Islamic Movement for Change was in the news briefly in late 2003 as being one of the many Islamic movements dedicated to overthrowing Muammar Qaddafi.  However, given that this is apparently an al-Qaeda priority as well, it is highly likely that the group is merely used as a front for al-Qaeda.

The Islamic Movement of Holy Warriors was responsible for the kidnapping of a Lebanese contractor named Muhammad Raad in Iraq in August of 2004. The group released Raad after about two weeks in captivity at the behest of the Committee of Muslim Scholars. Raad has claimed that the group is responsible for countless murders. <p><br />According to Raad, he was kidnapped by the group and held without food or water for six days. After that period, he was transferred to a group within the larger organization  --  the Seif al-Islam Brigade of the Islamic Movement of Holy Warriors. The brigade then took him to a hut in a remote area near the Jordanian border, which he says was covered in dried blood and "reeked of death." Raad then claims that he was forced to watch the beheading of an Egyptian man named Mohammed Fawzi Abdul Mutwalli, who the captors claimed was an "American agent." The group told Raad that it was meant to be a lesson to him and all Lebanese citizens that working with occupation forces would be punished. Western officials have been unable to confirm or deny that someone named Mohammed Fawzi Abdul Mutwalli was kidnapped and killed around that time. <p><br />After more than two weeks in captivity, the brigade of the Islamic Movement of Holy Warriors holding Raad released him, explaining in a video that they were responding to an appeal from the Committee of Muslim Scholars  --  a prominent group of Sunni religious leaders. In the video, the Islamic Movement of Holy Warriors expressed their opinion that the people of Lebanon were their Islamic brothers but warned that if they cooperated with coalition forces, they would be treated as coalition forces.

The Islamic Movement of Holy Warriors has not been publicly linked to any terrorist incidents other than Muhammad Raad's capture. However, if Raad's statements are correct, the group carries out a large number of murders below the radar of mainstream media. Also, the group's generic name makes it possible, even likely, that the same group of people has been claiming responsibility for kidnappings and other incidents under aliases.
