Flag of the Organisation of Islamic Cooperation

The flag of the Organisation of Islamic Cooperation is white with a green crescent and globe, with the Kaaba at the center of the globe. In 2011 this replaced the earlier flag, adopted in 1981, which featured a green background with an upward-facing red crescent enveloped in a white disc in the center; inside the disc, the words "Allahu Akbar" were written in Arabic calligraphy.
