one person told me the entire city is like a mass grave. cnn's don lemon sat down with a family that escaped that city and has been reunited. >> there was one day i went out to call my son. he said, leave the city. and my wife was cooking over an open fire and there was an explosion and she started shaking. i just couldn't do it to my wife anymore. i would never forgive myself if something happened to her. >> joining me now is the anchor at cnn, don lemon, great to see you here. you have been following this family for some time. i think it's instructive about the situation in mariupol just how harrowing it was there and just how challenging it is to get out. >> they didn't want to leave. one is a hospice worker. the uncle, or i should say the dad of the young lady. the daughter and her husband.
