A sect of Chechen soldiers have executed their own wounded Russian troops, witnesses have claimed.
They attacked the soldiers in a field hospital northwest of Bucha, reports state as the barbaric action in Ukraine continue.
The fighters, known as Kadyrovtsy, allegedly killed their own comrades and have turned a glass factory into a chilling 'torture chamber'.
The deputy commander in Ukraine's Territorial Defense Forces spoke to local witnesses on his recent visit to Borodyanka.
Artem Hurin reportedly said Kadyrovtsy would 'shoot dead' wounded Russian soldiers on the spot.
He was first to visit the town after Vladimir Putin's soldiers retreated last month.
Mr Hurin said: "They would bring heavily wounded Russian soldiers to a big hospital they had there, and those who were very heavily wounded, they would just shoot them. No one other than the Kadyrovtsy did this.
"They didn't allow them to do anything. There they just killed people through binoculars for example. They just shot them."
They had executed people as early as March 5, residents said.
The Daily Beast reports that he said he saw evidence of horrifying stories.
He claims residents were tortured and raped by lawless Russian troops.
The commander says they also 'executed civilians' who were found lifeless on the street.
One woman also recalled how she endured four days of torture by one Kadyrovtsy soldier and another from Belarus.
They brutally shot her husband in the head, she said.
Autopsies have been carried out on mutilated corpses from Bucha, Irpin and Borodianka, The Guardian reports.
Many showed signs of torture, with some having bullet holes in the back.
Some of the bodies were so badly disfigured investigators have been unable to identify the victim.
Vladyslav Pirovskyi, a Ukrainian forensic doctor who carried out the autopsies, told The Guardian : "We already have a few cases which suggest that these women had been raped before being shot to death.
"We can't give more details as my colleagues are still collecting the data and we still have hundreds of bodies to examine."
He added: "There are many burnt bodies, and heavily disfigured bodies that are just impossible to identify - the face could be smashed into pieces, you can't put it back together, sometimes there's no head at all."
