“After flying for half an hour, the pilot announced a technical incident and turned around,” the CEO of Air Algerie said, as cited by the Algerie 1 news website.

He added that the nature of the failure “is still unknown for the moment.”

According to the Algerian television channel Ennahar TV, all the passengers are safe and another aircraft will transfer from to Marseille as soon as possible.

A source from Air Algerie also told RIA Novosti that the aircraft returned to Algiers due to technical glitch and landed safely.

“The plane disappeared half an hour after taking off when it was some 7,000 meters above the Mediterranean, but half an hour ago it returned to Algerian International Airport,” the source told RIA Novosti.

The source added that the crew decided to turn back “due to a technical failure” and then informed air traffic controllers at Algiers Airport.
