Ukrainian volunteer activist Yuriy Mysiahin has said Ukrainian infantry troops captured an important member of a terrorist organization near the Russian-occupied town of Horlivka.
"The captive has turned out to be a 'big fish.' He has been fighting in the ranks of illegal armed formations since 2014," he wrote on Facebook on September 19.
According to unconfirmed reports, he is a citizen of a post-Soviet state.
As UNIAN reported earlier, Russia's hybrid military forces on Wednesday mounted five attacks on Ukrainian positions in Donbas, eastern Ukraine.
