All 71 passengers and crew were killed when the Saratov Airlines jet went down minutes after taking off from Domodedovo airport on Sunday afternoon. Officials say they are considering weather conditions, human error and technical failure as possible causes. They did not mention the possibility of terrorism.

The Antonov An-148 was en route to Orsk in the Ural mountains. It crashed near the village of Argunovo, about 80km south-east of Moscow. Wreckage and body parts are strewn over a large area.

More than 700 people are involved in the search operation, with the remote crash site being searched on foot with the aid of drones, the BBC reported.
