Moscow (CNN) -- A passenger plane overshot the runway at a Moscow airport Saturday, killing four of the eight people on board, emergency management officials said.
The Russian Red Wings Airlines flight was arriving to Vnukovo International Airport from the Czech Republic when it crashed through a fence, Russia's Ministry of Emergency Situations said.
Four others were injured in the crash of the Tupolev Tu-204 airliner, officials said. As of Sunday morning, the four survivors were hospitalized in Moscow with severe, traumatic brain injuries.
All eight people on board were crew members. Initial reports indicated 12 people were aboard the plane, but authorities later revised that figure. The plane is capable of carrying 210 people.
Video taken from a nearby highway shows debris from the plane, including a tire and what looks like a row of seats, flying onto the roadway. No serious injuries were reported from the highway.
The cause of the crash is not known. Officials say the weather, pilot error and technical malfunctions could be possibilities.
