to accusations of Malian crimes against the Tuareg people. Despite this, the Islamists targeted MNLA checkpoints and other military installations with suicide bombers in retaliation. In-fighting also occurred when Chadian intervention forces were accused of firing upon Tuareg civilians. Peace deal A peace deal was reached in June 2013 between the MNLA and Malian government giving military lease over Tuareg rebel held land also, Tuareg greater autonomy which was requested after the MNLA revoked their Independence claim. This allowed the North to participate in Malian presidential elections the same month. The ceasefire didn't last long before Malian troops clashed with rebels in skirmishes. Continued insurgency In February 2014, a massacre of a Malian general's family who were ethnic Tuareg led to an ethnic conflict between Fulani Islamists and Tuareg MNLA separatists. A massacre deliberately targeting Tuareg majority civilians was carried out by Islamists killing over 30 unarmed men. 2017 There was a referendum scheduled for 2017 on gaining autonomy and renaming the northern regions into "Azawad". However, Mali's President Ibrahim Boubacar Keita shelved the plans for the referendum on constitutional reforms that were met with opposition and ignited regular street protests. Geography The local climate is desert or semi-desert. Reuters wrote of the terrain: "Much of the land is the Sahara desert at its most inhospitable: rock, sand dunes and dust scored by shifting tracks." Some definitions of Azawad also include parts of northern Niger and southern Algeria, adjacent areas to the south and the north though in its declaration of independence, the MNLA did not advance territorial claims on those areas. Traditionally, Azawad has referred to the sandplains north of Timbuktu. In geological terms, it is a mosaic of river, swamp, lake, and wind-borne deposits, while aeolian processes have proven the most imprinting. About 6500 BC, Azawad was a 90,000-square kilometres marshy and lake basin. The area of today's Timbuktu was probably permanently flooded. In the deeper parts of Azawad, there were large lakes, partly recharged by rainfall, partly by exposed groundwater. Seasonal lakes and creeks were fed by overflow of the Niger River. The annual Niger flood was diffused throughout the Azawad by a network of palaeochannels spread out over an area of 180 by 130 kilometres. The most important of these paleochannels is the Wadi el-Ahmar, which is 1 200 metres wide at its southern end, at the Niger bend, and winds 70 to 100 kilometres northward.
