Fighters from the Al Qaeda-linked Islamist group MUJWA, who are travelling with a convoy including Burkina Faso foreign minister Djibril Bassole, stand guard in Gao, northern Mali, August 7, 2012. Bassole, the lead mediator in regional efforts to end unrest in Mali, told rebels there that they had to cut ties to terrorist movements like al Qaeda before any peace talks could begin, when he travelled to the rebel-held north for the first time on Tuesday.
