Ukraine says it has charged two suspected Russian soldiers who had been captured in the country's east with involvement in "terrorist activity."
An adviser for the Ukrainian Security Service (SBU), Markiyan Lubkivsky, wrote on Facebook on May 20 that the two men were also allowed to telephone their relatives in Russia.
Kyiv says it has captured the two men, identified as Yevgeny Yerofeyev and Aleksandr Aleksandrov, in the eastern region of Luhansk on May 16.
The men claimed in a video that they were active Russian servicemen, but Moscow said they were no longer employed by the state when they were captured.
Russia has constantly denied accusations by Kyiv and the West that it is providing weapons, training, and personnel to rebels in eastern Ukraine who are involved in a conflict that has killed more than 6,100 people since April 2014.
