"Over the last week, from militant-controlled territory we have recovered the bodies of 81 people who died from January to February 2015," he said.
"We have already identified 19 of the bodies. Their names will be soon published on the Web site of the Ministry of Defense of Ukraine," Selezniov said.
He also said that forensic medical examination experts were involved in the identification of the other dead bodies.
There was heavy fighting in eastern Ukraine from January until mid-February, despite a ceasefire having been declared on September 9 last year.
Russian-backed militants also ignored another ceasefire declared on February 15, attacking and capturing a formerly government-held town in Donetsk region – Debaltseve.
Ukraine says it has lost control of more than 500 square kilometers of its territory since the September 9 “ceasefire,” as militants supported by Russian troops attacked and took over villages and road checkpoints in the Donbas.
