Three people have been injured in a plane crash near the Russian-Ukrainian border. The crash is believed to be the result of a collision between a plane and a dam.

The incident is the latest in a series of high-profile plane crashes in recent years. The U.S. Air Force says it is investigating the cause of the crash, which took place in the early hours of Monday morning. The FAA says the crash was caused by the collapse of a dam in the area, which is under control of Russian authorities.
