Russia's Defense Ministry says a military aircraft crashed during a training flight and both pilots were killed.
The Su-24 bomber crashed today while taking off from an airfield in the Khabarovsk region in Russia's Far East, the ministry said in a statement, adding that the cause of the crash wasn't yet known.
The crash is the fifth one involving a Russian military aircraft in the past month, but the first with fatalities.
On Friday, a MiG-29 fighter jet went down in southern Russia, but the pilot ejected safely. Another MiG-29 crashed in southern Russia in June, its crew of two bailing out safely.
Also in June, a Su-34 bomber ran off the runway upon landing and overturned, and a Tu-95 bomber also ran off the runway.
