French soldiers prepare their ammunitions on January 16, 2013 at the military airbase in Bamako, before their deployment as part of the “Serval” operation against Islamists occupying northern Mali. France has deployed 700 troops in and around Paris, Interior Minister Manuel Valls revealed Tuesday in the latest indicator of mounting concern over potential reprisals for military intervention in Mali. Leaders of the militant Islamist groups under attack in the West African state have warned that France has “opened the doors of hell” by unleashing its warplanes and have called on fellow extremists to hit back on French soil.
