The Ukrainian army regained the control of the village, Chalaya recalled, adding there were "so many violent clashes" when they left the village on May 14.
"Intense fighting currently continues in that area. Everything has burned," she said.
Chalaya said she has only her son alive and she could not move comfortably without his help due to her health problems.
"I am sick. It is such a disease that I cannot sit. I can only lie down or walk with the walking stick."
The Russians, she claimed, used cluster munitions during the fighting, and there were civilians who died as a result of the attacks in the village.
"I had a very close friend. While the poor woman was sitting at home, a piece of bomb ripped her from life," she said.
'EVERYTHING AROUND DESTROYED'
Nikolay Mikushev, 63, who also took shelter in the sanatorium, barely holding back his tears, said they lived with his wife in the town of Staryi Saltiv, which suffered the most severe wounds of the war in the Kharkiv region.
Mikushev said the heaviest clashes there started in May, adding that their grandchildren brought them to the sanatorium on May 30.
"All the bridges leading to the town were blown up. Everything around was destroyed during the clashes," he said.
Mikushev recalled that the house they lived in became unusable, adding that they "lived in shelters without bread" for two months.
"We became refugees. We do not know what to do or where to go," he said.
He also stressed that the attacks still continue in the town which is very close to Kharkiv, and that civilians are not allowed to enter there.
Last week, UN High Commissioner for Refugees Filippo Grandi said, "Ukraine has displaced between 12 and 14 million people, depending on how you count."
