Tetyana Kharko lost contact on May 20 with her brother, Major Sergiy Volynsky, one of the last soldiers that left the Azovstal steel plant in Mariupol, after weeks of heavy shellings. "Where he is now, in what condition, does he need help, is he being tortured..., we don't know anything", she laments during an interview with AFP in Kyiv. He is one of hundreds of Azovstal fighters who surrendered to the Russian troops that took besieged port whose families and loved ones still do not know if they are dead or alive.
