In 2012, Tuareg and other peoples in northern Mali's Azawad region started an insurgency in the north under the banner of the National Movement for the Liberation of Azawad. The Malian Army complained that it was ill-equipped to fight the insurgents, who had benefited from an influx of heavy weaponry from the 2011 Libyan civil war as well as other sources. On 21 March 2012 elements of the army staged a military coup d'état and formed the "National Committee for the Restoration of Democracy and State". The scheduled elections were then called into question after coup leaders suspended the constitution and arrested government ministers, while promising that, at some time in the future, elections would be held to return governance to civilian control. Following the coup, the rebels made further advances to capture the three biggest cities in the north. On 1 April 2012, under pressure from the Economic Community of West African States (ECOWAS), the leader of the junta Captain Amadou Sanogo announced that the constitution would be restored.
