Along with other Al-Qaeda affiliates, GICM was banned worldwide by the UN 1267 Committee in the aftermath of the September 11 attacks in 2001. The group was later linked to several terrorist attacks. In 2003 twelve suicide bombers from the associated group Salafia Jihadia were responsible for coordinated suicide bombings in Casablanca that killed 33 people. At least eight of the people convicted after the bombings were accused of being members of the GICM. Nourredine Nafia, an important early leader of the group was sentenced to 20 years in prison, and Saad Houssaini, the group's suspected military committee chief (arrested in 2007) was sentenced to 15 years.
