"The suit contains more than 100 testimonies of witnesses and a large number of documents," he said, adding that Ukraine accuses Moscow of abducting orphans in Donbas and taking them to Russian territory.
Petrenko also noted that this is the second lawsuit with the ECHR against Russia related to the events in Donbas.
Earlier, the Russian media reported that the Russian Federation may freeze its participation in the European Court of Human Rights and cut contributions to this organization.
