A former South Korean naval special forces soldier has returned home after fighting for Ukraine as a member of an "international legion" of volunteers.
Rhee Keun, also known as Ken Rhee, was being investigated for defying a government ban on travel to Ukraine.
Rhee posted pictures and video footage of his experience in Ukraine on social media, and his return was broadcast live on television.
"I haven't left the battlefield completely but came to recover from injuries. I want to go back ... because the war has not ended, there's still a lot to do," Rhee said at the airport.
Rhee said he was suffering from a cruciate ligament injury in both legs. However, he was able to walk.
He said he would cooperate in the investigation.
