A video has been released of the French hostage Serge Lazarevic who has been held for two years in the Sahara by al Qaeda’s North African wing.
In it Lazarevic says he is ill and in a critical condition.
He called on France to negotiate with his captors, as they did in 2010 for four other French nationals who were kidnapped and then set free.
Lazarevic, is the last of a series of French hostages held by militants in the Sahara region.
The presence of hostages in the area has complicated French-led efforts to drive al Qaeda-linked militants from northern Mali, which was over-run by Islamists in 2012.
France sent troops to Mali, its former colony,last year.
