The group was founded in September 2003, as an
umbrella organization for
guerrillas, with former members of
Ansar al-Islam who had fled to
Iran after a 2003 joint operation by Iraqi and US forces. Their goal was to expel U.S. occupation forces from Iraq. Following the twin Sunni and Shiite
uprisings of the spring and summer of 2004, and the subsequent decrease in U.S patrols and the creation of "no-go" areas in the Sunni Triangle, Ansar al-Sunna was believed to be part of a loose coalition of insurgent groups (also including guerrillas from al-Tawhid wal Jihad) controlling the Sunni cities of Fallujah, Ramadi,
Samarra, and
Baquba (U.S. offensives later largely wrested control from Baquba, Fallujah, and Samarra, although underground guerrilla resistance forces still had a strong presence in those cities). The United States and
Iraqi Interim governments linked Ansar al-Sunna with
Abu Musab al-Zarqawi's,
Jama'at al-Tawhid wal-Jihad (al-Qaeda in Iraq). In October 2004 Ansar al-Sunna released a video beheading of a Turkish truck driver on its website. The kidnappers on the video identified themselves as members of al-Tawhid wal Jihad (Source: MERIA). However a letter intercepted by the American military in January 2007 revealed the two groups had begun feuding. In July 2007 representatives of the Jaish Ansar al-Sunna were instrumental in forming an alliance of Sunni militant groups to prepare for the withdrawal of American and allied forces. The new alliance was composed of seven groupings explicitly excluding al-Qaeda and the Baath-party. This delimitation revealed a split between al-Qaeda and Ansar al-Sunna over tactics, alleged attacks on Iraqi Shia civilians being a main point of difference. In December 2007, the leader of the Ansar al-Sunnah, Abu Abdullah al-Shafi, issued a communique acknowledging that the group was simply another name for
Ansar al-Islam. The communique went on to state that from that point on, they would return to operating under the name of Ansar al-Islam. A small group still using the name "Jamaat Ansar al-Sunna" has been active in the
surge of militant activity in 2014. ==Suicide bombings==
