ALGIERS, Algeria (AP) — An Air Algerie flight from Burkina Faso in West Africa, to Algiers, has disappeared from radar.

The official Algerian news agency says air navigation services lost track of the plane 50 minutes after takeoff early today.

Air Algerie is quoted as saying, "In keeping with procedures, Air Algerie has launched its emergency plan."

The plane's flight path passes over Mali, where unrest continues in the north.
