The Majelis Mujahideen Indonesia (MMI), or Indonesian Mujahedeen Council, is an umbrella organisation of Indonesian Islamist groups. During the 2004 Indian Ocean earthquake, MMI established a command post at the Iskandar Muda Air Force base in Banda Aceh city to "help evacuate dead bodies, distribute aid and give spiritual guidance to survivors." In December 2007, it was reported that MMI members were involved in attacks on several Ahmadiyah mosques in Indonesia. The attacks were motivated by a fatwa issued a month earlier by Indonesian Council of Ulama (MUI) against heresy.
