MOSCOW: One person died apparently of a heart attack and 18 people sought medical help when a plane skidded off a runway in Russia’s Olympic city of Sochi, slid into a river and caught fire during landing early Saturday, officials said.

The Boeing 737 flying from Moscow with 166 passengers and six crew members overshot a runway as it attempted to land in the Black Sea resort city of Sochi, damaged a wing and caught fire.

“As a result of the crash landing at Sochi airport 18 sought medical help,” regional health authorities said. The injured included three children, said investigators, who opened a criminal probe.

During the rescue operation an airport employee died, possibly of a heart attack, a spokesperson for the Sochi Airport told AFP in a statement.

Sixteen ambulance crews worked at the scene, authorities said, adding that the fire had been put out.

The plane was operated by the Utair airline.
