Russian security officers Yevgeny Yerofeyev and Alexander Alexandrov, who are being tried in Ukraine, may be transferred to Russia to serve their sentences at home, Ukrainian Deputy Prosecutor General and Chief Military Prosecutor Anatoliy Matios said.

"In line with international legal treaties ratified by many countries, including Russia, citizens of other countries may serve their sentences in their own countries through an extradition exchange. That is, the state whose citizens have committed a crime in Ukrainian territory may accept their citizens, and must ensure that they serve their sentence in keeping with the conviction handed down to them by Ukraine," Matios said on the Hromadske.TV television channel.

A decision on Alexandrov's and Yerofeyev's possible extradition might be made if Russia makes a relevant request, he said.

Military prosecutors are not directly related to a negotiating process regarding the swap of captives, he said.

The officers of the Main Intelligence Directorate (GRU) of the General Staff of the Russian Armed Forces, Alexander Alexandrov and Yevgeny Yerofeyev, were captured near the town of Schastia, Luhansk region of Ukraine, in an attempt to seize a strategic bridge. Both were injured and later underwent surgeries at the Ukrainian Defense Ministry's main clinical hospital in Kyiv.

On May 19, Ukrainian detectives told the Russians that they were suspected of terrorism. The Kyiv Shevchenkivsky District Court ordered their arrest on May 22.

The Board of the High Specialized Court of Ukraine decided on October 15 that Kyiv Holosiyivskiy District Court would hear the case of the Russians. The court began to hear the case merits on November 10.

The Russian Defense Ministry has insisted that Alexandrov and Yerofeyev were not on military duty at the moment of their detention in Ukraine.
