A man holds a sign reading : 'France = MNLA (National Movement for the Liberation of Azawad) out' as he takes part in a demonstration in front of the French Ambassy in Bamako on May 19, 2014 to denounce the occupation by rebels of Kidal, 1,500 kilometres (900 miles) northeast of the capital Bamako and accuse France of complicity with armed groups. Mali sent troops on May 19 to retake the rebel stronghold of Kidal after Tuareg separatists seized local government offices, taking hostages and engaging the army in a firefight in which dozens were killed.
