“The Russian Defense Ministry’s commission investigating the cause of the crash has found fragments of the crewmembers’ bodies at the crash site,” the ministry said in a statement.
The Su-24 crashed seven kilometers from the Marinovka airport near the southern city of Volgograd. There were two crewmen on board.
The Defense Ministry grounded all Su-24 flights until investigations unveil the cause of the deadly crash. A special commission is now working at the scene. It consists of an expert panel from the Russian Armed Forces' flight safety authority and the Air Force.
The Sukhoi Su-24 twin-engine frontline bomber was developed in the Soviet Union. Its modified version, Su-24M, entered service in 1983 and is still in use by some former Soviet states.
In 2010, the Russian Air Force decided to replace its Su-24s with modern Su-34s, with the full replacement to be completed by 2020.
