Founded in 1988 by Abjullah Yusuf Azzam, Al-Qaeda is an international union of the largest denomination of Islam, militant organization. It has been named a terrorist organization, by many countries, and has attacked civilian and military targets in many nations. The most prominent attack was on September 11, 2001, often referred as 9/11. The U.S. government, following these attacks, launched a military and intelligence campaign against Al-Qaeda known as the War on Terror. The intentions of Al-Qaeda are to end foreign influence in Muslim countries and to create a new Islamic leadership.
The specific practices of Al-Qaeda include the use of suicide attacks and simultaneous bombing of different targets. These are behavioral attributes of members of the organization who have taken a pledge of loyalty to bin Laden, or are in or have undergone training in on of Al-Qaeda’s camps located in Afghanistan or Sudan.
The leadership of Al Qaeda has become geographically inaccessible, since 9/11 and the launching of the War on Terrorism and due to its secrecy and structure of semi-autonomous groups, the size and degree of responsibility for particular attacks are difficult to establish.
