A pinned comment allagedly by someone speaking Korean is repeated below:
"I will translate. He said: Ok yeah in really poor Korean. The translator spoke Korean and said you have been on the front since January the third. He responded: Yeah Ok. At
4:38 he said: Is it possible? Also, in poor Korean. I am calling BS. The poor guy is terrified for his life. And probably tired after having to learn those phrases. Korean? No idea. At least he might live and get to go home unlike most of the other prisoners Ukraine deals with."
I am still a bit sceptical myself, we shall see as the situation develops and more data is available.
Regarding the military ID. Ukrainians claim there was a military id proclaiming the bearer to be from Yakutja. We do not know if the ID really was with the bearer.
