Some free apps disappeared from android app store for some of the medial east countries

A lot of android's free apps disappeared from app store for users in countries located in the medial east like Saudi Arabia, and some other countries, and one of these apps is Angry Birds game and Skype app. Some people said they were able to find it in the app store website, but still the didn't find it in their devices. I don't think Google is intended to do that it most be a technical problem, but still Google should have announced that there is a problem.
