A picture grabbed on images obtained by AFP in Mali on January 18, 2013 and filmed with a mobile phone in 2012 shows a rebel convoy in the Malian desert . BM-21 Grad rocket launchers, the type of equipment that was once part of the Libyan army's arsenal, make up part of the convoy as do Mali army vehicles. The Malian army backed by French troops wrested a key central town from Islamist rebels, as the UN warned up to a million people could be driven from their homes by fighting in coming months. As a dramatic hostage siege unfolded in neighbouring Algeria -- where Islamists took hundreds captive in a gas field to retaliate for the week-old military intervention in Mali, sparking a deadly commando raid -- fighting has continued unabated on the ground in Mali.
