By Scott Stewart Mali has experienced perhaps the most significant external repercussions from the downfall of the regime of Libyan leader Moammar Gadhafi. Stratfor has discussed the impact of the conflict in Libya on the wider region since international intervention began in March 2011. Instability in Libya due to that country's deep internal fault lines meant that re-establishing a government would prove difficult. As we pointed out, that instability could spread to neighboring countries as weapons and combatants flow outward from Libya. Reports now indicate that thousands of armed Tuareg tribesmen who previously served in Gadhafi's military have returned home to Mali. The influx of this large number of well-armed and well-trained fighters, led by a former Libyan army colonel, has re-energized the long-simmering Tuareg insurgency against the Malian government. These Tuareg insurgents have formed a new group, the National Movement for the Liberation of Azawad (MNLA).
