A passenger plane from Dubai carrying about 60 people has crashed on landing in the Russian city of Rostov-on-Don, Russian officials said.
Survivors were unlikely, a representative of the region's emergency ministry said on Saturday.
Rostov's regional emergency ministry said there were 55 passengers aboard and six crew, based on preliminary information.
The reports said the plane was a Boeing 737 operated by Emirati airline FlyDubai.
Russia's state-run RT network tweeted a clip of what appeared to be a large explosion.
"We are aware of an incident involving our flight FZ981 from Dubai to Rostov On Don," a FlyDubai spokesman told Al Jazeera.
"We are investigating further details and will publish an update once more information is available."
Boeing tweeted that it was gathering more information.
