Al-Qaeda is a pan-Islamist militant organization led by Sunni Jihadists who self-identify as a vanguard spearheading a global Islamist revolution to unite the Muslim world under a supra-national Islamic caliphate. Its membership is mostly composed of Arabs, but also includes people from other ethnic groups. Al-Qaeda has mounted attacks on civilian, economic and military targets of the US and its allies; such as the 1998 US embassy bombings, the USS Cole bombing and the September 11 attacks. The organization is designated as a terrorist group by NATO, UN Security Council, the European Union, and various countries around the world.
