Islamic Caliphate As-Saffah
The Islamic Caliphate As-Saffah, or simply As-Saffah, is perhaps the bloodiest and most powerful terrorist group in the whole world nowadays. Its proliferation has been quick and very virulent, raising thousands of followers in a very short time, managing to extend its tentacles through a good part of the Middle East, Asia, Africa and with cells infiltrated in Europe and North America.
