The UN High Commissioner for Human Rights said Monday that she was “horrified” by the images of bodies discovered in the Ukrainian city of Bucha, after the withdrawal of Russian troops.

“The information that is coming out of this area and others raises serious and worrying questions about possible war crimes and serious violations of international humanitarian law as well as serious violations of human rights,” Michelle Bachelet stressed in a statement, also asking that “preserve all evidence.”

In addition to the identification of the bodies to be able to notify the relatives, Bachelet asked that everything be put in place to be able to determine the causes of death.

Corpses of civilians in Bucha, strewn in the streets, some with their hands tied behind their backs, prompted a wave of convictions.

The Ukrainian authorities and their allies accuse the Russian soldiers of having committed atrocities, but Moscow denies these accusations and suggests a staging by kyiv.

“It is vital to carry out an independent and effective investigation” into what happened in Bucha so that justice and reparation can be done for the victims and their families, stressed the former president of Chile.
