Work has begun in Ukraine to exhume over 400 bodies from a mass burial site in the newly liberated Kharkiv region.
Officials says the first body to be recovered shows signs of a violent death.
Lesia Vasylenko is a member of the Ukrainian parliament - she says there is evidence of torture:
"Izium has become a collective for more evidence sites of just horrendous atrocities - that were being committed by men in uniform... Russian men in uniform against peaceful Ukrainian civilians".
