Ukraine investigating over 25,000 possible war crimes

STORY: Of those charged, around 15 are in Ukrainian custody and the remaining 120 remain at large, Yuriy Bilousov, head of the war crimes department of the Prosecutor General's office said in an interview in the capital Kyiv.

Thirteen cases have been submitted to courts and seven verdicts have been issued, he said.

In May, a 21-year-old captured Russian soldier became the first person to be convicted in a war crimes trial in Ukraine since Russia invaded on Feb. 24. He was sentenced to life in prison for killing an unarmed civilian.
