An Air Algerie plane similar to the one that has gone missing
A flight operated by Air Algerie carrying 110 passengers and a crew of six has disappeared from the radar during a journey from Burkina Faso to Algiers.
The official Algerian news agency said air navigation services lost track of the Swiftair plane 50 minutes after take-off in the early hours of Thursday.
Swiftair, the private Spanish airline, confirmed 116 people  were on board.
Map of the location where the Algerian crash is thought to have gone missing
The flight path of Flight AH5017 from Ouagadougou, the capital of the west African nation of Burkina Faso, to Algiers was not immediately clear.
Ouagadougou is almost directly south of Algiers, passing over Mali where unrest continues in the north.
A senior French official said it was unlikely that fighters in Mali had weaponry that could shoot down a plane.
The official, who spoke on condition of anonymity, said the fighters have shoulder-fired weapons which could not hit an aircraft at cruising altitude.
