Missing Russian jet pilot 'picked up by Syrian army'
Russian defence official Lt-Gen Sergey Rudskoy said the two pilots were shot at from the ground as they parachuted from their burning plane - one of them was killed.
There have been various reports about the fate of the second airman.
Lt-Gen Rudskoy also said a rescue team using two Mi-8 helicopters had attempted to rescue the two pilots.
"During the operation, one of the helicopters came under small-arms fire, was damaged and made an emergency landing on neutral territory," he said.
"One naval infantryman serving under contract was killed."
He said the rest of the rescue team were safely evacuated from the area to Russia's Humaymim air base near Latakia in Syria.
Syrian rebels say they blew up the helicopter shortly after it landed with an anti-tank missile, releasing footage of the attack.
