Authorities have lost contact with an Air Algerie flight en route from Ouagadougou in Burkina Faso to Algiers with 110 passengers on board, Algeria's APS state news agency and a Spanish airline company said on Thursday.
APS said authorities lost contact with flight AH 5017 an hour after it took off from Burkina Faso.
Spanish private airline company Swiftair confirmed it had no contact with its MD-83 aircraft operated by Air Algerie, which it said was carrying 110 passengers and six crew. An Algieran official had earlier said it was an Airbus A320.
The company said in a notice posted on its website that the aircraft took off from Burkina Faso at 0117 local time and was supposed to land in Algiers at 0510 local time but never reached its destination.
