The Aden Abyan Islamic Army has strong ties with the al-Qaeda network.[4]

The group was formed sometime between mid-1990s as a loose guerrilla network of a few dozen men. Issued the first series of political and religious statements on Yemeni and world affairs.

The group,"Aden-Abyan was formed sometime in either 1996 or 1997 as a loose guerrilla network of a few dozen men—a mix of veterans of the Soviet-Afghan war and Islamists from various countries."[6] In terms of the formation and background on the AAIA,The name “Aden-Abyan Islamic Army” is a right-wing terrorist organization that is composed of religious ultra-conservatives, mujahideen, and deposed aristocrats. Other supporters of the AAIA include Yemenis of Aden, Abyan and liberals, socialists, and social conservatives[7] The groups stated goal is to "hoist the banner of al-Jihad, and fight secularism in Yemen and the Arab countries."[8] These were seen through the series of political and religious statements on Yemeni and world affairs."[6] "The name “Aden-Abyan Islamic Army” appeals to the right wing, but also to some extent echoes the frustrations of Yemenis from Aden, Abyan and elsewhere in the former South, including liberals and socialists as well as social conservatives."[7]

Claimed attacksEdit

The Aden-Abyan took responsibility for the October 2002 bombing of a French oil tanker, which killed a crew member.

Many believe that this attack was connected to the USS Cole bombing in 2000. This was one the attack that this group is best known for. Some events that took place previously to this include the kidnapping in 1988, where 16 of Western tourists were held hostage, some of which were killed in a failed rescue attempt.[9] In addition to this, the Aden Abyan Islamic Army also claimed "attacks on Yemeni socialists prior to the 1993 parliamentary elections"[7] This group has continued to wreak havoc on the lives of people in Aden and throughout the west. One of these include the attack in October of 2000, where two suicide bombers aligned with Aden Abyan to explode their boat along the USS Cole"[4] This became a very important attack for the group because it gained a lot of recognition from people around the world being able to see what the groups intentions were.


This group mostly teamed up with the al-Qaeda networks in order to take part in attacks, which gave them credibility as a terrorist organization.

This group is mostly known for their work with Al-Qaida, having assisted the group in various attacks on western enemies. Their work with al-Qaeda has brought credibility to the group by showing that they are capable of working with a group as large as AQ.Through their work with the large group, the Aden Abyan Islamic Army "received financial and material support from Al-Qaida leader Osama bin Laden (deceased) in exchange for its support for Al-Qaida’s agenda."[10] This gave the group a sense of power, being given tangible and intangible support from al-Qaeda in exchange for help in their endeavors.
