is going to Haiti. I'll be praying for Haiti.
This is a wonderful resource that I recommend to all! Oh, and check out their website for more resources.
