Following increasing frustration within the armed forces over the Malian government's ineffective strategies to suppress a Tuareg rebellion in northern Mali, a military coup on 21 March 2012 overthrew President Amadou Toumani Touré and overturned the 1992 constitution. The Tuareg rebels of the MNLA and Ansar Dine took advantage of the confusion to make swift gains, and on 1 April 2012, Timbuktu was captured from the Malian military.
