KIEV (Reuters) - A Soviet-designed Su-25 jet aircraft crashed in south-eastern Ukraine on Wednesday during a training exercise, killing its pilot, the Ukrainian military said.
The incident took place at around 0400 ET in the Zaporizhya region, about 450 km (280 miles) from Kiev, a defense ministry spokesman said, without specifying the cause of the crash.
Ukraine's military has operated a fleet of around 50 of the Su-25 "Grach" single-seat, twin-engine jets.
It is not known how many are still in active service, with some reported shot down by pro-Russian separatists during the country's 16-month conflict.
