KURNOOL/VISAKHAPATNAM: Some parents heaved a sigh of relief after speaking to their children, who reached Ukraine’s borders and were being looked after by Indian officials on Wednesday, for the first time in days. Out of the 29 identified youngsters from Kurnool district who were studying MBBS in Ukraine, four have been brought back home, so far. Many others are set to board a number of ‘Operation Ganga’ flights in the days to come. B Lakshmanna from Adoni town, whose son Arun Kumar is a second-year MBBS student at Zaporizhzhia University, said he was relieved after hearing his son’s voice on Wednesday morning.
