An American pilot aboard a Ukrainian Air Force fighter jet was killed when the aircraft crashed Tuesday during a training exercise in Ukraine, officials said.
The Ukrainian Defense Ministry said two pilots aboard the Su-27 had been killed in the crash, which took place in the Khmelnytskyi region located in the western part of the country about 200 miles west of the capital of Kiev.
The U.S. Air Force command based in Europe said the American pilot, who was not identified, was among the two pilots on board at the time.
The crash took place during joint military training between the U.S. military and Ukrainian counterparts, known as Clear Sky 2018.
