A Ukrainian officer was killed in a shooting at a military facility on the outskirts of the Crimean capital Simferopol on Tuesday, a military spokesman said, but it was unclear who was behind the incident.
"An officer was wounded in the neck," said Vladislav Seleznyov, a Ukrainian military spokesman in Crimea.
Many Ukrainian military facilities in Crimea have been under the control of Russian forces for several weeks after Russian troops poured into the Black Sea peninsula ahead of a referendum at the weekend which handed over control from Ukraine to Russia.
There was no immediate evidence that Russian soldiers were involved in Tuesday's incident, witnesses said.
