The men may be exchanged for Ukrainians illegally imprisoned in Russia
Aleksandr Aleksandrov and Yevgeniy Yerofeyev are sentenced to 14 years behind bars and asset seizure.
On April 18, the Kyiv district court found them guilty of waging 'an aggressive war', participating in terrorist organizations, and launching deadly attacks on Ukrainian soldiers.
They were acquitted of three other charges: weapon smuggling, carrying firearms without a license, and illegally crossing the temporarily occupied territories.
Two alleged Russian special forces officers, Yevgeniy Yerofeyev and Aleksandr Aleksandrov, were captured in May 2015 in Luhansk region in eastern Ukraine, and charged with murdering a Ukrainian soldier, creating a terrorist group, and waging aggressive war against the country.
Both servicemen claimed being innocent, since they had been dismissed from the Russian armed forces before coming to Ukraine.
Now both Aleksandrov and Yerofeyev may be exchanged for Ukrainians held by Kremlin.
Nearly a month ago Ukraine's President Petro Poroshenko stated he was ready to transfer the accused soldiers to Russia in return for the release of Ukrainian pilot and MP Nadiya Savchenko, who illegally imprisoned and convicted in Russia.
